Full Text Available RESUMO:Embasado em uma literatura específica sobre o movimento estudantil, a ação política dos jovens e também dos movimentos sociais, este trabalho procura discutir os meios de reação dos estudantes, em Belo Horizonte, entre os anos de 1969 e 1975, contra uma legislação específica (Lei Suplicy de Lacerda, Decreto Aragão e Decreto-Lei 477. O resgate dos mecanismos de reação do movimento estudantil permite uma análise que procura ir além da tradicional ênfase dada à luta armada, como mecanismo, por excelência, da ação dos estudantes. Desse modo, pensar as articulações e a manutenção da representatividade estudantil que construíram os meios de reação desse movimento em Belo Horizonte acrescenta novas perspectivas em relação a esse objeto. Assim, a análise da imprensa estudantil se mostrou relevante, no sentido de trazer contribuições para o entendimento da organização dos estudantes em torno de suas entidades representativas. PALAVRAS-CHAVE: Movimento Estudantil em Belo Horizonte, Decreto-Lei 477, Imprensa estudantil. ABSTRACT: Based in a specific literature about the student movement, political action of the youths and also about social movements, this essay seeks to discuss the means of students reaction, in Belo Horizonte, between the years of 1969 and 1975, against a specific legislation (Law Suplicy de Lacerda, Decree Aragão and Decree-Law 477.  Recovering student movements` mechanisms of reaction permits an analysis that seeks going beyond the traditional emphasis given to the armed resistance as the main mechanism of students action.  Of this way, thinking about the articulations and maintenance of the student representativeness, that built the means of movement’s reaction in Belo Horizonte, provides news perspectives regarding that subject.  Like this, the analysis of the student press was shown prominent, in the sense of bringing contributions for the understanding of the student’s organization

This study analyzed the association between self-reported diagnosis of hearing loss and individual and occupational factors among urban transportation workers in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil. The sample size was calculated by quotas and stratified by occupation (drivers and fare collectors) in the urban transportation companies in Belo Horizonte, Betim, and Contagem. Data were collected with face-to-face interviews and recorded by the interviewers on netbooks. The dependent variable was defined as an affirmative response to the question on prevailing medical diagnosis of hearing loss. The independent variables were organized in three blocks: social and demographic characteristics, lifestyle, and work aspects. Diagnosis of hearing loss was reported by 213 of the 1,527 workers and was associated with age and diagnosis of tinnitus. At the occupational level, hearing loss was associated with history of sick leave, time-on-the-job, and two environmental risks, unbearable noise and whole-body vibration. Measures to prevent hearing loss are needed for urban transportation workers.

Os resultados demonstraram que a maior parte dos rejeitos gerados na capital é de base cerâmica, oriundos de obras de reformas residenciais de casas, classificadas em padrão normal de acabamento, localizadas, sobretudo, nas regionais Centro-sul e Pampulha. Pela determinação destas características foi possível estabelecer recomendações aplicáveis tanto às usinas de reciclagem como ao sistema de gerenciamento de resíduos da capital como forma de minimizar as causas da variabilidade dos agregados reciclados gerados a partir dos RCC.The aim of this article was to expose the current state of affairs regarding the generation of waste in Belo Horizonte so as to present the main characteristics of construction civil waste (CCW involving their typology, origin, predominance in their composition, as well as data about the construction sites that generated them, their construction pattern and type of building. The results show that the majority of the waste generated in Belo Horizonte is of ceramic base, deriving from house renovations construction sites classified as normal finishing standard located mainly in the center south and Pampulha areas. By determining these characteristics it was possible to establish recommendations applicable to the recycling plants as well as to the waste management system in Belo Horizonte to minimize the causes of the variability of the recycled aggregates generated from construction civil waste.

Full Text Available OBJETIVO: Fatores genéticos e ambientais são conhecidos por sua importância na gênese de grande parte das doenças. É possível estudá-los pela observação da prevalência de agravos nas populações, bem como das causas de mortalidade, buscando-se uma correlação com os hábitos sociais e origens étnicas e familiares dos indivíduos. Nestes estudos, destacam-se as comunidades nas quais podem-se verificar vínculos sociais e genéticos entre seus membros. A comunidade judaica de Belo Horizonte se encaixa nesses critérios. Ela se consolidou na década de 20 do século passado e, atualmente, a Federação Israelita de Minas Gerais (FISEMG tem cadastro de aproximadamente 600 famílias. Este estudo pretende definir o padrão de mortalidade nessa comunidade, e como ele se modificou a partir de sua formação. MÉTODOS: Foram recuperados dados a partir dos arquivos do Instituto Histórico Israelita Mineiro, da FISEMG e dos Cemitérios Israelita e do Bonfim, oriundos de registros históricos e guias de sepultamento, no período de 1926 a 2003. RESULTADOS: Foram estudados 601 registros de óbitos, sendo 61,6% de homens e 38,4% de mulheres. As doenças infecto-parasitárias, dentre elas a tuberculose, ocorreram com maior freqüência nas décadas de 30 e 40 e decresceram nas décadas seguintes. As doenças do aparelho circulatório foram as causas de óbito mais prevalentes a partir da década de 40. CONCLUSÃO: Houve mudança nos padrões de mortalidade da população judaica de Belo Horizonte.OBJECTIVE: Genetic and environmental factors are known for their importance in the genesis of the majority of diseases. It is possible to study them through the observation of prevalence of diseases, and also the mortality causes, relating it to social habits and ethnical and familial origins of the individuals.

Full Text Available The main objective of this cross-sectional study was to analyze factors associated with alcohol consumption among adult women living in Belo Horizonte, Minas Gerais State, Brazil, in 2011. Data for Belo Horizonte were obtained from the VIGITEL system (Telephone-Based Surveillance of Risk and Protective Factors for Chronic Diseases. Alcohol use was defined as self-reported intake of at least one dose in the previous 30 days; alcohol abuse was defined as four or more doses on at least one occasion during the same period. Polytomous logistic regression was used to evaluate factors associated with alcohol use and abuse. Alcohol use was more prevalent among women 25 to 34 years of age. Alcohol abuse was associated with age, schooling, health status, and smoking. The results suggest the need for policies to prevent alcohol abuse among women, especially targeting those who are younger, single, smokers, and with more education.

Entre os alunos enquadrados na definição de "necessidades especiais" encontram-se aqueles com autismo, caracterizados por apresentarem alterações na interação social, na comunicação e pela presença de padrões estereotipados de comportamento. A prefeitura de Belo Horizonte - MG vem desenvolvendo ações com o intuito de favorecer o acesso de estudantes com autismo a escolas regulares do município, porém dados sobre o andamento deste processo são escassos. O objetivo desse estudo consistiu em caracterizar os alunos com autismo matriculados em escolas municipais regulares de Belo Horizonte, assim como descrever a maneira pela qual essa escolarização vem ocorrendo nas escolas comuns, a partir da perspectiva de seus professores. Participaram do estudo trinta e três professores da rede regular de ensino do município que tinham contato direto e diário com alunos com autismo. Foram utilizados um questionário semi-estruturado e a escala CARS (Childhood Autism Rating Scale.

Full Text Available A expansão de condomínios horizontais esteve diretamente relacionada às condições históricas que acarretaram a deterioração e o abandono do centro urbano de Belo Horizonte, entre meados das décadas de 1960 e 1970. Nesse contexto, alguns tiveram o privilégio de escolher o sonho da casa no campo, atraídos por promessas de uma vida renovada, mergulhados nos paradoxos do desenvolvimento e dos dramas sociais, políticos e ambientais em curso no Brasil durante a ditadura civil-militar. Cientistas e técnicos realizavam as primeiras avaliações dos dilemas da poluição ambiental urbana. Entretanto, temas ambientais se configuravam como assunto extemporâneo e distante da política, subestimados por setores brasileiros de direita e esquerda. A perda de qualidade de vida em Belo Horizonte recebeu soluções individuais, por vezes com aspectos comunitários. O caráter simultâneo desses processos na capital mineira esclarece casos históricos similares em outras grandes metrópoles brasileiras e latino-americanas.

This article seeks to describe the profile of treatment and internment in public psychiatric hospitals in Belo Horizonte, Brazil, from 2002 to 2011. The changes in the characteristics of treatment and the profiles of the patients treated are analyzed in the context of health care reform. It is a study of temporal series with trend analysis by means of linear regression. There was a reduction in the total of patients treated in the period under scrutiny. Inversely, there was an increase in internments with a reduction in length of stay, though no change in readmission rates. Patients from Belo Horizonte prevailed, however a relative increase in demand from the surrounding area was observed. There was a reversal in the prevalence of morbidity switching from psychotic disorders to disorders resulting from the use of alcohol and/or other drugs. The alteration observed in the profile of treatment in public psychiatric hospitals in Belo Horizonte was concomitant with the progressive implementation of community mental health services, which have probably met the demand that was formerly directed to these hospitals. Currently the psychiatric hospital is not the first, much less the only venue for treatment in the mental health network in Minas Gerais.

Full Text Available A study on the phlebotomine sand fly fauna in Belo Horizonte city, state of Minas Gerais, Brazil, was carried out. From April 2001 to March 2003, monthly systematic collections were performed in three houses from each of the nine regions of the city, using CDC light traps for four consecutive days. The traps were set into the houses and in peridomestic areas totaling 54 traps. A number of 3871 sand fly specimens of the genera Lutzomyia and Brumptomyia were collected. Sixty eight percent of the specimens were L. longipalpis and 16% L. whitmani, insect vectors of visceral and American cutaneous leishmaniasis, respectively. Environmental factors such as temperature, humidity, and frequency of precipitation suggest that the number of insects increases after rainy periods. During the same period mentioned above, seasonal captures were carried out in parks and green areas of Belo Horizonte, using Shannon trap.

Full Text Available O artigo faz uma abordagem alternativa utilizando como estudo a economia urbana heterodoxa a qual busca explicar de que modo surge a regularidade da configuração residencial urbana a partir da ação dos indivíduos no mercado. Utiliza-se o modelo de preços hedônicos para estimar o custo da violência - homicídios e roubos a transeuntes - implícito no preço dos imóveis residenciais, a partir de uma amostra com imóveis transacionados em Belo Horizonte. Duas regressões foram rodadas para que pudessem captar a disposição a pagar dos indivíduos para residirem em regiões de maior segurança. Os resultados demonstram que há relação entre redução nas taxas de criminalidade e valorização dos imóveis em algumas regiões de Belo Horizonte.This article provides an alternative approach, using the heterodox urban economy as a study object. Such economy seeks to explain how there is the regularity of the urban residential setting from the action of individuals in the market. The hedonic price model is used to esteem the implicit violence costs (e.g. homicides and robberies to pedestrians in housing prices, from a sample of properties transacted in Belo Horizonte. Two regressions that could capture the willingness of individuals to pay for living in regions with greater security were shot. The results show that there is a relationship between the reduction in crime rates and valuation of properties in some Belo Horizonte regions.

The aim of this paper is to present a synthesis of the geologic evolution in the Belo Horizonte Sheet comprising an area about 281.210 Km 2 . Rb-Sr and K-Ar isotope dating methods are used for age estimation of geologic deposits. The geologic evolution of the cratonic area is reflected by a stable central nucleus surrounded by marginal orogenic belts. In the central area were recognized greenstone belts structures involved by granite terrains and bordered by a granulitic region. The framework of the Sao Francisco Craton involves events of metamorphism, granitogenesis, sedimentary, volcanism and plutonism developed in the Early to Late Proterozoic. The stratigraphic column is complemented by Late Jurassic-Early Cretaceous continental deposits belonging to Parana-Basin. (M.V.M.)

O estudo foi desenvolvido em duas etapas: uma análise quantitativa por meio do método Grade of Membership (GoM, buscando delinear perfis de mulheres de 18 a 59 anos, que realizaram e não realizaram a consulta ginecológica nos 12 meses anteriores à pesquisa; e uma análise qualitativa, com base em 33 entrevistas semi-estruturadas, buscando captar a percepção que mulheres com características similares aos perfis extremos delineados na primeira etapa tinham sobre a consulta ginecológica. Os dados quantitativos são oriundos da pesquisa SRSR (Saúde Reprodutiva, Sexualidade e Raça/cor, realizada pelo Cedeplar em 2002. Já os dados qualitativos são provenientes da pesquisa "Aspectos quantitativos e qualitativos acerca do acesso à contracepção e ao diagnóstico e tratamento do câncer de colo uterino: uma proposta de análise para o município de Belo Horizonte, MG", ocorrida entre 2005 e 2006. Os resultados quantitativos sugerem que a realização de uma consulta ginecológica está muito relacionada às características socioeconômicas e demográficas das entrevistadas. Nota-se, também, que as mulheres com maior probabilidade de terem ido ao ginecologista, nos últimos 12 meses, são aquelas que tiveram um acompanhamento ginecológico regular e que costumavam procurar este profissional por meio de consultas particulares ou planos de saúde. Os resultados qualitativos reafirmam o desconforto das mulheres diante da consulta, sendo maior entre aquelas com menos escolaridade. Notou-se também que a primeira consulta ginecológica ocorreu em momentos muito diferentes para as mulheres de alta e de baixa escolaridade - para as primeiras está geralmente relacionada ao início da vida sexual e ao uso de contracepção, enquanto para

A carne suína in natura é consumida até três vezes por semana pela maioria da população (61,6%, em função de seu sabor e versatilidade. A compra costuma ser feita num mesmo estabelecimento comercial, sendo preferidos os cortes feitos na hora. O consumo de derivados da carne suína é maior que o da carne in natura em razão da grande variedade de produtos. Os consumidores acreditam que a carne suína in natura e derivados sejam perigosos à saúde pelo excesso de gordura ou de colesterol (38,4% e por transmitir doenças (27,8%. Sexo, idade e renda familiar têm influência no consumo, mas não escolaridade e ocupação. As marcas dos produtos derivados aumentam a confiabilidade e indicam a origem, para a maioria dos consumidores. A população, embora mais atenta aos conceitos de alimentação saudável e segura, não conhece o significado e a função da rastreabilidade e certificação de origem dos produtos.

The fundamental importance of human resources for the development of health care systems is recognized the world over. Health districts, which constitute the middle level of the municipal health care system in the city of Belo Horizonte, Brazil, deal with demands from all parts of the system. This research seeks to provide the essential features required in order to understand the phenomenon of increase in precarity of employment in these health districts. The legal and human resource management documents used by the Municipal Health Secretariat of the City of Belo Horizonte were adopted as the corpus for this research. In order to analyse the changes in employment (2002-2006), the data were collected from ArteRH, a computerized database dealing specifically with data related to human resources, which began operating in 2001. The workers were classified into permanent and non-permanent groups, and their contractual rights were described. Employment dynamics and changes were examined, concentrating on the incorporation of workers and on their social and employment rights during the period under study. The comparative data for the two groups obtained were presented in frequency distribution tables according to type of employment, sex, age group, level of education and wages from 2002 to 2006. There was a clear difference between the permanent worker and non-permanent worker groups as regards existing guaranteed employment rights and social security. The increase in the number of non-permanent workers in the workforce, the growing proportion of older workers among the permanently employed and the real wage reductions during the period from 2002 to 2006 are indicative of the process of growing precarity of employment in the group studied.

Full Text Available O advento da República envolveu Minas Gerais em uma experiência inédita em seus domínios, na última década dos Oitocentos. Em apenas seis anos, protagonistas diversos participaram de eventos marcantes, em torno da construção de uma nova capital, que redefiniram lugares de sociabilidade e modos de viver. Nascia Belo Horizonte, planejada e construída para ser a capital das Minas Gerais, vitrine da República, com suas praças, ruas e avenidas projetadas a régua e compasso. A pretensão era obrigar seus habitantes, antigos e novos, a "nascer de novo" com ela, como a poesia de Drummond de Andrade sintetiza. É em meio a tantas e tais vicissitudes que procuramos examinar, em diferentes espaços de sociabilidade urbana da nova capital, dispositivos de natureza diversa que encontravam no corpo o seu destino, como lugar de uma educação, de um cultivo, de uma civilização.The advent of the Republic in the last decade of 1800 was to Minas Gerais state a significant experience. In only six years, several protagonists were involved in remarkable events related to the building of the new capital city, which redefined the places for socialization and different lifestyles. The city of Belo Horizonte was born, planned and built to become the capital of Minas Gerais, a model for the Republic, with its squares, streets and avenues accurately projected with 'rulers and compass'. The main purpose was to make its old and new dwellers 'be born again' with Belo Horizonte, as later summed up in Drummond de Andrade's poem. Based on these aspects, our study focused on examining in different places of urban socialization provided by the new capital city different devices that found in people's bodies their destination, as a place for education, cultivation and civilization.

A causa anteparto contribuiu com 30% dos óbitos e 25% destas crianças tinham peso maior que 2.500g. Observou-se ainda a ocorrência de óbitos perinatais fora do hospital e óbitos de crianças cujas mães chegaram à maternidade já em período expulsivo. Cerca de 40% dos óbitos perinatais e 60% dos óbitos neonatais poderiam ter sido evitados. Estas mortes precoces sugerem falhas na assistência à gestante e ao recém-nascido no município, tanto no atendimento clínico como na organização da rede assistencial, sendo necessário avançar na qualificação e responsabilização dos serviços e do sistema de saúde como um todo sobre esta população.The perinatal mortality rate is still high in Belo Horizonte. This study investigated all 826 perinatal deaths taking place in 1999, focusing on the possibility of their prevention, using the Wigglesworth classification. The perinatal mortality rate was 20.2 per one thousand births, and the risk of perinatal death was 20 times higher in children with low birthweight. Some 24.6% of the children weighed more than 2,500g, and the main cause of death in this group was asphyxia during labor. The antepartum cause of death contributed to 30% of all deaths, and 25% of these children weighed more than 2,500g. Some deaths occurred out of hospital, and in some cases the mother arrived at hospital in end-stage labor. About 40% of all perinatal

Three-dimensional pressure distributions of oil flow in a reservoir with horizontal well were derived, and a new formula to calculate pressure drop along the horizontal wellbore was developed based on the principle of conservation of matter and momentum. The formula considers the effect of influx into the horizontal wellbore from the reservoir on pressure drop in the wellbore. A mathematical model to couple fluid flow in the reservoir with flow in the horizontal wellbore is presented. Model results and experimental data showed good correspondence. Results showed the influence of pressure drop on well performance. 13 refs., 2 tabs., 7 figs.

Widespread questions have been raised concerning the quality of services provided at birthing centers by obstetric nurses. The results of the current study were: 11.4% maternal transfer rate; 2.2% cesarean sections; 1.2% neonatal ICU admissions; and 1% 5-minute Apgar scores below 7. Delivery dystocia and the request for epidural anesthesia were the main reasons for maternal transfer, and respiratory distress was the main cause of neonatal ICU admission. Corrected neonatal mortality was 2 per 1,000 live births. The results at this birthing center did not differ significantly from those in a review of the international literature. The most striking finding was the low cesarean rate. Comparative studies and more comprehensive national data on low-risk gestations are needed.

Thus, the formation of the political agenda, the Political Pedagogical Project Program and the Strategic Plan 2010-2030 BH were investigated. The policy context is not organized in a linear fashion; it is a process of groups of interest interaction. With the discourse of coping with school failure, revealed by the students’ yield and flow evaluation indices (approval, repetition and dropout, the Integrated School education documents announce education and leisure as forms of production, strengthening links between public and private. The right to education is restricted to children’s and youth’s access and permanence in school without creating a perspective of universalization and quality. The documents address the leisure with a simplistic view of construction and maintenance of equipment and the idea of activity

In this work soil samples, iron ore and airborne atmospheric particulate matter (PM) in the Metropolitan Region of Belo Horizonte (MRBH), State of Minas Gerais, Brazil, are investigated with the aim of identifying if the sources of the particulate matter are of natural origin, such as, resuspension of particles from soil, or due to anthropogenic origins from mining and processing of iron ore. Samples were characterized by powder X-ray diffraction, X-ray fluorescence and 57 Fe-Moessbauer spectroscopy. The results showed that soil samples studied are rich in quartz and have low contents of iron mainly iron oxide with low crystallinity. The samples of iron ore and PM have high concentration of iron, predominantly well crystallized hematite. 57 Fe-Moessbauer spectroscopy confirmed the presence of similar iron oxides in samples of PM and in the samples of iron ore, indicating the anthropogenic origin in the material present in atmosphere of the study area.

Sand flies were sampled at 15-day intervals in three residences, in each of which two CDC light traps were installed, one indoors and the other in the peridomicile. A total of 397 sand flies were captured in the three areas, with 65%, 30% and 1% of specimens collected in the eastern, northeast and Barreiro districts, respectively. The overall proportions of sand flies collected inside and around the houses were similar (57% vs 43% and this pattern was seen for both Lutzomyia longipalpis and Lutzomyia whitmani . The highest population levels during the two years of the study were from October to March. From October onwards, numbers increased constantly until February. A gradual fall was seen from April onwards until the lowest levels were reached in the months of June, July and August.

The objective of this study was to examine the association between individual satisfaction with social and physical surroundings and the habit of smoking cigarettes. Data from the Health Survey of Adults from the metropolitan area of Belo Horizonte, Minas Gerais, Brazil, were used. Based on a probability sample, participants (n = 12,299) were selected among residents aged 20 years old or more. The response variable was the smoking habit and the explanatory variable of interest was the neighborhood perception. Potential confounding variables included demographic characteristics, health behaviors and other indicators of socioeconomic position. The prevalence of current smokers, former smokers and never smokers were 20.8, 14.1 and 65.1%, respectively; 74.4 and 25.5% of the participants were categorized as being more satisfied and less satisfied with the neighborhood, respectively. Compared to those who never smoked, former smokers (adjusted odds ratio = 1.40, 95% confidence interval 1.20 - 1.62) and current smokers (adjusted odds ratio = 1.17, 95% confidence interval 1.03 - 1.34) were less satisfied with the neighborhood compared to those who never smoked. The results of this study indicate there is an independent association between the smoking habit and a less satisfying neighborhood perception in the metropolitan region of Belo Horizonte, which does not depend on individual characteristics, traditionally reported as being associated with smoking.

Health personnel are key players in developing and improving healthcare systems, caring for individuals and their communities, and helping improve quality of life. However, these professionals are often exposed to long working hours because of the pressing need for their services at potentially any time of day. The long working hours they endure are a major risk factor for both acute and chronic health problems. The present study aimed to analyze occurrences of long working hours and their association with individual characteristics and employment factors among workers in the municipal healthcare system in Belo Horizonte, Brazil. In this cross-sectional study, a ramdomly selected proportional sample of 1549 participants was analyzed from among the total of 13 602 workers in the Belo Horizonte municipal healthcare system in 2009. "Long" working hours were defined as >44 h/week. A self-administered questionnaire was used for accumulating data.

An urban heat island in tropical area investigated by remote sensing: Belo Horizonte City

The inappropriate urbanization process in tropical areas causes local climatic alterations forming heat islands over the cities. In order to guide urban planning in the control of the environmental urban quality, as for the thermal comfort is concerned, it has developed a method to evaluate the thermal behavior of built and urban green areas. Two TM-LANDSAT images from Belo Horizonte City, the study area, were chosen based on summer and winter typical days statistically characterized. Bands 3 and 4 of these images were combined to produce a local vegetation index map. Band 6 was used to observe the warmer and cooler areas in the city. Some heat nucleons were identified through data analysis of remote sensing, meteorological and urban land use. The mean maximum temperature of the principal heat nuclei exceeds, in summer, the limit value of diurnal thermal comfort for the city climate, using Givoni's Bioclimatic Chart. During the day period, the areas with a lower vegetation index, more density and predominating horizontal settlements were the most warmer. The cooling effect of urban green areas was very local. Thus, it should be regularly distributed in the built areas. The limits of occupation density and edification could be fixed, too, considering its impacts on the urban thermal environment

One pharmacy was responsible for 39.8% of the pharmaceutical sales. During the second stage, 14,554 sales records from this "blockbuster" pharmacy were analyzed, from April to August 2005; 9.2% of sales were for anorexigenic products, 91.8% of which prescribed in association with another substance. The data suggest irrational use of anorexigenic drugs by these consumers and highlight the need for proper regulation of these products. It is important to understand both the role of pharmacies in this regulation and that of physicians in the rational use of these substances.

Drivers and conductors working in public transport are frequently exposed to inadequate working conditions and consequently to health problems relating to their work activities. This study investigates the relationship between the working conditions of drivers and conductors in the Metropolitan Region of Belo Horizonte and their perception of health-related quality of life. Health-related quality of life was measured in a sample of 1,607 public transport workers in the city of Belo Horizonte using the SF-12 (Medical Outcomes Study Short-Form General Health Survey). The presence and magnitude of independent associations between the SF-12 domains and the exposure variables were determined by means of odds ratios obtained through logistic regression. After adjustments, the PCS (Physical Component Score) was found to be negatively associated with the existence of breaks during the working day and positively associated with unavailability of technical resources for meeting needs. The MCS (Mental Component Score) was positively associated with being female, having two or more medical diagnoses of illnesses, absenteeism and recent episodes of aggression or threats, and feeling vibration in the whole body. The MCS was negatively associated with the practice of physical exercise. Both components were negatively associated with older age and positively associated with having a poor self-assessment of health. Exposure to a variety of risk factors while performing work worsened health-related quality of life. The results obtained may provide support for rethinking and guiding public policies directed towards metropolitan populations.

Full Text Available The present article describes the occurrence of 17 cases of acute schistosomiasis in the metropolitan area of Belo Horizonte, state of Minas Gerais, Brazil. All individuals affected took a bath in a swimming pool of a holiday resort that was provided with water from a nearby brook. The apparently clean water and the absence of snails in the pool gave the wrong impression that there was no risk for infection. During a malacological survey at the site snails of the species Biomphalaria glabrata were found and tested positive for Schistosoma mansoni. All the patients live in the middle-class area of Barreiro, metropolitan area of Belo Horizonte and have medium grade school education. The difficulties in establishing the right diagnosis is expressed by the search for medical attention in 17 different medical facilities, the wide range of laboratory test and the inadequate treatment administration. A lack of knowledge about the disease was found in all groups studied. The booming rural tourism in endemic areas is identified as a probable risk factor for infection, especially for individuals of the non-immune middle and upper class parts of the society in urban centers. Special attention is given to a multidisciplinary approach to the complex issue of disease control and prevention.

Production forecasting and economic evaluation of horizontal wells completed in natural fractured reservoirs

1996-01-01

A technique for optimizing recovery of hydrocarbons from naturally fractured reservoirs using horizontal well technology was proposed. The technique combines inflow performance analysis, production forecasting and economic considerations, and is based on material balance analysis and linear approximations of reservoir fluid properties as functions of reservoir pressure. An economic evaluation model accounting for the time value of cash flow, interest and inflation rates, is part of the package. Examples of using the technique have been demonstrated. The method is also applied to a gas well producing from a horizontal wellbore intersecting discrete natural fractures. 11 refs., 2 tabs,. 10 figs

The organization of public clinical laboratories is experiencing changes without, however, an organizational assessment of its effectiveness. The study aimed to determine a parameter of effectiveness for public clinical laboratories of Belo Horizonte, Minas Gerais State, and set cut-off points for the sections of these laboratories. In order to do so, the total production and number of hours worked during a period of 7 months in the year 2008 were consolidated. Due to the entrance of the workers in the mode of production in the laboratories network, it could be observed a variability regarding the performance of these workers. The effectiveness parameter of the network was established in 29.90 tests per hour. As a consequence of this first analysis, the cut-off points are: 15.50 for the hematology section; 67.29 for chemistry; 6.45 for parasitology; 11.35 for urinalysis; 4.94 for microbiology and 19.03 for immunology. From these results, it was concluded that the working process in laboratories can generate a decrease in effectiveness.

This paper presented a new flooding scheme for single horizontal wells that could improve recovery from thin marginal heavy oil reservoirs or from offshore reservoirs. The scheme involved the use of a multiple tubing string completion in a single wellbore. Special packers were installed within the long completion horizontal interval to establish an injection zone and a production zone. The new flooding scheme also involved simultaneous injection and production. Numerical simulation of the reservoir was used to determine the thickness of the formation and the lower limitation for different viscosities and the optimum time to start steam flooding after steam soaking by economic oil/steam ratio. The peak recovery efficiency of steam flooding was shown to occur when the length of separation section ratio is 0.15 to 0.2. It was concluded that high thermal efficiency in horizontal wells with long completion intervals can be maintained by alternating between steam soaking and steam flooding. Suitable alternation time to steam flooding is a seventh cycle for horizontal wells. Water cut and pressure difference will increase the steam injection rate, and thereby improve the oil production rate. The suitable injection rate for steam flooding is 2.4 t/d.ha.h because of its slow pressure change. 11 refs., 7 figs.

The Role of Horizontal Wells when Developing Low-Permeable, Heterogeneous Reservoirs

Full Text Available The widespread use of horizontal drilling in recent years has shown that horizontal wells can be successfully used both at the initial and late stages of development. This is due to the fact that horizontal wells, in contrast to vertical wells, contact a larger area of ​​the productive formation, while the surface of drainage of the oil-saturated layer, productivity of the wells due to the formation of cracks, and also the influence on thin layers increases. One of the methods of impact on the reservoir is the steam-thermal method. The main advantage of the use of the heat wave method in horizontal wells is a significant increase in the well production rate, a decrease in the water cut of the reservoir, a decrease in the oil viscosity, an increase in the injectivity of the injection well, and an increase in the inflow in producing wells. As a result of the total effect, a significant increase in production is obtained throughout the entire deposit. Enhanced oil recovery from the injection of steam is achieved by reducing the viscosity of oil, covering the reservoir with steam, distilling oil and extracting with a solvent. All this increases the displacement coefficient. One of the most effective ways to increase oil recovery at a late stage of field operation is sidetracking in emergency, highly watered and low-productive wells. This leads to the development of residual reserves in weakly drained zones of reservoirs with a substantial increase in well productivity in low-permeable reservoirs. This approach assumes that the initial drilling of wells is a ‘pilot’ stage, which precedes the development of oil reserves in the late stages of deposit development. In the fields of Western Siberia, multiple hydraulic fracturing of the reservoir has been improved due to a special stinger in the liner hanger of multi-packer installation, which excludes the influence of high pressures on the production column under the multiple hydraulic fracturing

This was a cross-sectional study of 310 patients enrolled in two public health centers in Belo Horizonte, Minas Gerais State, Brazil. Delayed ART initiation was defined as starting treatment with a CD4 count lower than 200 cells/mm³ or clinical symptoms of severe immunodepression at the time of first antiretroviral prescription. The majority of participants were males (63.9%, had no health insurance (76.1%, and started ART less than 120 days after the first medical visit (75.2%. The proportion of delayed ART initiation was 68.4%. Unemployment, referral by a health professional for HIV testing, fewer than two medical visits in the six months prior to ART initiation, and time between first medical visit and ART initiation less than 120 days were independently associated with the outcome. Our results suggest that every patient 13 to 64 years of age should be offered HIV testing, which could increase the rate of early HIV diagnosis, and thus patients that tested positive could benefit from timely follow-up and antiretroviral therapy.

Reservoir simulation with MUFITS code: Extension for double porosity reservoirs and flows in horizontal wells

Afanasyev, Andrey

2017-04-01

Numerical modelling of multiphase flows in porous medium is necessary in many applications concerning subsurface utilization. An incomplete list of those applications includes oil and gas fields exploration, underground carbon dioxide storage and geothermal energy production. The numerical simulations are conducted using complicated computer programs called reservoir simulators. A robust simulator should include a wide range of modelling options covering various exploration techniques, rock and fluid properties, and geological settings. In this work we present a recent development of new options in MUFITS code [1]. The first option concerns modelling of multiphase flows in double-porosity double-permeability reservoirs. We describe internal representation of reservoir models in MUFITS, which are constructed as a 3D graph of grid blocks, pipe segments, interfaces, etc. In case of double porosity reservoir, two linked nodes of the graph correspond to a grid cell. We simulate the 6th SPE comparative problem [2] and a five-spot geothermal production problem to validate the option. The second option concerns modelling of flows in porous medium coupled with flows in horizontal wells that are represented in the 3D graph as a sequence of pipe segments linked with pipe junctions. The well completions link the pipe segments with reservoir. The hydraulics in the wellbore, i.e. the frictional pressure drop, is calculated in accordance with Haaland's formula. We validate the option against the 7th SPE comparative problem [3]. We acknowledge financial support by the Russian Foundation for Basic Research (project No RFBR-15-31-20585).

Full Text Available Trata-se de um estudo de caso qualitativo que discute o trabalho no contexto do Sistema único de saúde e como seus princípios se operam no cotidiano dos serviços que compõem sua rede hierarquizada. Objetivou compreender integralidade, equidade e resolutividade nas ações cotidianas de gestores e profissionais de saúde em Belo Horizonte-MG. Constatou-se que "cuidado como fazer cotidiano" e "acolhimento, vínculo e acesso" foram temas incorporados pelos profissionais no desenvolvimento do seu trabalho. A partir dos resultados, percebeu-se uma interposição das situações de urgência e emergência em detrimento das atividades programadas. Além disso, a administração desse processo de trabalho é direcionada pelo conhecimento técnico-estruturado interferindo na qualidade da assistência à saúde. Nesse sentido, o processo de produção do cuidado deve ser pensado em seu microespaço, ressaltando-se o acolhimento, o estabelecimento de vínculo e a responsabilização no sentido de se garantir uma rede de cuidados pertinente e acessível àqueles que necessitem transitar por ela. É preciso que se eliminem as fragmentações presentes tanto na forma de organização dos serviços de saúde quanto nas práticas cotidianas dos profissionais, para se oferecer uma assistência integral, resolutiva e para se humanizarem essas práticas, visando sempre à qualidade de vida da população e à saúde enquanto direito de cidadania.This is a qualitative case study which discusses the work in the context of the Unified Health System and how its principles occur in the daily services within its stratified network.

Demographic, occupational and psychosocial characteristics affect the health and occupational performance of workers. The objective of the present study was to elaborate a profile of the work ability and factors that affect it in a bus transportation company in Belo Horizonte, Brazil. The instruments used included a socio-demographic and occupational questionnaire, the Work Ability Index and the Job Stress Scale. Demographic information revealed that 85.7% of the 126 employees of the company were active workers, 98% were males, with an average of 39 years of age (SD= 10) and 79 months working in the company (SD= 68); more than half reported having a low schooling level. In terms of personal habits, 88% were exposed to one or more risk factors, especially a sedentary lifestyle. The average strain value (as a consequence of stress) was 0.78 (SD= 0.2) and 75.3% reported episodes of violence at the workplace. The work ability was good to excellent among 89% of the workers. Results from the logistic regression analysis showed that strain was the only significant variable in relation to the Work Ability Index, (estimated odds ratio of 0.02). The results suggest that psychosocial factors presented the greatest association with work ability, and preventive and/or corrective measures should be implemented.

2017-10-01

As more urban solid waste is generated, managing it becomes ever more challenging and the potential impacts on the environment and human health also become greater. Handling waste - including collection, treatment and final disposal - entails risks of work accidents. This article assesses the perception of waste management workers regarding work-related accidents in domestic and health service contexts in Belo Horizonte, Brazil. These perceptions are compared with national data from the Ministry of Social Security on accidents involving workers in solid waste management. A high proportion of accidents involves cuts and puncture injuries; 53.9% among workers exposed to domestic waste and 75% among those exposed to health service waste. Muscular lesions and fractures accounted for 25.7% and 12.5% of accidents, respectively. Data from the Ministry of Social Security diverge from the local survey results, presumably owing to under-reporting, which is frequent in this sector. Greater commitment is needed from managers and supervisory entities to ensure that effective measures are taken to protect workers' health and quality of life. Moreover, workers should defend their right to demand an accurate registry of accidents to complement monitoring performed by health professionals trained in risk identification. This would contribute to the improved recovery of injured workers and would require managers in waste management to prepare effective preventive action.

Full Text Available Rotavirus has been considered the main agent of infectious diarrhea especially among younger children. We addressed the prevalence of rotavirus-associated diarrhea and the diversity of circulating electropherotypes by immunochromatography and RNA electrophoresis. Stool samples were taken from 391 children (267 with diarrhea from the lower socioeconomic stratum who sought treatment in the Hospital Infantil João Paulo II/Belo Horizonte, during 2005 and 2006. Rotavirus was detected in 79/20.2% of subjects, 64/24.0% with diarrhea and 15/12.1% with no diarrhea. The virus was strongly associated with diarrhea (p = 0.003. A total of 76/19.4% and 69/17.6% rotavirus-positive children were identified by immunochromatography and electrophoresis, respectively. Rotavirus-associated diarrhea was more frequently detected in dry months (p < 0.001 and almost exclusively in children aged up to three years. Long profile strains prevailed (54/78.3% but a shift toward short electropherotype was identified. Despite the decrease seen in 2006, rotavirus infection is still very common in our area. Although viral RNA electrophoresis is useful as a typing method, it should not be used exclusively in the diagnosis of rotavirus infection. We confirmed a shift from long to short profile strains, as already described for other South American countries.

Angiographic and autopsy studies suggest that between 0.5% and 5% of the population have intracranial aneurysms. Approximately 30000 people suffer aneurysmal subarachnoid hemorrhage in the United States each year, and 60% die or are left permanently disabled. We report our experience in the surgical treatment of intracranial aneurysms in a six year period, in Belo Horizonte, Minas Gerais, Brazil. We reviewed the hospital files, surgical and out-patient notes of all patients operated on for the treatment of intracranial aneurysms from January 1997 to January 2003. Four hundred and seventy-seven patients were submitted to 525 craniotomies for treatment of 630 intracranial aneurysms. The majority of patients were female (72.1% in the fourth or fifth decade of life. Anterior circulation aneurysms were more common (94.4%. The most common location for the aneurysm was the middle cerebral artery bifurcation. The patients were followed by a period from 1 month to 5 years. The outcome was measured by the Glasgow Outcome Scale (GOS. At discharge, 62.1% of the patients were classified as GOS 5, 13.9% as GOS 4, 8.7% as GOS 3, 1.7% as GOS 2 and 14.8% as GOS 1.A hemorragia subaracnóidea espontânea é responsável por cerca de 5 a 10% de todos os acidentes vasculares cerebrais, com uma incidência mundial de 10,5 / 100000 pessoas/ano, variando em estudos individuais de 1,1 a 96 / 100000 pessoas / ano, de acordo com diferenças étnicas e geográficas.

- Medical literature has shown dyspepsia and heartburn-related symptoms occur among 15% to 40% of the population. These symptoms can occur at any age and are more prevalent in women. - Investigate the prevalence of dyspeptic symptoms and heartburn among individuals over 18. - Individuals over 18 were randomly selected in public venues in Belo Horizonte/MG to participate. A standardized questionnaire that included questions related to social-demographic characteristics, eating habits, digestive symptoms, medical appointments, medications, exams, previous surgeries and comorbidities was applied. A questionnaire about functional dyspepsia diagnosis (Rome III) was also applied. - A total of 548 individuals were interviewed. Among these, 58.4% were women, 59.3% were white, 55.9% were single and the average age was 36 years. Within this group, 376 individuals (68.6%) declared to have some symptom and/or use medication to relieve dyspepsia symptoms, and for these patients were applied the Rome III questionnaire. Based on the diagnostic criteria for the questionnaire proposed by the Rome III consensus, the symptom of postprandial fullness was reported by 6.7% of the individuals, early satiety (3.5%) and epigastric pain (10.6%). The overlap of these symptoms was very frequent. The prevalence of functional dyspepsia was 10.6% (postprandial discomfort syndrome (8.2%) and epigastric pain syndrome (2.4%). Among all participants, 52.5% reported heartburn, and 11.1% presented this symptom at least once a week. The most used drug was omeprazole. - The prevalence of dyspeptic symptoms and heartburn among a Brazilian adult urban population is similar to those described in other countries.

Full Text Available Project Horizonte, an open cohort of homosexual and bisexual human immunodeficiency virus (HIV-1 negative men, is a component of the AIDS Vaccine Program, in Belo Horizonte, Minas Gerais, Brazil. The objective of this study was to compare volunteers testing HIV positive at cohort entry with a sample of those who tested HIV negative in order to identify risk factors for prevalent HIV infection, in a population being screened for enrollment at Project Horizonte. A nested case-control study was conducted. HIV positive volunteers at entry (cases were matched by age and admission date to three HIV negative controls each. Selected variables used for the current analysis included demographic factors, sexual behavior and other risk factors for HIV infection. During the study period (1994-2001, among the 621 volunteers screened, 61 tested positive for HIV. Cases were matched to 183 HIV negative control subjects. After adjustments, the main risk factors associated with HIV infection were unprotected sex with an occasional partners, OR = 3.7 (CI 95% 1.3-10.6, receptive anal intercourse with an occasional partner, OR = 2.8 (95% CI 0.9-8.9 and belonging to the negro racial group, OR = 3.4 (CI 95% 1.1-11.9. These variables were associated with an increase in the risk of HIV infection among men who have sex with men at the screening for admission to an open HIV negative cohort.

Human beings are exposed to ionizing radiation from many natural sources. Radon and its progeny have been recognized as the most important contributors to the natural radioactivity dose, accounting for about half of all human exposure to ionizing radiation. Radon ( 222 Rn) is a α-radioactive noble gas derived from the natural series of uranium (2 38 U), which occurs in a wide concentration range in all geological materials, especially, in rocks, soils and waters. By diffusion and convection, radon migrates from the rocks and soils to atmosphere and through fissures, pipes and holes it may enter the dwellings and other buildings. Another important radon source in dwellings is its emanation from the construction material. The radon progeny concentration in dwellings has been receiving considerable global attention due to its potential effect in causing lung cancer if it deposited in upper respiratory tract when inhaled. This paper presents radon concentration distribution in dwellings in Metropolitan Region of Belo Horizonte - RMBH. The effective dose estimate is also presented for the RMBH inhabitants. The geological settings of the area are Archean rocks of Granitic Gnaissic Complex and of metasediments sequences of the great Precambrian unit of the Iron Quadrangle of Minas Gerais, Brazil. Radon concentration measurements were carried out with continuous detector AlphaGUARD PQ200PRO (Genitron), in passive mode and with passive detectors E-PERM R Eletret Ion Chamber-EIC. The radon progeny concentration was carried out with a solid state alpha spectroscope, the DOSEman PRO (Sarad). It was found an indoor radon concentration varying in a large range from 18.5 to 2671.4 Bq/m -3 , with an average value of 148.0 Bqm -3 and geometric mean equal to 128.2 Bqm -3 . The variable results are due mainly to region geological factors and building material composition of dwellings. The equilibrium factor between radon and its progeny were determined in dwellings, as 0.3 in

Full Text Available The serological profile of seropositive dogs according to anti-Leptospira agglutinins was checked in Belo Horizonte including variables such as race, sex, age and whether the dog had an owner or not. The dogs were captured by the Zoonosis Control Center in nine neighborhoods around the city and were separated in two categories - with owners or captured on the streets. The prevalence of anti-Leptospira agglutinins was evaluated in 3,417 blood samples using the microscopic agglutination test (MAT from September 2001 to September 2002. It was found that 13.1% of the dogs had seropositive results with the most reactive serovars being Canicola (7.0%, Ballum (6.1%, Pyrogenes (3.2% and Icterohaemorrhagiae (2.9%. The prevalence of other serovars was less than 1.0%. Greater prevalence was found in male, crossbred dogs, without owners. There were no significant results due to age in 95% (P=0.808 of the cases. According to the results, more research should be done in order to isolate and classify the serovars in positive dogs, especially Ballum and Pyrogenes, which will suggest their inclusion in the commercial vaccines against leptospira used in dogs in this city.

The data from the project 'Conviver,' launched in 2006 in Belo Horizonte (Brazil), provides a unique opportunity to study illegal electricity connections. Based on an original dataset of 15,279 low-income households, this paper studies the incidence and determinants of illegality in the context of low-income urban favelas. The probability of engaging in illegal behavior is explained not just by low income, but by a combination of concurring factors: sub-standard energy provision and equipment; inefficient/incorrect use of domestic electric appliances and running an informal in-house business. These recurrent issues in the urban favelas aggravate a sense of exclusion from growth, which is generally recognized as a trigger of illegality. The impact of energy demand on energy-related illegality is carefully analyzed, and different empirical strategies adopted to circumvent some simultaneity problem between both decision processes. The effectiveness of consumption-based energy subsidies is also explored. In spite of some contrary arguments in the literature, in the context of peri-urban slums, such measures may exert a positive impact in mitigating illegal access and use of energy. Effectiveness will be enhanced by accompanying measures such as: perceivable improvements of equipment, metering and maintenance, promotion of beneficiaries' awareness of energy usage, and energy-saving behaviors.

Full Text Available A cidade tem sido encarada tradicionalmente na Administração sob a ótica funcionalista, ao ser entendida como campo de atuação profissional ou objeto da administração pública e gestão urbana. Todavia, estudos que versam sobre a urbes em uma perspectiva não-funcionalista tem se tornado cada vez mais recorrente, principalmente, a partir de uma visão que focaliza a complexidade urbana e evoca a vida social organizada de indivíduos e grupos oprimidos em diversos âmbitos sociais. Neste artigo buscamos analisar os discursos que orientam práticas organizativas relacionadas à pichação em Belo Horizonte, o que foi feito mediante um estudo qualitativo baseado em análise do discurso. Além de pesquisa em documentos oficiais sobre as ações governamentais no combate à pichação, foram efetuadas entrevistas individuais em profundidade com nove sujeitos, entre gestores públicos municipais responsáveis pelo combate à pichação, indivíduos da sociedade civil participantes das ações do projeto municipal, e representantes da pichação belo horizontina. O tratamento dos dados foi efetuado por meio da análise do discurso francesa, pela qual se buscou a identificação e análise de aspectos e elementos discursivos segundo roteiro constituído por: i seleções lexicais; ii percursos semânticos; iii interdiscursividades; iv discursos principais; v reflexão e refração linguísticas; vi aspectos ideológicos combatidos e defendidos; e vii posicionamentos discursivos em relação aos discursos hegemônicos na sociedade. Os principais resultados sugerem que o governo da cidade tanto orienta as representações de combate à pichação como é pressionado para enfrentar o fenômeno segundo os vários modos de fazer, pelos quais imperam os instrumentos de controle sobre as práticas de organização da cidade e se instituem agentes sociourbanos de legitimação estratégica.

The main sources of radon concentration in buildings are the underground surrounding soil and bedrock, construction materials and underground water supply. However, the contribution from these sources to the indoor radon level depends on many factors, such as type of the building, geology and pedology of the site and also the floor level. Focusing on this concern, the present work outlines on the characterization of the radon concentration in two different kinds of buildings - slab-on-grade dwellings and apartments on the second floor and above - in the Metropolitan Region of Belo Horizonte, Brazil, which is located in a large part on granite embasement area, the Granitic Gnaissic Complex. The radon concentration in dwellings and apartments, measured by using E-PERM Electrets Ion Chamber, ranged from 18.5 to 1591.0 Bqm -3 (mean value 114.7 ± 5.5 Bqm -3 ) and 3.7 to 185.0 Bqm -3 (mean value 70.3 ± 6.7 Bqm -3 ), respectively. Thus, the highest radon concentration is present in dwellings not in apartments, suggesting that the enhanced radon concentration maybe was originated mainly from local geological settings instead of other sources. In order to confirm this hypothesis, the measurements of the soil gas radon concentration were carried out by using AlphaGUARD PQ2000PRO detector and 226 Ra ( 214 Bi) and 224 Ra ( 212 Pb) specific activity in construction materials were determined by using gamma-ray spectrometry HPGe detector. These results confirmed the local geological setting as the main radon source. Moreover, radon concentration much higher than United States Environmental Protection Agency USEPA action level 148Bq.m -3 occurred only in slab-on-grade dwellings. (author)

Full Text Available ABSTRACT BACKGROUND Medical literature has shown dyspepsia and heartburn-related symptoms occur among 15% to 40% of the population. These symptoms can occur at any age and are more prevalent in women. OBJECTIVE Investigate the prevalence of dyspeptic symptoms and heartburn among individuals over 18. METHODS Individuals over 18 were randomly selected in public venues in Belo Horizonte/MG to participate. A standardized questionnaire that included questions related to social-demographic characteristics, eating habits, digestive symptoms, medical appointments, medications, exams, previous surgeries and comorbidities was applied. A questionnaire about functional dyspepsia diagnosis (Rome III was also applied. RESULTS A total of 548 individuals were interviewed. Among these, 58.4% were women, 59.3% were white, 55.9% were single and the average age was 36 years. Within this group, 376 individuals (68.6% declared to have some symptom and/or use medication to relieve dyspepsia symptoms, and for these patients were applied the Rome III questionnaire. Based on the diagnostic criteria for the questionnaire proposed by the Rome III consensus, the symptom of postprandial fullness was reported by 6.7% of the individuals, early satiety (3.5% and epigastric pain (10.6%. The overlap of these symptoms was very frequent. The prevalence of functional dyspepsia was 10.6% (postprandial discomfort syndrome (8.2% and epigastric pain syndrome (2.4%. Among all participants, 52.5% reported heartburn, and 11.1% presented this symptom at least once a week. The most used drug was omeprazole. CONCLUSION The prevalence of dyspeptic symptoms and heartburn among a Brazilian adult urban population is similar to those described in other countries.

Full Text Available Introduction The aim of this study was to determine the antimicrobial susceptibility of Neisseria gonorrhoeae isolates obtained from patients attending a public referral center for sexually transmitted diseases and specialized care services (STD/SCS in Belo Horizonte, Brazil. Methods Between March 2011 and February 2012, 201 specimens of Neisseria gonorrhoeae were consecutively obtained from men with symptoms of urethritis and women with symptons of cervicitis or were obtained during their initial consultation. The strains were tested using the disk diffusion method, and the minimum inhibitory concentrations of azithromycin, cefixime, ceftriaxone, ciprofloxacin, chloramphenicol, penicillin, tetracycline and spectinomycin were determined using the E-test. Results The specimens were 100% sensitive to cefixime, ceftriaxone and spectinomycin and exhibited resistances of 4.5% (9/201, 21.4% (43/201, 11.9% (24/201, 22.4% (45/201 and 32.3% (65/201 to azithromycin, ciprofloxacin, chloramphenicol, penicillin and tetracycline, respectively. Intermediate sensitivities of 17.9% (36/201, 4% (8/201, 16.9% (34/201, 71.1% (143/201 and 22.9% (46/201 were observed for azithromycin, ciprofloxacin, chloramphenicol, penicillin and tetracycline, respectively. The specimens had plasmid-mediated resistance to penicillin PPNG 14.5% (29/201 and tetracycline TRNG 11.5% (23/201. Conclusions The high percentage of detected resistance to penicillin, tetracycline, chloramphenicol and ciprofloxacin indicates that these antibiotics are not appropriate for gonorrhea treatment at the Health Clinic and possibly in Belo Horizonte. The resistance and intermediate sensitivity of these isolates indicates that caution is recommended in the use of azithromycin and emphasizes the need to establish mechanisms for the surveillance of antimicrobial resistance for the effective control of gonorrhea.

As the platform-based horizontal well production mode has been widely applied in petroleum industry, building a reliable fine reservoir structure model by using horizontal well stratigraphic correlation has become very important. Horizontal wells usually extend between the upper and bottom boundaries of the target formation, with limited penetration points. Using these limited penetration points to conduct well deviation correction means the formation depth information obtained is not accurate, which makes it hard to build a fine structure model. In order to solve this problem, a method of fine reservoir structure modeling, based on 3D visualized stratigraphic correlation among horizontal wells, is proposed. This method can increase the accuracy when estimating the depth of the penetration points, and can also effectively predict the top and bottom interfaces in the horizontal penetrating section. Moreover, this method will greatly increase not only the number of points of depth data available, but also the accuracy of these data, which achieves the goal of building a reliable fine reservoir structure model by using the stratigraphic correlation among horizontal wells. Using this method, four 3D fine structure layer models have been successfully built of a specimen shale gas field with platform-based horizontal well production mode. The shale gas field is located to the east of Sichuan Basin, China; the successful application of the method has proven its feasibility and reliability.

Full Text Available As formas urbanas são decorrentes das alterações ambientais do lugar, ou seja, das suas condições físicas, biológicas e antrópicas, sendo a última a principal indutora de transformações. As cidades e suas paisagens alteram-se quando mudam as condições socioeconômicas e culturais, como ocorre em Belo Horizonte, capital de Minas Gerais, que se expande além de seus limites físicos e políticos, conurbando-se com os demais municípios da Região Metropolitana. As ocupações ocorrem desordenadamente, ocasionando problemas de gestão pública, saneamento, mobilidade, além de problemas de ordem ambiental. O presente trabalho aborda a área conurbada da Região Norte da Região Metropolitana de Belo Horizonte (RMBH, chamada de “Vetor Norte”, e sua relação com os espaços livres públicos existentes, através de análises qualitativas e quantitativas. Ainda que os espaços livres públicos sejam considerados como permanências no tecido urbano, os espaços edificados ampliam-se, respeitando ou não as legislações vigentes. A ocorrência maior deste conflito está localizada, principalmente, na área abordada, impulsionada pela construção da Linha Verde e de outros equipamentos, razão da sua escolha para o estudo. Através do conhecimento destes espaços, com base nas variáveis históricas e contemporâneas, será possível construir um referencial metodológico das relações entre os espaços livres públicos, os espaços edificados e a forma urbana. Os espaços livres podem ser considerados elementos estruturantes da forma da cidade, e de legítima importância para a qualidade de vida urbana.

Full Text Available The generally accomplished technique for horizontal wells in tight gas reservoirs is by multi-stage hydraulic fracturing, not to mention, the flow characteristics of a horizontal well with multiple transverse fractures are very intricate. Conventional methods, well as an evaluation unit, are difficult to accurately predict production capacity of each fracture and productivity differences between wells with a different number of fractures. Thus, a single fracture sets the minimum evaluation unit, matrix, fractures, and lateral wellbore model that are then combined integrally to approximate horizontal well with multiple transverse hydraulic fractures in tight gas reservoirs. This paper presents a new semi-analytical methodology for predicting the production capacity of a horizontal well with multiple transverse hydraulic fractures in tight gas reservoirs. Firstly, a mathematical flow model used as a medium, which is disturbed by finite conductivity vertical fractures and rectangular shaped boundaries, is established and explained by the Fourier integral transform. Then the idea of a single stage fracture analysis is incorporated to establish linear flow model within a single fracture with a variable rate. The Fredholm integral numerical solution is applicable for the fracture conductivity function. Finally, the pipe flow model along the lateral wellbore is adapted to couple multi-stages fracture mathematical models, and the equation group of predicting productivity of a multi-stage fractured horizontal well. The whole flow process from the matrix to bottom-hole and production interference between adjacent fractures is also established. Meanwhile, the corresponding iterative algorithm of the equations is given. In this case analysis, the productions of each well and fracture are calculated under the different bottom-hole flowing pressure, and this method also contributes to obtaining the distribution of pressure drop and production for every

Full Text Available OBJETIVO: Avaliar o impacto de programa de prevenção de homicídios. MÉTODOS: Com base nos dados do Programa Fica Vivo, de prevenção de homicídios, foi realizado um estudo quase experimental com análise de séries temporais da ocorrência de homicídios no aglomerado Morro das Pedras, em Belo Horizonte, MG, de 2002 a 2006. Comparou-se o número de homicídios ocorridos nessa localidade com os de outras favelas violentas e não violentas e outros bairros da cidade, em cada uma das fases do Programa. Para testar a hipótese de que a redução dos homicídios resultou das ações implementadas pelo Programa, foi elaborado um modelo estatístico baseado em modelos lineares generalizados. RESULTADOS: Nos primeiros seis meses obteve-se 69% de redução no número médio de homicídios. Nos períodos de refluxo e retomada parcial do Programa, o efeito de redução dos homicídios diminuiu, mas a diferença entre coeficientes com aquele do período inicial não foi estatisticamente significante. Mesmo com a retomada integral do Programa, o efeito continuou similar aos dos períodos anteriores, provavelmente porque o Programa foi implantado em outras favelas violentas da cidade. CONCLUSÕES: Os resultados apontam que o modelo do Programa Fica Vivo pode constituir uma importante alternativa para prevenção de homicídios contra jovens em comunidades que apresentem características semelhantes às da experiência piloto no Morro das Pedras.OBJETIVO: Evaluar el impacto del programa de prevención de homicidios.

Biomonitoring has been used as an alternative method to study the air pollution in several countries. The lichen, or lichenized fungi, is one of the most efficient on air pollution biomonitoring among the biomonitors. However, in Brazil, systematic use of lichens as biomonitors of environmental pollution is quite rare. In order to make an assessment of the air quality of the Mangabeiras' Park, this study was conducted by measuring the concentration of elements accumulated in the lichen thallus. This park, located in Belo Horizonte (Minas Gerais, Brazil), is the greatest green area in the city, and an apparent region of non polluted air. During the development of the study, epiphytic lichens of several species were collected using a steel stainless knife, taking samples of similar sizes from 1.5 m from the soil. The lichens selection was based on morphological similarities, such as color and type of the thallus. The elemental concentration determination was carried out applying the neutron activation technique, k 0 -standardization method, using the TRIGA Mark I IPR-R1 research reactor located at CDTN/CNEN. The lichen samples presented expressive concentrations of Ba, Fe, K, Na and Zn. However, the presence of other characteristic soil elements from the region, such as As, Th and U, suggests the influence of the mining activity area, located in the surroundings. (author)

Full Text Available Today, one of the main challenges faced in urban logistics is the distribution of goods. In Brazil, mid to large cities have experienced consequences of unplanned urban sprawl and lack of adequate transportation infrastructure. The relationship between urban planning and transport stands out the attractiveness of some urban activities with direct impacts on the movement of people and goods and other component elements of urban space. The segment of bars and restaurants falls within this context, therefore is a vital activity responsible for significant percentage of jobs and revenue in a city. Altogether, foods & beverages commercial activities move daily large volumes of goods to meet the need of customers. This paper presents the results of a freight trip generation model developed for pubs and restaurants in Belo Horizonte (Brazil. Once performed the model determined the number of trips generated per day per establishment. In order to expand the discrete result to a continuous one, the results were geographically interpolated to a continuous surface and extrapolated within the city limits. The data for the freight trip generation model were obtained by survey. For this, we designed a structured questionnaire to obtain information about goods, frequency, operational time, place of performance of the loading/unloading of goods, establishment size and the number of employees. Besides these information, we investigated the acceptance of alternative practices in the delivery of goods, such as off-peak delivery. To accomplish the proposed models, we applied a simple linear regression, correlating the following variables: (i Number of trips versus area of the establishment; (ii Number of trips versus number of employees; (iii Number of trips versus operation day of the establishment. With the results of the linear regression for travel generations, conducted the data interpolation based on the standard deviation of the results to define the sample

The twentieth century witnessed several diasporas. Some of them clearly addressed by the vehicles of mass communication, others less so. This study addresses the emergence of a movement of affirmation of black identity in Brazil, the movement Black-Rio, which appeared in the mid-70s. It suffered persecution, not only on the political side, but also from the media, until its extinction in the same decade. The importance of the Black-Rio was confirmed thirty years later, with the constitution of the Quarteirão do Soul in Belo Horizonte, a movement with similar ideology. It started downtown in 2004 with a group of friends, became a space of sociability and affirmation of black identity and, like its predecessor, begins to suffer harassment. Keywords: Black identity.

Entrance Surface Air Kerma (Ka,e) values for different radiographic procedures were internationally established and recommended aiming patient protection. In this work, we evaluated patient doses from chest X-ray examinations, postero-anterior (PA) and lateral (LAT) projections, in Belo Horizonte ECU, as well as the X-ray equipment performance. X-ray tube outputs were measured. Patient's biotype data and exposure radiographic factors were collected, allowing the Ka,e determination. For the dosimetric evaluation only the examinations parameters with its images approved according to the European Quality Criteria were considered. Data from 541 patients were collected from a total of 897 radiographic procedures, once not all patients were submitted also to the LAT incidence. For adult patients the third quartile of the Ka,e values were less than or equal to the radiodiagnostic reference levels recommended by Brazilian legislation in the 5 ECUs evaluated. For pediatric patients chest examinations in PA and LAT projections, Ka,e values for the age groups 1 to 5 and 5 to 10 years old were close to the values recommended by the European Community. However, for the age group 10 to 15 years, values were found above the reference level in both incidences. For chest LAT projection, Ka,e values were twice higher than the reference level. In general, although Ka,e distributions are below the radiodiagnostic reference levels recommended by the national and international agencies, there is still the possibility of optimization, through an effective quality assurance program and quality control. This work contributes for the proposal of regional reference levels, consistent with national reality. (author)

Full Text Available In this paper, a series of specific studies were carried out to investigate the complex form of fracture networks and figure out the multi-scale flowing laws of nano/micro pores–complex fracture networks–wellbore during the development of shale reservoirs by means of horizontal well fracturing. First, hydraulic fractures were induced by means of Brazilian splitting tests. Second, the forms of the hydraulic fractures inside the rock samples were observed by means of X-ray CT scanning to measure the opening of hydraulic fractures. Third, based on the multi-scale unified flowing model, morphological description of fractures and gas flowing mechanism in the matrix–complex fracture network–wellbore, the productivity equation of single-stage horizontal well fracturing which includes diffusion, slipping and desorption was established. And fourthly, a productivity prediction model of horizontal well multi-stage fracturing in the shale reservoir was established considering the interference between the multi-stage fracturing zones and the pressure drop in the horizontal wellbore. The following results were obtained. First, hydraulic fractures are in the form of a complex network. Second, the measured opening of hydraulic fractures is in the range of 4.25–453 μm, averaging 112 μm. Third, shale gas flowing in different shapes of fracture networks follows different nonlinear flowing laws. Forth, as the fracture density in the strongly stimulated zones rises and the distribution range of the hydraulic fractures in strongly/weakly stimulated zones enlarges, gas production increases gradually. As the interference occurs in the flowing zones of fracture networks between fractured sections, the increasing amplitude of gas production rates decreases. Fifth, when the length of a simulated horizontal well is 1500 m and the half length of a fracture network in the strongly stimulated zone is 100 m, the productivity effect of stage 10 fracturing is the

Project Horizonte, an open cohort of homosexual and bisexual HIV-1-negative men, is a component of the Minas Gerais AIDS Vaccine Program of the Federal University of Minas Gerais, Belo Horizonte, Brazil. Its objectives included the evaluation of seroincidence of HIV, to ascertain the role of counseling on behavior modification and to assess their willingness to participate in future HIV vaccine trials. Various means of recruitment were used, including pamphlets, notices in community newspapers, radio, and television, at anonymous testing centers, and by word of mouth. From October 1994 to May 1999, 470 volunteers were enrolled. Their mean age was 26 years and over 70% of them had high school or college education. During the follow-up, they were seen every 6 months, when they received counseling and condoms, and when HIV testing was done. Eighteen seroconversions were observed, and the incidence rates estimates were 1.75 per 100 and 1.99 per 100 person-years, for 36 and 48 months of follow-up, respectively. During the entire period, 139 volunteers were lost to follow-up. Among them, 59 (42.4%) never returned after the initial visit and 51 (36.7) came only once after their initial visit. No losses were observed for those observed during follow-up for more than 3 years. At enrollment, 50% of participants said they would participate in a vaccine trial, and 30% said they might participate. The results obtained up to this moment confirm the feasibility of following this type of cohort for an extended period, estimating HIV incidence rate, and evaluating counseling for safe sexual practices in preparation for clinical trials with candidate HIV vaccines in Brazil.

With a working gas capacity of 1,44 billion m{sup 3} (Vn) the natural gas storage facility at Bierwang is one of the largest storage facilities of E.ON Gas Storage (in Germany) and also one of the largest porous rock storages in Germany. The natural gas is stored in the tertiary storage horizons of the Chattian Hauptsand and Nebensand. To increase the storage capacity a second development well was planned for the Chattian Nebensand II (approx. 1680 m below ground). Following a comprehensive technical investigation the BW 502 well was planned as a horizontal well intended to provide a 300 m exposed section length through the reservoir. In a first step a pilot well was drilled to examine the Nebensand II which had been explored only to a limited extent before; the pilot well was also to provide accurate data on depth, thickness and dip. The results obtained indicated that the Nebensand II was only 4 m thick instead of 6 m as originally assumed. An azimuthal LWD resistivity tool was therefore used for reservoir navigation to allow horizontal drilling despite the lower thickness found. The technology allowed drilling of the horizontal well over its entire length of 315 m within a max. 1.5 m corridor relative to the reservoir top. Drilling confirmed that the actual formation found corresponded to the reservoir formation plan. Drilling operations were completed successfully. The well has been commissioned in the spring of 2010.

The natural radioactivity is responsible for approximately 80% of the average annual radiation dose received by human being. This work aims at the knowledge of the origin and distribution from the natural radioactivity and the potential risk due to radon in Belo Horizonte. This study was based on local geology, composed mainly by granitic and gneissic rocks and in a previously study of indoor air radon concentration, that pointed out dwellings with high concentrations, above some international action levels. It presents the mapping of the spatial distribution of uranium, thorium, potassium, dose rate and of the total gamma count rate, distributed throughout the central region of the city that is within the boundaries of Contorno Avenue. The work was developed with a survey made inside a car with a portable gamma detector, RS-230, Radiation Solutions, coupled to a Global Positioning System (GPS) in every street within the Contorno Avenue and after using geoprocessing techniques and statistics, the results was spatially distributed and classified according to the background in five classes (very low, low, medium, high and very high). It was observed next to the Liberdade Square, were found total gamma count rate 'very high'. After performing a more detailed analysis on the radiation background it was observed that this high level of radiation in specific locations appear to originated from the cobblestones of the streets, granitic rocks,which came from quarries in the region around the Contorno Avenue and that do not correspond to gamma radiation emanating from the local soil.

The natural radioactivity is responsible for approximately 80% of the average annual radiation dose received by human being. This work aims at the knowledge of the origin and distribution from the natural radioactivity and the potential risk due to radon in Belo Horizonte. This study was based on local geology, composed mainly by granitic and gneissic rocks and in a previously study of indoor air radon concentration, that pointed out dwellings with high concentrations, above some international action levels. It presents the mapping of the spatial distribution of uranium, thorium, potassium, dose rate and of the total gamma count rate, distributed throughout the central region of the city that is within the boundaries of Contorno Avenue. The work was developed with a survey made inside a car with a portable gamma detector, RS-230, Radiation Solutions, coupled to a Global Positioning System (GPS) in every street within the Contorno Avenue and after using geoprocessing techniques and statistics, the results was spatially distributed and classified according to the background in five classes (very low, low, medium, high and very high). It was observed next to the Liberdade Square, were found total gamma count rate 'very high'. After performing a more detailed analysis on the radiation background it was observed that this high level of radiation in specific locations appear to originated from the cobblestones of the streets, granitic rocks,which came from quarries in the region around the Contorno Avenue and that do not correspond to gamma radiation emanating from the local soil.

Ocorreu em duas etapas: na primeira, foram analisadas 2.906 das 168.237 notificações de receitas aviadas por estabelecimentos farmacêuticos da cidade, em 2003. Observou-se uma baixa qualidade nas notificações. O consumo projetado foi de 19,75 DDD/mil habitantes/dia. A substância mais consumida foi o fenproporex (59,8%. Uma farmácia foi responsável por 39,8% das dispensações. Na segunda etapa, foram analisados 14.554 registros do livro de receituário geral da farmácia que mais dispensou tais produtos, no período de abril a agosto de 2005. Os anorexígenos responderam por 9,2% das manipulações e 91,8% deles foram prescritos para uso concomitante com outra substância: 43% com clordiazepóxido, 50,6% com fluoxetina, 7,5% com outro anorexígeno e 28,2% com bromazepam. Os resultados observados sugerem um uso indiscriminado e irracional de anorexígenos neste município, sendo fundamental aprimorar a regulação do mercado de produtos manipulados. Para tanto, é necessário uma melhor compreensão do papel da farmácia nessa regulação e o papel dos prescritores no uso racional dessas substâncias.This retrospective study in Belo Horizonte, Minas Gerais, Brazil, aimed to provide indicators on the sale and consumption of anorexigenic substances.

Six hundred and one 8- and 9-year-old children were randomly selected from schools in Belo Horizonte, MG, Brazil. After formal authorization was obtained from their parents, the children were interviewed and clinically examined by a single examiner. The Chi squared test was applied and the odds ratio obtained. The prevalence of toothache was 45.9% (276/601, of which 15.6% (94/601 had occurred during the previous month. Among the children who had experienced pain, 39.4% (109/276 classified its severity as intense or very intense. Nearly 35% (96/276 were awoken by the pain, and 63.8% (176/276 were unable to carry out daily tasks as a result. The prevalence of pain was greater among children from less privileged economic groups, in which the mothers' level of schooling was lower (0-7 years of formal study and who showed poorer conditions of oral health, determined by the presence of dental and periodontal pathology (p<0.05. Gender did not influence either the experience of toothache or its severity and impact. The prevalence of toothache found in the age group between 8 and 9 years is very high and associated to social determinants and poorer conditions of oral health.

Full Text Available INTRODUTION: A major concern with the visceral leishmaniasis (VL is its high lethality rate, even with proper treatment. Low age, prior malnutrition, disease duration prior to diagnosis, severe anemia, fever for more than 60 days, diarrhea and jaundice are known poor prognostic factors. The goals of this study are to describe the clinical and laboratory characteristics of VL among children under 12 years of age and to identify the factors associated with VL poor outcome. METHODS: Two hundred and fifty children under 12 years of age with confirmed VL admitted to Hospital João Paulo II (FHEMIG, Belo Horizonte, Brazil, between January 2001 and December 2005 were evaluated retrospectively. The primary outcome was the poor clinical evolution: sepsis, and/or pneumonia, and/or urinary tract infection, and/or of bleeding (expect epistaxis, and/or severe neutropenia (neutrophil < 500 cells/mm3. Odds ratio (crude and adjusted and its 95% confidence interval for each variable were calculated. Values less than 0.05 were considered significant. RESULTS: Average age was 3.3 years (3.6 months-11.6 years, 71.2% were younger than 5 years and 47.2% lived in Metropolitan Area of Belo Horizonte. The mean fatality rate was 3.6%. Sixty-six (26.4% patients presented poor evolution. After a multivariate analysis, age <18 months, abnormal respiratory physical examination on hospital admission, and platelets <85,000/mm3 remained associated with increased chance of poor evolution. CONCLUSIONS: The results suggest that patients aged between 12 and 18 months, with platelet counts bellow 85,000/mm3, and respiratory abnormalities at admission should be considered potentially severe.

In the present study, we investigated the spatial change of sediment nitrite-dependent anaerobic methane-oxidizing (n-damo) organisms in the mesotrophic freshwater Gaozhou Reservoir (6 different sampling locations and 2 sediment depths (0-5 cm, 5-10 cm)), one of the largest drinking water reservoirs in China. The abundance of sediment n-damo bacteria was quantified using quantitative polymerase chain reaction assay, while the richness, diversity, and composition of n-damo pmoA gene sequences were characterized using clone library analysis. Vertical and horizontal changes in sediment n-damo bacterial abundance occurred in Gaozhou Reservoir, with 1.37 × 10 5 to 8.24 × 10 5 n-damo 16S rRNA gene copies per gram of dry sediment. Considerable horizontal and vertical variations of n-damo pmoA gene diversity (Shannon index = 0.32-2.50) and composition also occurred in this reservoir. Various types of sediment n-damo pmoA genes existed in Gaozhou Reservoir. A small proportion of n-damo pmoA gene sequences (19.1%) were related to those recovered from "Candidatus Methylomirabilis oxyfera". Our results suggested that sediment n-damo pmoA gene diversity might be regulated by nitrite, while n-damo pmoA gene richness might be governed by multiple environmental factors, including total organic carbon, total phosphorus, nitrite, and total nitrogen.

Full Text Available In order to characterize the epidemiology of American Cutaneous Leishmaniasis (ACL in a periurban area of the municipality of Sabará in the metropolitan region of Belo Horizonte (MRBH, an area until then considered free of the disease, a cross sectional survey was undertaken in 1990. The survey of the population consisted of 1119 interviews and 881 clinical examinations using Montenegro's skin test (MST. A low prevalence (3.7% of positive MST was encountered. The disease had been occuring in the area for about 20 years in the form of sporadic cases. The predominant species of sandfly both in domestic areas and nearby areas of secondary vegetation was Lutzomyia whitmani. A canine survey of delayed hypersensitivity to the antigen P10,000 identified only one dog with a positive reaction out of 113 examined. The transmission of ACL in MRBH was confirmed. The occurrence of the disease in women, children and individuals with no contact with forest areas as well as the presence of potential vector species in the domiciliar environment, suggests the transmission of the disease in this environment.

This paper discusses the challenges involved in adopting an integrated approach to urban water policies and management, a particularly problematic issue in Brazil due to the incomplete nature of urbanization, defined as the lack of adequate and/or universalized access to infrastructure and services, informal housing and conflicts between environmental protection and social housing needs. In the last two decades strong social movements have influenced urban environmental policies from national to local levels. In Belo Horizonte since 1993, decision-making processes have involved important mechanisms of democratic inclusion, which have contributed to fairer urban policies. A brief discussion of the concept of governance follows, introducing the municipal urban policy within which drainage and sanitation policies have been implemented. This paper presents the constitutional and institutional role of the five municipal committees dealing with water governance issues, as they are important arenas for civil society participation. The main constraints to achieving integrated urban water governance at the local level and the extent to which such policies are able to reduce social inequalities and promote social environmental justice in the use and appropriation of urban water, are discussed. This paper is part of the SWITCH-Sustainable Water Management Improves Tomorrow's Cities' Health-research network.

Full Text Available The prevalence, virological and epidemilogical aspects of the hepatitis C virus (HCV and the hepatitis B virus (HBV infections vary among hemodialysis patients in different countries. Aiming at analyzing these aspects of HCV and HBV infections in hemodialysis patients in Belo Horizonte, MG, Brazil, we studied three hemodialysis units including 434 patients. Serology was used to detect anti-HCV and HBsAg. Reverse trancriptase nested polymerase chain reaction (RT-nested-PCR of the 5'-noncoding region was used to detect circulating HCV RNA and restriction fragment length polymorphism analysis for genotyping. Seroprevalence varied from 26.5% to 11.1% for hepatitis C and from 5.9% to 0% for hepatitis B. Risk factors observed for HBV and/or HCV infections were the number of patients per dialysis unit, duration of treatment, number of clinics attended, number of blood units transfused, and lower level scholarity. Alanine aminotransferase levels were altered with a higher frequency in HBV or HCV seropositive patients. Half of ten patients, negative for anti-HCV, had detectable viremia by RT-nested-PCR, indicating that this technique should be used to confirm infections in this group of patients. The HCV genotype 1 was the most frequently observed, followed by the genotype 2, but no correlation was detected between genotype and clinical or epidemiological data.

Mariana Martins Godin

Full Text Available ABSTRACT BACKGROUND: The term dangerous universal blood donor refers to potential agglutination of the erythrocytes of non-O recipients due to plasma of an O blood group donor, which contains high titers of anti-A and/or anti-B hemagglutinins. Thus, prior titration of anti-A and anti-B hemagglutinins is recommended to prevent transfusion reactions. OBJECTIVE: The aim of this study was to estimate the frequency of dangerous universal donors in the blood bank of Belo Horizonte (Fundação Central de Imuno-Hematologia - Fundação Hemominas - Minas Gerais by determining the titers of anti-A and anti-B hemagglutinins in O blood group donors. METHOD: A total of 400 O blood group donors were randomly selected, from March 2014 to January 2015. The titers of anti-A and anti-B hemagglutinins (IgM and IgG classes were obtained using the tube titration technique. Dangerous donors were those whose titers of anti-A or anti-B IgM were ≥128 and/or the titers of anti-A or anti-B IgG were ≥256. Donors were characterized according to gender, age and ethnicity. The hemagglutinins were characterized by specificity (anti-A and anti-B and antibody class (IgG and IgM. RESULTS: Almost one-third (30.5% of the O blood group donors were universal dangerous. The frequency among women was higher than that of men (p-value = 0.019; odds ratio: 1.66; 95% confidence interval: 1.08-2.56 and among young donors (18-29 years old it was higher than for donors between 49 and 59 years old (p-value = 0.015; odds ratio: 3.05; 95% confidence interval: 1.22-7.69. There was no significant association between dangerous universal donors and ethnicity, agglutinin specificity or antibody class. CONCLUSION: Especially platelet concentrates obtained by apheresis (that contain a substantial volume of plasma, coming from dangerous universal donors should be transfused in isogroup recipients whenever possible in order to prevent the occurrence of transfusion reactions.

Full Text Available ABSTRACT Visceral leishmaniasis (VL has spread rapidly across cities in the metropolitan region of Belo Horizonte. The aim of this study was to investigate VL dynamics in a prospective cohort study of dogs in Juatuba, between 2010 and 2011, to confirm the incidence of Leishmania infantum, and to assess possible risk factors associated with infection. An observational and prospective closed cohort study was performed using serology testing in dogs, randomly selected from the whole municipality. All seronegative dogs, or dogs with inconclusive results were monitored using indirect immunofluorescence (IIF at 6-month intervals. The dog's owners completed a semi-structured questionnaire to assess possible causal factors of seroconversion, and the responses were assessed using logistic regression. The canine incidence coefficient was 206/1,000 dogs per year (CI: 178-238, and a cluster was identified in an area with a high concentration of seropositive dogs, but a low overall canine population. Large dogs were identified as a risk factor and the following variables were identified as protection factors: dogs aged over 4 years, daily peridomicile cleaning, and better socioeconomic conditions. VL is spreading over a large area in Juatuba in a short period of time.

Infection with the hepatitis B and C viruses may occur through contact with infected body fluids, including injury with infected sharps. Collectors of domestic or healthcare wastes are potentially exposed to these infections. The aim of this article is to investigate the risk factors associated with the prevalence of hepatitis B and C viruses (HBV and HCV) infection among domestic and healthcare waste workers in Belo Horizonte, Brazil. A cross-sectional study of hepatitis B and C infection was conducted from November 2014 to January 2015, through blood sample collection and interviews about socio-demographic factors with 61 workers exposed to healthcare waste ('exposed') and 461 exposed only to domestic wastes ('unexposed'). The prevalence of antibodies to HCV (Anti-HCV) antibodies was 3.3% in 'exposed' workers and 0.9% in 'unexposed', and of antibody to hepatitis B core antigen (Anti-HBc) was 9.8% and 5.6% in 'exposed' and 'unexposed' workers, respectively. Only 207 (44.9%) of those exposed to domestic waste and 45 (73.8%) of those handling healthcare waste were effectively immunised against hepatitis B virus (HBV). Exposures to domestic waste and to healthcare wastes were associated with similar risks of infection with HBV. The risk of hepatitis C virus (HCV) infection was marginally higher among healthcare waste workers compared with domestic waste workers, probably because of needlestick accidents owing to deficient sharps management systems. Immunisation against hepatitis B and screening tests to ensure the success of vaccination should be a condition for recruitment for both groups of waste workers. © The Author(s) 2016.

Reservoir development for unconventional resources such as tight gas reservoirs is in increasing demand due to the rapid decline of production in conventional reserves. Compared with conventional reservoirs, fluid flow in water-bearing tight gas reservoirs is subject to more nonlinear multiphase flow and gas slippage in nano/micro matrix pores because of the strong collisions between rock and gas molecules. Economic gas production from tight gas reservoirs depends on extensive application of water-based hydraulic fracturing of horizontal wells, associated with non-Darcy flow at a high flow rate, geomechanical stress sensitivity of un-propped natural fractures, complex flow geometry and multiscale heterogeneity. How to efficiently and accurately predict the production performance of a multistage fractured horizontal well (MFHW) is challenging. In this paper, a novel multicontinuum, multimechanism, two-phase simulator is established based on unstructured meshes and the control volume finite element method to analyze the production performance of MFHWs. The multiple interacting continua model and discrete fracture model are coupled to integrate the unstimulated fractured reservoir, induced fracture networks (stimulated reservoir volumes, SRVs) and irregular discrete hydraulic fractures. Several simulations and sensitivity analyses are performed with the developed simulator for determining the key factors affecting the production performance of MFHWs. Two widely applied fracturing models, classic hydraulic fracturing which generates long double-wing fractures and the volumetric fracturing aimed at creating large SRVs, are compared to identify which of them can make better use of tight gas reserves.

Full Text Available The Metropolitan Area of Belo Horizonte is consisted of 34 municipalities, however approximately 79,68% of its population is concentrated at the conurbation zone with 19 municipalities. This zone presented different expansion axis (North, South, West throughout the time. This article intends to assess the investments made in basic sanitation infrastructure (access to water supply, sewage collection network and garbage collection service within the period from the years 2000 to 2010. For this purpose, land cover maps for these years were created to identify the new urban expansion axis. Maps of the census sectors of both years were also made with the percentage of households attended by the basic sanitation services infrastructure, as well as the population density and average income of the householder. Considering the results, we have observed that the investments in basic sanitation infrastructure in the last ten years were not sufficient, given the fact that the region with the largest population of Minas Gerais still has precarious conditions regarding the access to water supply and sewage networks. The least of the problems, but still a problem, is the garbage collection services, given the fact that to collect, the investment is low but it is important to highlight that the data do not bring information about the treatment and disposal of the garbage or sewage, they only inform us were those types of residue are collected.

The Performance of Surfactant-Polymer Flooding in Horizontal Wells Consisting of Multilayers in a Reservoir System

2016-03-01

Full Text Available Surfactant-polymer (SP flooding has been demonstrated to be an effective method to recover oil in the enhanced oil recovery (EOR stage when water flooding is no longer relevant. Theoretically, adding surfactant causes the reduction of the interfacial tension between oil and water in pores, therefore reducing the residual oil saturation, whereas the sweep efficiency will be significantly improved by the polymer injection as a result of proper mobility control. With regard to the well patterns, water flooding has demonstrated a high productivity in horizontal wells. Recently, other EOR processes have been increasingly applied to the horizontal wells in various well patterns. In this study, the efficiency of SP flooding applied to horizontal wells in various well configurations is investigated in order to select the best EOR performance in terms of either a technical or economical point of view. Furthermore, the reservoir is assumed to be anisotropic with four different layers that have same porosity but different permeability between each layer. The study figures out that, the utilization of a horizontal injector and producer always gives a higher oil production in comparison with the reference case of a conventional vertical injector and producer; however, the best EOR performances that demonstrate the higher oil recovery and lower fluid injected volume than those of the reference case are achieved when the production well is located in bottom layers and parallel with the injection well at a distance. While the location of producer decides oil productivity, the location of injector yet affects the uniformity of fluids propagation in the reservoir. A predefined feasibility factor is also taken into consideration in order to reject the infeasible cases that might give a high oil production but require a higher injected volume than the reference case. This factor is used as an economic parameter to evaluate the success of the EOR performance. The

According to the Vaccine Coverage Survey, performed in 2007, the immunization coverage against hepatitis B in Belo Horizonte, for infants under one year old, was below the level proposed by the Brazilian National Program of Immunization. This vaccine was used as basis for evaluating the involvement of health professionals in the process of vaccination in two Basic Health Units (UBS, acronym in Portuguese) in the city. This study is qualitative and uses the notions of Social Representations Theory and the method of Structural Analysis of Narrative to carry out the interviews and data analysis. The results show flaws related to controlling and use of the mirror card and the parent orientation, and also the monitoring of vaccination coverage (VC) and use of VC data as input for planning health actions. It was observed that the working process in the UBS is focused on routine tasks, with low creativity of the professionals, which includes representations that maintain strong tendency to value activities focused on the health of individuals to the detriment of public health actions. In conclusion, the vaccination process fault can be overcome with a greater appreciation of everyday actions and with a much better use of local information about vaccination, and some necessary adjustments within the UBS to improve public health actions.

To investigate the association between functional health literacy and sociodemographic factors, quality of life, self-perception of health, and perception of contexts of violence in adolescents in state schools in Belo Horizonte. This is a cross-sectional analytical observational study with a probabilistic sample of 384 adolescents between 15 and 19 years old. Data collection was carried out in schools and included self-reporting questionnaires to assess the functional health literacy, socioeconomic classification, self-perceived health, and quality of life. The reliability of internal consistency of the functional health literacy instrument was determined by calculating Cronbach's alpha coefficient. A multivariate logistic regression analysis was performed using hierarchical data entry according to the level of determination of the theoretical model established. In order to evaluate the association, a significance level of 5% was considered, while the Odds Ratio used as a measure of the magnitude of the associations. The functional health literacy instrument presented a coefficient of 0.766, indicating adequate internal consistency. More than half of teenagers presented good functional health literacy. In the final model of multivariate analysis, the variables not practicing a religion (p = 0.006; OR = 2.108); social domain of quality of life (p = 0.004; OR = 1.022); and educational domain of quality of life (p = 0.009; OR = 1.019) remained associated with functional health literacy. Not practicing a religion and the increase in the scores of social and educational domains of quality of life increased the chances of better functional health literacy.

Full Text Available ABSTRACT The Montreal Battery of Evaluation of Amusia (MBEA is a battery of tests that assesses six music processing components: scale, contour, interval, rhythm, metric, and music memory. The present study sought to verify the psychometric characteristics of the MBEA in a sample of 150 adolescents aged 14-18 years in the city of Belo Horizonte, Minas Gerais, Brazil, and to develop specific norms for this population. We used statistical procedures that explored the dimensional structure of the MBEA and its items, evaluating their adequacy from empirical data, verifying their reliability, and providing evidence of validity. The results for the difficult levels for each test indicated a trend toward higher scores, corroborating previous studies. From the analysis of the criterion groups, almost all of the items were considered discriminatory. The global score of the MBEA was shown to be valid and reliable (r K-R20=0.896 for assessing the musical ability of normal teenagers. Based on the analysis of the items, we proposed a short version of the MBEA. Further studies with larger samples and amusic individuals are necessary to provide evidence of the validity of the MBEA in the Brazilian milieu. The present study brings to the Brazilian context a tool for diagnosing deficits in musical skills and will serve as a basis for comparisons with single case studies and studies of populations with specific neuropsychological syndromes.

In Brazil, nonprofit or charitable organizations are the oldest and most traditional and institutionalized form of relationship between the third sector and the state. Despite the historical importance of charitable hospital care, little research has been done on the participation of the nonprofit sector in basic health care in the country. This article identifies and describes non-hospital nonprofit facilities providing systematically organized basic health care in Belo Horizonte, Minas Gerais, Brazil, in 2004. The research focused on the facilities registered with the National Council on Social Work, using computer-assisted telephone and semi-structured interviews. Identification and description of these organizations showed that the charitable segment of the third sector conducts organized and systematic basic health care services but is not recognized by the Unified National Health System as a potential partner, even though it receives referrals from basic government services. The study showed spatial and temporal overlapping of government and third-sector services in the same target population.

Full Text Available Abstract Obesity prevalence is rapidly increasing in developing countries. Existing research investigating social patterning of obesity and its risk factors in Latin American urban contexts has inconsistent findings. This study analyzed a multistage household survey in adults in Belo Horizonte, Minas Gerais State, Brazil. Marginal models were used to examine the association of education and household and neighborhood income with body mass index (BMI, obesity, physical inactivity, and low fruit and vegetable intake after adjusting for age and ethnicity and stratifying by sex. BMI and obesity were inversely associated with education in women. BMI was positively associated with household and neighborhood income in men. Additionally, physical inactivity and low fruit and vegetable intake were inversely associated with education and household income in both men and women, and physical inactivity was inversely associated with neighborhood income in men. Understanding the drivers of these patterns will allow for development of appropriate policy and interventions to reduce cardiovascular disease risk in large cities in Latin America.

Procurou-se compreender a vivência da condição juvenil pelos participantes do programa a partir de suas experiências de escolarização e trabalho e de seus projetos de futuro, para assim compreender os significados e sentidos do programa para eles. Na primeira etapa da pesquisa, foram aplicados 103 questionários a fim de construir um breve perfil socioeconômico dos alunos. Após o levantamento inicial dos dados, duas turmas foram selecionadas e observadas. Posteriormente, foram selecionados dez jovens para a realização de entrevistas semiestruturadas. A pesquisa revelou uma maioria de mulheres, negros e jovens em condições precárias de trabalho ou desempregados e com uma sociabilidade restrita em relação a outros estratos da população. Evidenciou-se que as desigualdades sociais têm uma importância central nas trajetórias de vida desses jovens, com impactos marcantes em suas experiências atuais e em suas expectativas em relação ao futuro. Com base nesse solo comum, foi possível perceber uma diversidade de experiências a partir das quais são produzidos diferentes significados e motivações em relação à escolarização, o que delimitava também a relação construída com o programa. De uma maneira geral, a busca pela certificação escolar era o principal interesse dos participantes.This paper discusses some of the outcomes of a qualitative research carried out between 2009 and 2011 which investigated the trajectories of young participants in the Program ProJovem Urbano (National Program for Youth Inclusion in 2009, in the city of Belo Horizonte, state of Minas Gerais, in Brazil.

Full Text Available A geodiversidade, cujo significado do termo é análogo à biodiversidade, designa a diversidade natural da componente abiótica da natureza, composta pelos seguintes elementos: solo, rochas, formas de relevo, dentre outros. Apesar de recentes, os estudos em geodiversidade já apresentam uma discussão teórica bastante significativa. Contudo, a aplicação de métodos quantitativos, geralmente desenvolvidos com uso de Sistemas de Informação Geográficas (SIG ainda é incipiente, especialmente no Brasil. A Área de Proteção Ambiental Sul da Região Metropolitana de Belo Horizonte (APA Sul da RMBH, localizada no Quadrilátero Ferrífero (QF - Minas Gerais, possui um rico patrimônio natural, principalmente no que se refere aos elementos geológicos. Sua geodiversidade inclui afloramentos, solos, cachoeiras e diversas feições de relevo. Além disso, a área em questão apresenta grande importância para a Região Metropolitana de Belo Horizonte (RMBH, uma vez que nela estão localizados os principais mananciais de água potável para abastecimento da população. Deste modo, o principal objetivo deste trabalho é apresentar os procedimentos adotados para o cálculo e geração do mapa de geodiversidade à partir da utilização de um Sistema de Informação Geográfica, para a região da APA Sul da RMBH. Como resultado foi obtido o mapa de geodiversidade bem como a quantificação relativa das áreas de muito alta, alta, média e baixa diversidade abiótica que podem ser propostas futuramente como área prioritárias para a conservação.  O uso do SIG viabilizou o cálculo do índice de geodiversidade da APA Sul bem como a sua representação cartográfica.

Full Text Available Neste trabalho, investiga-se como desigualdades de classe e de gênero atuam no sentido de reduzir o grau de autonomia de adolescentes (15 a 19 anos e mulheres jovens (20 a 24 anos, influenciando seu comportamento sexual e reprodutivo, especificamente na experiência da gravidez na adolescência. Na análise foram utilizados dados provenientes de dois inquéritos, cuja amostra total foi de 648 jovens do sexo feminino entre 15 e 24 anos de idade, 292 residentes em bairros de classe média e 356 em favelas situados na região centro-sul da cidade de Belo Horizonte, Brasil. Nos resultados, encontrou-se uma prevalência bruta de 27,3% de gravidez até os 19 anos entre as jovens residentes em favelas e de 1,7% entre as moradoras em bairros da região centro-sul de Belo Horizonte. Os dados apontam para uma relação direta entre a gravidez na adolescência com o controle e a violência por parte do parceiro. Entre aquelas residentes em favelas, 48% das que declararam ter sofrido violência física por parte de um parceiro e 58% das que declararam ter sofrido violência sexual haviam engravidado ao menos uma vez antes dos 19 anos. A associação da violência de gênero com a gravidez na adolescência se manteve presente mesmo quando controlada por classe social, ainda que seu peso fosse muito mais pronunciado entre as jovens de baixa renda. Esses resultados reforçam a importância de se aprofundar a compreensão acerca do impacto das desigualdades de classe e gênero no comportamento sexual e reprodutivo de adolescentes e mulheres jovens.

La hipótesis es que un gobierno municipal comprometido con la equidad puede reducir desigualdades, apoyándose en el Sistema Único de Salud. Trabajamos con el Índice de Calidad de Vida Urbana (IQVU, usado en el municipio para reconocer las desigualdades en las condiciones de vida y el diferencial de los coeficientes de mortalidad infantil (CMI, neonatal e pos-neonatal en los nueve distritos sanitarios. Otras acciones fueron medidas por la ejecución de obras municipales, por medio del Presupuesto Participativo y la Programación Abierta. El IQVU se mostró apropiado para orientar la acción del gestor municipal. El CMI se mostró un buen indicador para medir la desigualdad en salud. Hubo reducción del CMI y de las brechas de mortalidad en los distritos estudiados. Verificamos mayor inversión de recursos físicos y financieros en los distritos de IQVU más bajo, pudiéndose afirmar que en el estudiado, el gobierno municipal redujo desigualdades.

Full Text Available OBJETIVOS: avaliar os aspectos clínicos, radiológicos, anátomo-patológicos e terapêuticos de uma série de casos de carcinoma ductal in situ (CDIS da mama de pacientes atendidos em três hospitais públicos de Belo Horizonte (MG. MÉTODOS: foram selecionados dos arquivos médicos todos os casos de câncer de mama diagnosticados entre os anos de 1985 e 2000, encontrando-se 179 casos com diagnóstico de CDIS. Fez-se revisão anátomo-patológica das lâminas e obtiveram-se dados clínicos completos, mamografias e informações sobre tratamento em 85 casos. RESULTADOS: a maioria dos casos eram assintomáticos e os diagnósticos foram feitos pela mamografia (68,2%, sendo as microcalcificações a alteração radiológica mais freqüente. Houve aumento progressivo no diagnóstico de CDIS ao longo dos anos simultâneo à introdução do exame periódico mamográfico. Houve concordância entre o diagnóstico inicial e após a revisão histopatológica em 72,9% dos casos. Em três casos, o diagnóstico original de CDIS não foi confirmado pela revisão, tratando-se de hiperplasias com atipias. O achado de microcalcificações radiológicas foi confirmado no estudo histopatológico em 95,6%. A metade dos pacientes foi submetida à mastectomia. Nos casos submetidos à linfadenectomia axilar, todos os linfonodos dissecados foram negativos para metástases. CONCLUSÕES: os dados encontrados estão de acordo com a literatura, que mostra um aumento do diagnóstico do CDIS a partir de 1990. Houve importante variação interobservador entre os diagnósticos anátomo-patológicos iniciais e os da revisão, sendo que os diagnósticos iniciais tendiam para malignidade. Houve grande número de tratamentos mais radicais como a mastectomia e esvaziamentos axilares, que provavelmente, com os conhecimentos atuais, seriam substituídos por tratamentos conservadores e biópsia do linfonodo sentinela.PURPOSE: to evaluate the clinical, radiological therapeutic and

Intense mining activities in Minas Gerais State, Brazil. Iron Quadrangle, the central region of Minas Gerais State- Brazil, has important mineral reserves of Fe (the World's second largest iron ore producer), Mn, Cu, Sb, As, Au, Al, and U. The intense mining activities in Minas Gerais State throw out tons of waste in the open air, water, sediment and soil. The considerable accumulated concentrations of heavy metals and toxic elements penetrate the soil, underground waters, rivers, and lakes jeopardizing the environment quality. A great amount of heavy metals enter Pampulha Reservoir via it's main tributaries (Sarandi and Ressaca). Although no water quality classification has been carried out for these tributaries, the reservoir is expected to be in class 2 of the CONAMA-86 system. The Pampulha Lake is a depth of 8 m and an area of 43 km 2 , in a hot, humid climate with a summer rainy season, >18 degree C in the coldest months. A great number of persons use the water for fishing and swimming in the contaminated water. The figure l localizes the Pampulha Lake in Brazil. Instrumental Neutron Activation Analysis, INAA, and Inductively Coupled Plasma-Mass Spectrometry-High Resolution, ICP-MSHR, were applied to determine Al, As, B, Ba, Co, Cr, Cs, Cu, Fe, K, Mg, Mn, Mo, Na, P, Pb, Rb, Zn and Ti.

The no-type curve with negative skin of a horizontal well has been found in the current research. Negative skin is very significant to transient well test and rate decline analysis. This paper first presents the negative skin problem where the type curves with negative skin of a horizontal well are oscillatory. In order to solve the problem, we propose a new model of transient well test and rate decline analysis for a horizontal well in a multiple-zone composite reservoir. A new dimensionless definition of r D is introduced in the dimensionless mathematical modelling under different boundaries. The model is solved using the Laplace transform and separation of variables techniques. In Laplace space, the solutions for both constant rate production and constant wellbore pressure production are expressed in a unified formula. We provide graphs and thorough analysis of the new standard type curves for both well test and rate decline analysis; the characteristics of type curves are the reflections of horizontal well production in a multiple-zone reservoir. An important contribution of our paper is that our model removed the oscillation in type curves and thus solved the negative skin problem. We also show that the characteristics of type curves depend heavily on the properties of different zones, skin factor, well length, formation thickness, etc. Our research can be applied to a real case study

The medical procedures of diagnosis and treatment that use radiopharmaceuticals generate radioactive wastes that can, after reaching the release limit, follow the conventional ways of collection and disposal of the urban solid wastes. This research aims to detect radiometrically the presence of radioactive wastes in the health-care wastes at the final disposal. It is pointed out that the legal limit for the release of solid wastes established by Brazilian National Commission of Nuclear Energy (CNEN) is 7,5x10 4 Bq/kg (2 μCi/kg). Measurements in the material of the garbage trucks that make the special collect from Health Service installations are performed, at Belo Horizonte sanitary landfill, using a NaI scintillation counter. Values above the established limit were found in 60% of the cases. The spectral analysis of 6 samples showed the presence of 99m Tc in 5 of them and 131 I in one. These radionuclides are the most common radionuclides used in Nuclear Medicine. In conclusion there are radioactive wastes released together with the health service wastes, due to the disregard of the decay time until the legal limit is achieved. (author)

Samples of soil, iron ore, and airborne particulate matter (size airborne particulate matter in the metropolitan area of Belo Horizonte, Minas Gerais, Brazil, are either from natural origin, as, for instance, re-suspension of particles from soil, or due to anthropogenic activities, meaning that it would be originated from the many iron ore minings surrounding the metropolitan area. Numerical simulations were used to model the atmospheric dispersion of the airborne particulate matter emitted by iron mining located at the Iron Quadrangle geodomain, Minas Gerais. Results from these numerical simulations supported identifying the sites with the highest concentrations of airborne particulate matter in the metropolitan area. Samples of these suspended materials were collected at the selected sites by using high-volume air samplers. The physicochemical features of the solid materials were assessed by X-ray fluorescence, X-ray diffraction, magnetometry, and 57 Fe Mössbauer spectroscopy. The soil materials were found to be rich in quartz, aluminum, organic matter, and low contents of iron, mainly as low crystalline iron oxides. The samples of the iron ores, on the other hand, contain high concentration of iron, dominantly as relatively pure and crystalline hematite (α-Fe 2 O 3 ). The samples of the airborne particulate matter are rich in iron, mainly as hematite, but contained also quartz, aluminum, and calcium. Mössbauer spectroscopy was used to evaluate the hyperfine structure of 57 Fe of the hematite both from the iron ore and the soil samples. The structural characteristics of the hematite of these particulate materials were further explored. The direct influence of the iron ore mining on the composition of the airborne particulate matter was clearly evidenced based on the trace ability of hematite to its source of emission. Even the atmospheric air on regions relatively far away from the mining activities is also significantly influenced.

Development of unconventional shale gas reservoirs (SGRs) has been boosted by the advancements in two key technologies: horizontal drilling and multi-stage hydraulic fracturing. A large number of multi-stage fractured horizontal wells (MsFHW) have been drilled to enhance reservoir production performance. Gas flow in SGRs is a multi-mechanism process, including: desorption, diffusion, and non-Darcy flow. The productivity of the SGRs with MsFHW is influenced by both reservoir conditions and hydraulic fracture properties. However, rare simulation work has been conducted for multi-stage hydraulic fractured SGRs. Most of them use well testing methods, which have too many unrealistic simplifications and assumptions. Also, no systematical work has been conducted considering all reasonable transport mechanisms. And there are very few works on sensitivity studies of uncertain parameters using real parameter ranges. Hence, a detailed and systematic study of reservoir simulation with MsFHW is still necessary. In this paper, a dual porosity model was constructed to estimate the effect of parameters on shale gas production with MsFHW. The simulation model was verified with the available field data from the Barnett Shale. The following mechanisms have been considered in this model: viscous flow, slip flow, Knudsen diffusion, and gas desorption. Langmuir isotherm was used to simulate the gas desorption process. Sensitivity analysis on SGRs’ production performance with MsFHW has been conducted. Parameters influencing shale gas production were classified into two categories: reservoir parameters including matrix permeability, matrix porosity; and hydraulic fracture parameters including hydraulic fracture spacing, and fracture half-length. Typical ranges of matrix parameters have been reviewed. Sensitivity analysis have been conducted to analyze the effect of the above factors on the production performance of SGRs. Through comparison, it can be found that hydraulic fracture

Phlebotomine sand flies are distributed across nearly all faunal regions of the world, represented by over 800 species, of which many are important vectors of human pathogens. Brazil is currently faced with the expansion and urbanization of leishmaniases, with an increase in the numbers of human cases and seropositive dogs in various medium-sized to large cities. The objective of the current study was to survey the phlebotomine sand fly species in an area endemic for American cutaneous leishmaniasis (ACL) and American visceral leishmaniasis (AVL), i.e., the municipal district of Santa Luzia, lying within the metropolitan region of Belo Horizonte in the Brazilian State of Minas Gerais. Sand flies were collected monthly in 2004-2005 using modified Falcão light traps hung in the peridomiciles of houses and surrounding wooded areas in the district of Baronesa. A total of 1,552 sand flies belonging to seven species was collected, and an interesting pattern of the distribution of the most abundant species relative to the sampling locality was revealed. In the wooded areas Lutzomyia whitmani (Antunes & Coutinho) predominated, whereas in the urban area Lutzomyia longipalpis (Lutz & Neiva) was the most abundant species. These results indicate two possible epidemiological patterns of Leishmania transmission in Santa Luzia: one for American cutaneous leishmaniasis associated predominantly with wooded areas, and another for AVL, with transmission principally occurring around human habitations.

The scope of this study is to identify the factors that influence the consumer's decision when buying medicine. Prior to the Generics Act (Lei dos Genéricos), consumers had at their disposal two product purchase options in the private market, namely buying a reference drug and a similar one. Generic drugs are part of a public policy which was intended to broaden access to medication by the general population at more accessible costs, while maintaining the same quality as the reference drug, as ensured by bioequivalence tests from the national health surveillance agency ANVISA. Nevertheless, a question arises as to whether the potential consumer knows the difference between generic, similar and reference drugs, especially when taking into account the decision at the moment of purchase. In order to fulfill the proposed objective, a survey was conducted with 403 residents in Belo Horizonte, Brazil. The data gathered was tabulated and analyzed using factor analysis and crosstab. The results made it possible to infer that there is a strong predisposition among consumers to accept the suggestions of the pharmacists and/or salesman, and a significant portion of the population is confused at the moment of purchase.

A cross-sectional qualitative study was conducted to establish the perceptions of 77 guardians of preschool children enrolled in a Child Day Care Center in Belo Horizonte/Minas Gerais State, regarding what is a healthy diet and the difficulties faced in having a healthy diet. The instrument used was a pretested semi-structured questionnaire containing leading questions obtained in face-to-face interviews. For data analysis, the Collective Subject Discourse technique was used, which elicited data organization of a verbal nature. It was revealed that the guardians have a notion of what healthy diet is, however their answers implied inadequate eating habits. They attributed insufficient financial resources, lack of time and ingrained eating habits as being the main difficulties in having a healthy diet. These three difficulties are the reasons given by some guardians who do not believe they have a healthy diet. The conclusion drawn is that the guardians need to have a better diet, because their eating habits influence their children's eating habits. These findings revealed the need for food and nutrition education strategies to enable the guardians to recognize and have a healthy diet.

Dengue is a widely spread arboviral disease in tropical and subtropical regions of the world. Dengue fever presents clinical characteristics similar to other febrile illness. Thus laboratory diagnosis is important for adequate management of the disease. The present study was designed to evaluate the diagnostic performance of real-time PCR and serological methods for dengue in a real epidemic context. Clinical data and blood samples were collected from consecutive patients with suspected dengue who attended a primary health care unit in Belo Horizonte, Brazil. Serologic methods and real-time PCR were performed in serum samples to confirm dengue diagnosis. Among the 181 consecutive patients enrolled in this study with suspected dengue, 146 were considered positive by serological criteria (positive NS1 ELISA and/or anti-dengue IgM ELISA) and 138 were positive by real-time PCR. Clinical criteria were not sufficient for distinguishing between dengue and non-dengue febrile illness. The PCR reaction was pre-optimized using samples from patients with known viral infection. It had similar sensitivity compared to NS1 ELISA (88% and 89%, respectively). We also evaluated three commercial lateral flow immunochromatographic tests for NS1 detection (BIOEASY, BIORAD and PANBIO). All three tests showed high sensitivity (94%, 91% and 81%, respectively) for dengue diagnosis. According to our results it can be suggested that lateral flow tests for NS1 detection are the most feasible methods for early diagnosis of dengue. Copyright © 2013 Elsevier B.V.

The Belo Monte hydropower plant's low generation cost is among the arguments used by Centrais Eletricas do Norte do Brazil (ELETRONORTE), a Brazilian state electric utility, to make possible its construction. This paper shows that the generation cost presented by ELETROBRAS is very low in relation to the world pattern of cost and probably unrealistic. It also shows that the generation cost cannot be used separately to determine the Belo Monte dam's economic feasibility. There is the need to include other costs, such as: socio environmental degradation and control, financial compensation for using the hydraulic resources, transmission and thermal backup stations, beyond, evidently, generation cost for assuring the credibility of the Belo Monte hydropower plant's economic analysis.

The objective of this study is to establish the prevalence of dysphonia and associated factors in public school female teachers working in Belo Horizonte. This cross-sectional study was conducted on a random sample of schools between May 2004 and July 2005. There were 2103 elementary education daytime teachers from 83 schools included in the study. Self-applied questionnaires were used for data collection. These included questions on social and demographic matters, general health and mental health (General Health Questionnaire-12 [GHQ-12]), the environment and organization of work, and voice-related aspects. The variable dysphonia was classified as absent, possible, or probable based on the association between frequency of fatigue when speaking and worsened voice quality during the past 15 days. Multinomial logistic regression was used to analyze factors independently associated with dysphonia in each response subgroup and in total. One third of the female teachers did not report voice symptoms during the past 15 days (33%). The prevalence of probable dysphonia was 15%, and the prevalence for possible dysphonia was 52%. Factors associated with probable dysphonia were presence of recent upper airway problems (odds ratio [OR]=5.95, 95% confidence interval [CI]=4.06-8.71), problems at work because of voice (OR=65.30, 95% CI=19.33-220.59), other activities with intense voice use (OR=1.71, 95% CI=1.08-2.71), high noise levels (OR=2.55, 95% CI=1.72-3.76), poor ventilation in the classroom (OR=2.00, 95% CI=1.24-3.22), current mental disorder (OR=3.20, 95% CI=2.18-4.70), sedentary life style (OR=1.94, 95% CI=1.21-3.09), and marriage (OR=1.70, 95% CI=1.16-2.47). Associations between probable dysphonia, poor working conditions, health-related aspects, and professional jeopardy indicate the complexity of dysphonia in female teachers and the need for collective intervention strategies.

A well completion scheme currently in use in a thick, large, elongated carbonate anticline Middle-East oil reservoir is described. This method of well completion calls for a combination of an open hole horizontal section penetrating the top 10 feet of the reservoir and a cased or undisturbed vertical segment through the thick formation. The horizontal section is used for producing and the vertical segment is used for monitoring purposes. Field experience and supported reservoir simulation exercises have shown that the horizontal application is superior to conventional vertical completion both from the economic and from the sweep point of view. 4 refs., 12 figs.

Human beings are exposed to ionizing radiation from many natural sources. Radon and its progeny have been recognized as the most important contributors to the natural radioactivity dose, accounting for about half of all human exposure to ionizing radiation. Radon is a α-radioactive noble gas derived from the natural series of uranium and thorium, which occurs in a wide concentration range in all geological materials, especially, in rocks, soils and waters. By diffusion and convection, radon migrates from the rocks and soils to atmosphere and through fissures, pipes and holes it may enter the dwellings and other buildings. Another important radon source in dwellings is its emanation from the construction material. The radon progeny concentration in dwellings has been receiving considerable global attention due to its potential effect in causing lung cancer if it deposited in upper respiratory tract when inhaled. This work presents radon concentration distribution in dwellings in Metropolitan Region of Belo Horizonte - RMBH. The geological settings of the area are Archean rocks of Granitic Gneissic Complex and of metasediments sequences of the great Precambrian unit of the Iron Quadrangle of Minas Gerais, Brazil. Radon concentration measurements were carried out with continuous detector AlphaGUARD PQ200PRO (Genitron), in passive mode and with passive detectors E-PERM Electrets Ion Chamber-EIC. The radon progeny concentration was carried out with a solid state alpha spectroscope, the DOSEman PRO (Sarad). It was found an indoor radon concentration varying in a large range from 4 to 2664,0 Bq.m"-"3, with an average value of 108.0 Bq.m"-"3, median of 70 Bq.m"-"3, geometric mean equal to 76 Bq.m"-"3 and standard deviation of 170 Bq.m"-"3. About 15% of the results are over the United States Environmental Protection Agency (U.S. EPA) actions level, which is 148 Bq.m"-"3.The equilibrium factor between radon and its progeny were determined in dwellings, as 0.3 in average

Resolution of reservoir scale electrical anisotropy from marine CSEM data

Energy Technology Data Exchange (ETDEWEB)

Brown, V.; Hoversten, G.M.; Key, K.; Chen, J.

2011-10-01

A combination of 1D and 3D forward and inverse solutions is used to quantify the sensitivity and resolution of conventional controlled source electromagnetic (CSEM) data collected using a horizontal electric dipole source to transverse electrical anisotropy located in a deep-water exploration reservoir target. Since strongly anisotropic shale layers have a vertical resistivity that can be comparable to many reservoirs, we examine how CSEM can discriminate confounding shale layers through their characteristically lower horizontal resistivity. Forward modeling demonstrates that the sensitivity to reservoir level anisotropy is very low compared to the sensitivity to isotropic reservoirs, especially when the reservoir is deeper than about 2 km below the seabed. However, for 1D models where the number of inversion parameters can be fixed to be only a few layers, both vertical and horizontal resistivity of the reservoir can be well resolved using a stochastic inversion. We find that the resolution of horizontal resistivity increases as the horizontal resistivity decreases. We show that this effect is explained by the presence of strong horizontal current density in anisotropic layers with low horizontal resistivity. Conversely, when the reservoir has a vertical to horizontal resistivity ratio of about 10 or less, the current density is vertically polarized and hence has little sensitivity to the horizontal resistivity. Resistivity anisotropy estimates from 3D inversion for 3D targets suggest that resolution of reservoir level anisotropy for 3D targets will require good a priori knowledge of the background sediment conductivity and structural boundaries.

A retrospective case-control study was carried out at the HIV outpatient clinic of the Universidade Federal de Minas Gerais in Belo Horizonte. We reviewed the demographic, social-economical and medical data of 477 HIV-infected individuals evaluated from 1985 to 1996. The variables were submitted to an univariate and stratified analysis. Aids related complex (ARC, past history of pneumonia, past history of hospitalization, CD4 count and no antiretroviral use were identified as possible effect modifiers and confounding variables, and were submitted to logistic regression analysis by the stepwise method. ARC had an odds ratio (OR of 3.5 (CI 95% - 1.2-10.8 for tuberculosis development. Past history of pneumonia (OR 1.7 - CI 95% 0.6-5.2 and the CD4 count (OR 0.4 - CI 0.2-1.2 had no statistical significance. These results show that ARC is an important clinical surrogate for tuberculosis in HIV-infected patients. Despite the need of confirmation in future studies, these results suggest that the ideal moment for tuberculosis chemoprophylaxis could be previous to the introduction of antiretroviral treatment or even just after the diagnosis of HIV infection.

We conducted a survey of the conditions of radiation protection, radiographic techniques, dose and risk for pediatric patients undergoing chest X-rays exams in a children's hospital in Belo Horizonte-MG, Brazil. From a total of 125 chest exams (projections AP and PA) were noted the patient data (gender, weight, and age) and parameters of radiographic technique (kV, mAs and distance focus-skin). I was also evaluated the working procedures and the conditions of radiation protection. The values of input air kerma (K a,e ) and effective dose (E) were determined using the DoseCal software developed by Radiological Protection Center of Saint Georges's Hospital in London. With respect to the procedures and conditions for radiation protection, many aspects of Portaria 453 are not considered. The use of radiographic techniques with high values of mAs and low voltage values are not according with the quality criteria adopted by the European Community (EC). The values of Ka for patients aged 1 to 5 years varied between 51 μGy and 64 μGy, below the reference levels proposed by the EC. For patients over 5 years old, the values of Ka were substantially higher than those for other patients. The results allow to conclude that there is a need for optimization of the procedures adopted in order to reduce the dose and the risk to patients

Highlights: • Depressurization and thermal co-stimulation using horizontal well were proposed. • 3D stimulation showed that gas release rate was 3 × 10 5 m 3 per day within 450 days. • 2D stimulation showed that Class 3 hydrates could be dissociated within 8500 days. • 2D Simulation showed that heat flow was 1620 W lasting 1500 days, and decreased fast. • 1.1× 10 5 kg water was collected within 2000 days and then no more water was produced. - Abstract: Class 3 hydrate reservoirs exploiting using horizontal well by depressurization and thermal co-stimulation was simulated using the HydarteResSim code. Results showed that more than 20% of hydrates in the reservoirs had been dissociated within 450 days at the well temperature of 42 °C and well pressure of 0.1P 0 , 0.2P 0 (P 0 is the initial pressure of the reservoirs, simplifying 42 °C and 0.1P 0 , 42 °C and 0.2P 0 ). While the production behavior of 42 °C and 0.5P 0 , 42 °C and 0.8P 0 were not so exciting. In order to understand the production character of the well in long term, the cross section of 1 m length reservoirs was simulated. Simulation results showed that 4.5 × 10 5 m 3 gas would be collected within 4500 days and 1.1 × 10 6 kg water could be produced within 1500 days in the well at 42 °C and 0.1P 0 . 3.5 × 10 5 m 3 gas would be collected within 8500 days and 1.1 × 10 6 kg water could be produced within 1500 days in the well at 42 °C and 0.2P 0 . The heat flow was 1620 W at the beginning and then decreased rapidly in the two cases. For reservoirs of 1495.2 m in length, about 6.7 × 10 8 m 3 and 5.3 × 10 8 m 3 gas would be collected in the well corresponding to conditions of 42 °C and 0.1P 0 , and 42 °C and 0.2P 0

Highlights: • A numerical model of the 950–1350 m fractured granite reservoir through horizontal wells is established. • Desirable electricity production performance can be obtained under suitable conditions. • The system attains an electric power of 26.9–24.3 MW with an efficiency of about 50.10–22.39. • Electric power mainly depends on water production rate and injection temperature. • Higher permeability within a certain range is favorable for electricity generation. - Abstract: Deep geological exploration indicates that there is a high-temperature fractured granite reservoir at depth of 950–1350 m in well ZK4001 in the north of Yangbajing geothermal field, with an average temperature of 248 °C and a pressure within 8.01–11.57 MPa. In this work, we evaluated electricity generation potential from this fractured granite reservoir by water circulating through three horizontal wells, and analyzed main factors affecting the performance and efficiency through numerical simulation. The results show that in the reference case the system attains a production temperature of 248.0–235.7 °C, an electrical power of 26.9–24.3 MW, an injection pressure of 10.48–12.94 MPa, a reservoir impedance of 0.07–0.10 MPa/(kg/s), a pump power of 0.54–1.08 MW and an energy efficiency of 50.10–22.39 during a period of 20 years, displaying favorable production performance. Main factors affecting the production performance and efficiency are reservoir permeability, water production rate and injection temperature; within certain ranges increasing the reservoir permeability or adopting more reasonable water production rate or injection temperature will obviously improve the system production performance.

The increasing expansion of compounding pharmacy associated with several reports on variances in the quality of compounded drugs demonstrates the need for verification of quality, safety and efficacy of these products. In this work, physical and chemical analyzes were performed to evaluate the quality of some capsules manipulated enalapril and simvastatin, acquired in five pharmacies in Belo Horizonte /Brazil. Among the analyzes are pharmacopoeial tests for appearance, identification, determination of weight, content, related compounds and uniformity of dosage units, and was also performed neutron activation analysis for the determination of inorganic impurities in drugs sampled. The results showed that 60% of the samples were unsatisfactory for pharmacopoeial tests. The contents of the capsules sampled for individual testing unit dose uniformity between 0% and 136.2%. This test is important in evaluating the quality, which influences the safety and efficacy of drug treatment, since it allows you to check if the product contains the proper dosage and necessary for successful pharmacotherapy. On the other hand, underdosing can lead to reduced or absent desired therapeutic response, and overdoses can provide an undesirable effects and even toxic. The concentration of inorganic impurities was considered to be relatively small. However, no specific limits for some chemical elements in medicine hamper a better thread. In addition, further studies must be performed to assess chronic exposure to low concentrations of inorganic impurities, since drugs can be continuously used, and other sources of exposure must also be considered in order to evaluate the risk. The problems related to the quality and safety of compounded drugs are still reality in the country and reveal a serious public health problem, especially regarding the lack of uniformity between the unit doses of medications. It is suggested that the competent authorities to sanitary products, propose changes in

2018-01-01

Full Text Available A mathematical model for multistage hydraulically fractured horizontal wells (MFHWs in tight oil and gas reservoirs was derived by considering the variations in the permeability and porosity of tight oil and gas reservoirs that depend on formation pressure and mixed fluid properties and introducing the pseudo-pressure; analytical solutions were presented using the Newman superposition principle. The CPU-GPU asynchronous computing model was designed based on the CUDA platform, and the analytic solution was decomposed into infinite summation and integral forms for parallel computation. Implementation of this algorithm on an Intel i5 4590 CPU and NVIDIA GT 730 GPU demonstrates that computation speed increased by almost 80 times, which meets the requirement for real-time calculation of the formation pressure of MFHWs.

Full Text Available This paper presents a study of characteristic value method of well test analysis for horizontal gas well. Owing to the complicated seepage flow mechanism in horizontal gas well and the difficulty in the analysis of transient pressure test data, this paper establishes the mathematical models of well test analysis for horizontal gas well with different inner and outer boundary conditions. On the basis of obtaining the solutions of the mathematical models, several type curves are plotted with Stehfest inversion algorithm. For gas reservoir with closed outer boundary in vertical direction and infinite outer boundary in horizontal direction, while considering the effect of wellbore storage and skin effect, the pseudopressure behavior of the horizontal gas well can manifest four characteristic periods: pure wellbore storage period, early vertical radial flow period, early linear flow period, and late horizontal pseudoradial flow period. For gas reservoir with closed outer boundary both in vertical and horizontal directions, the pseudopressure behavior of the horizontal gas well adds the pseudosteady state flow period which appears after the boundary response. For gas reservoir with closed outer boundary in vertical direction and constant pressure outer boundary in horizontal direction, the pseudopressure behavior of the horizontal gas well adds the steady state flow period which appears after the boundary response. According to the characteristic lines which are manifested by pseudopressure derivative curve of each flow period, formulas are developed to obtain horizontal permeability, vertical permeability, skin factor, reservoir pressure, and pore volume of the gas reservoir, and thus the characteristic value method of well test analysis for horizontal gas well is established. Finally, the example study verifies that the new method is reliable. Characteristic value method of well test analysis for horizontal gas well makes the well test analysis

Toxic metals, such as Ni, V, Zn, Cu, Cr, Mn and metalloids as As and Se and their compounds are mainly associated with the smaller diameter particulates present in the atmospheric aerosols. This fact is important, principally, when it concerns public health, because this is considered the breathable fraction of particles that can penetrate deeply into the lungs and cause damage to the alveoli. Once in the atmosphere the concentrations of trace metals, in general, show very low levels, thus the determination of the elementary composition of those particles requires the use of appropriate analytical techniques such as Particle Induced X-Ray Emission (PIXE), Neutron Activation Analysis (NAA) and X-Rays Fluorescence spectrometry (XRF), among others. The main objective of this study was the identification of the generating sources of gross (PM 10 ) and fine (PM 2.5 ) particles present in the atmospheric aerosols of the metropolitan region of Belo Horizonte. Neutron Activation Analyses by k 0 -method (k0NAA) combined with energy dispersed by X-ray fluorescence was used to measurement of the concentration of trace elements present in each sample. High levels of particulate concentrations, especially PM 2.5 , were measured during the sampling period. In general, the air quality varied from Reasonable to Inadequate. The receptor model used to assist in the identification of the main emission sources was the Principal Components Analysis. The results showed that the main elements presents in particulate inhalable matter (PM 2.5 and PM 10 ) were Ag, Al, As, Au, Ba, Br, Ca, Cl, Cr, Cu, Fe, K, Mn, Na, S, Sb, Sc, Si, Ti, W and Zn. The results for multi-variable analyses shown clearly four pollutant sources, these being: vehicular emissions; resuspended soil/asphalt powder; secondary aerosols associated with emission of SO 2 and industrial emissions associated with fossil oil burning.

To investigate whether social relations, sociodemographic characteristics, lifestyle, and health conditions are associated with health-related quality of life (HRQOL) among elderly persons living in regions classified as high vulnerable in terms of health. A cross-sectional study conducted with a population-based random sample of 366 elderly (≥ 60 years of age) persons registered at a primary health-care unit in Belo Horizonte, Minas Gerais, Brazil. HRQOL was measured using the Medical Outcomes Study 12-Item Short-Form Health Survey (SF-12) and the scores obtained in the physical component score (PCS) and mental component score (MCS) were our response variables. Social relations, sociodemographic characteristics, lifestyle, and health conditions were considered our groups of explanatory variables. Multiple linear regression models were used for the analysis. In the final multivariate models, we found that elevated number of diagnosis of chronic diseases, and being bedridden for the last 15 days were variables associated with worse PCS and MCS. However, lack of education, dissatisfaction with personal relationships, lack of support and help when bedridden or to go to the doctor, and to prepare meals were associated with worse HRQOL only in MCS. Participants who reported black race/color, absence of work activity, lack of physical activity, no alcohol consumption, and hospitalization in the last 12 months had worse HRQOL only in PCS. In addition to the aspects related to social adversity, lifestyle, and health conditions, some functional aspects of social relations were important for understanding the HRQOL in elderly persons living in social vulnerability.

A solution obtained by using the boundary element method to simulate pressure behaviour of horizontal wells in complicated reservoir-wellbore configurations is presented. Three different types of well bore and reservoir models were studied, i.e. a snake-shaped horizontal wellbore intersecting a two-layer reservoir with cross flow, a horizontal well in a three-layer reservoir with cross flow, and a vertical well intersecting a two-layer reservoir without cross flow. In each case, special attention was paid to the influence of wellbore inclination angle, the distance from the wellbore to the different boundaries and the permeability ratio. Performance of each of these types of wells are discussed. 9 refs., 18 figs.

A participação das mulheres no mercado de trabalho vem se consolidando com o passar dos anos, com destaque para a área da educação, fazendo com que esse processo de inserção do gênero feminino seja constante e gradativo. No entanto, ao assumir cargos na escala hierárquica, principalmente nas instituições de ensino superior, percebe-se que, pouco a pouco, seus lugares passam a ser ocupados por homens que, em grande parte das situações, estão no comando e são os responsáveis pelas principais tomadas de decisões que dizem respeito ao futuro das instituições. Neste estudo, três diretoras de instituições de ensino superior privadas pertencentes a grupos educacionais localizados em Belo Horizonte, Minas Gerais, foram convidadas a compartilhar um pouco de sua trajetória rumo ao empoderamento. Constatou-se, ao final do estudo, que, embora as três diretoras estejam adiantadas em seu processo de empoderamento, situações cotidianas mostram a existência de um “teto de vidro” construído por meio de um preconceito velado no ramo educacional.

In this work, physical and chemical analyzes were performed to evaluate the quality of some capsules manipulated enalapril and simvastatin, acquired in five pharmacies in Belo Horizonte /Brazil. Among the analyzes are pharmacopoeial tests for appearance, identification, determination of weight, content, related compounds and uniformity of dosage units, and was also performed neutron activation analysis for the determination of inorganic impurities in drugs sampled. The results showed that 60% of the samples were unsatisfactory for pharmacopoeial tests. The contents of the capsules sampled for individual testing unit dose uniformity between 0% and 136.2%. This test is important in evaluating the quality, which influences the safety and efficacy of drug treatment, since it allows you to check if the product contains the proper dosage and necessary for successful pharmacotherapy. On the other hand, underdosing can lead to reduced or absent desired therapeutic response, and overdoses can provide an undesirable effects and even toxic. The concentration of inorganic impurities was considered to be relatively small. However, no specific limits for some chemical elements in medicine hamper a better thread. In addition, further studies must be performed to assess chronic exposure to low concentrations of inorganic impurities, since drugs can be continuously used, and other sources of exposure must also be considered in order to evaluate the risk. The problems related to the quality and safety of compounded drugs are still reality in the country and reveal a serious public health problem, especially regarding the lack of uniformity between the unit doses of medications.

The Eva South Morrow Sand Unit is located in western Texas County, Oklahoma. The field produces from an upper Morrow sandstone, termed the Eva sandstone, deposited in a transgressive valley-fill sequence. The field is defined as a combination structural stratigraphic trap; the reservoir lies in a convex up -dip bend in the valley and is truncated on the west side by the Teepee Creek fault. Although the field has been a successful waterflood since 1993, reservoir heterogeneity and compartmentalization has impeded overall sweep efficiency. A 4.25 square mile high-resolution, three component three-dimensional (3C3D) seismic survey was acquired in order to improve reservoir characterization and pinpoint the optimal location of a new horizontal producing well, the ESU 13-H.

Belo Horizonte is the sixth most populous city in Brazil, has the third largest fleet of vehicles and it is close to large mineralogical reserves, such the Quadrilátero Ferrífero. These factors, coupled with the industrial growth and civil construction, raise questions about society regarding ambient air quality. A historically problematic contaminant is the particulate matter (PM), a mixture of solid and liquid particles in suspension that generate environmental damage and human health. These particles can cause from a simple infection to death, being their dimension a fundamental factor to evaluate the impact caused. In this context, this research investigated the air quality due to PM10 (particles less than 10 microns) in a high traffic flow of Minas Gerais capital, Presidente Antônio Carlos Avenue. This avenue is one of the main accesses to the region of Pampulha, an area of great tourist and sporting relevance of the city and has undergone works of duplication and implementation of exclusive lanes for public transport buses due to the realization of the 2014 World Cup. Involved monitoring in the avenue in the year 2014 in order to collect the PM10 present in the ambient air. The characterization of PM10 occurred with the use of the X-ray diffraction technique, one of the main tools of mineralogical characterization, due to its simplicity, speed and reliability of the obtained results. The minerals detected by the analysis were evaluated for their possible origin, generating information for the evaluation of PM10 emitting sources that are fundamental for the management of air quality in the city.

In this context, this research investigated the air quality due to PM10 (particles less than 10 microns) in a high traffic flow of Minas Gerais capital, Presidente Antônio Carlos Avenue. This avenue is one of the main accesses to the region of Pampulha, an area of great tourist and sporting relevance of the city and has undergone works of duplication and implementation of exclusive lanes for public transport buses due to the realization of the 2014 World Cup. Involved monitoring in the avenue in the year 2014 in order to collect the PM10 present in the ambient air. The characterization of PM10 occurred with the use of the X-ray diffraction technique, one of the main tools of mineralogical characterization, due to its simplicity, speed and reliability of the obtained results. The minerals detected by the analysis were evaluated for their possible origin, generating information for the evaluation of PM10 emitting sources that are fundamental for the management of air quality in the city.

The research of the sentinel lymph node in early breast cancer, an already worldwide established method, was standardized at the teaching hospital 'Hospital das Clinicas' in Belo Horizonte (MG, Brazil). This standardization was carried out from December 2000 through December 2002, in which 39 patients were included in a learning curve and method validation. The applied methodology is based on the combination of a lymphoscintillography and the blue stain. A periareolar colloid 99m Tc injection was given 24 hours before the surgery. The blue dye was injected in the peritumoral region during the surgery. The sentinel lymph node was identified by the blue color pattern of the lymph node and by the use of a portable gamma probe detector. Radioactive contamination was evaluated before, during and after the surgery. The measurement of the radioactivity of the breast area was taken by using a GM detector and an ionization chamber on a humid piece of gauze (passed on the breast area), from which the radioactivity was recorded as well as the gloves used during the surgery, and the gauzes with contaminated blood. The sentinel lymph node identification rate was found to be 95%, there was a false negative rate of 4,8% and a predictive negative value (PNV) of 94%. The identification figures, the predictive negative value and the false negative rate were similar to the figures found in technical literature. The technique of the biopsy of the sentinel lymph node (BSL) is the method chosen for staging patients with invasive breast cancer and with clinically negative results for the armpit. The combined method using radio-colloid and the stain is the most indicated. There is a minimum radio isotopic contamination and there is scarcely any danger for the patient or the medical staff involved in the procedure. (author)

A Mathematical Pressure Transient Analysis Model for Multiple Fractured Horizontal Wells in Shale Gas Reservoirs

2018-01-01

Full Text Available Multistage fractured horizontal wells (MFHWs have become the main technology for shale gas exploration. However, the existing models have neglected the percolation mechanism in nanopores of organic matter and failed to consider the differences among the reservoir properties in different areas. On that account, in this study, a modified apparent permeability model was proposed describing gas flow in shale gas reservoirs by integrating bulk gas flow in nanopores and gas desorption from nanopores. The apparent permeability was introduced into the macroseepage model to establish a dynamic pressure analysis model for MFHWs dual-porosity formations. The Laplace transformation and the regular perturbation method were used to obtain an analytical solution. The influences of fracture half-length, fracture permeability, Langmuir volume, matrix radius, matrix permeability, and induced fracture permeability on pressure and production were discussed. Results show that fracture half-length, fracture permeability, and induced fracture permeability exert a significant influence on production. A larger Langmuir volume results in a smaller pressure and pressure derivative. An increase in matrix permeability increases the production rate. Besides, this model fits the actual field data relatively well. It has a reliable theoretical foundation and can preferably describe the dynamic changes of pressure in the exploration process.

Coombs, Steven F.

1999-01-01

The main objective of this project is to devise an effective redevelopment strategy to combat producibility problems related to the Repetto turbidite sequences of the Carpinteria Field. The lack of adequate reservoir characterization, high-water cut production, and scaling problems have in the past contributed to the field's low productivity. To improve productivity and enhance recoverable reserves, the following specific goals are proposed: (1) Develop an integrated database of all existing data from work done by the former ownership group. (2) Expand reservoir drainage and reduce sand problems through horizontal well drilling and completion. (3) Operate and validate reservoirs' conceptual model by incorporating new data from the proposed trilateral well. (4) Transfer methodologies employed in geologic modeling and drilling multilateral wells to other operators with similar reservoirs

Partidas, C. [PDVSA Exploration and Production (Venezuela)

1998-12-31

Horizontal drilling in the mature Lake Maracaibo field in Venezuela as a means of stimulating production are discussed. The Miocene sand where the horizontal well technology was applied, presented a number of intervals of unconsolidated sand of varied continuity, pay intervals at ten to twenty feet thickness, and reservoir pressures mostly at hydrostatic or below hydrostatic values. This paper evaluates a horizontal drilling program in the Lagunallis Lago Production Unit of Maracaibo, involving 91 wells to date (since 1995). When assessed in economic terms, results indicate that horizontal wells are a better economic alternative than vertical wells. The same results also showed that drainage from thin sand reservoirs resulted in better production with horizontal well technology than production from vertical wells. Payout was less than two years for 50 per cent of the horizontal wells while 40 per cent had payouts of between two and four years. Profit to investment ratio was greater than two in the case of about 70 per cent of the horizontal wells drilled in 1996. 2 tabs., 10 figs.

The purpose of this project was to economically design an optimum carbon dioxide (CO{sub 2}) flood for a mature waterflood nearing its economic abandonment. The original project utilized advanced reservoir characterization and CO{sub 2} horizontal injection wells as the primary methods to redevelop the South Cowden Unit (SCU). The development plans; project implementation and reservoir management techniques were to be transferred to the public domain to assist in preventing premature abandonment of similar fields. The Unit was a mature waterflood with water cut exceeding 95%. Oil must be mobilized through the use of a miscible or near-miscible fluid to recover significant additional reserves. Also, because the unit was relatively small, it did not have the benefit of economies of scale inherent in normal larger scale projects. Thus, new and innovative methods were required to reduce investment and operating costs. Two primary methods used to accomplish improved economics were use of reservoir characterization to restrict the flood to the higher quality rock in the unit and use of horizontal injection wells to cut investment and operating costs. The project consisted of two budget phases. Budget Phase I started in June 1994 and ended late June 1996. In this phase Reservoir Analysis, Characterization Tasks and Advanced Technology Definition Tasks were completed. Completion enabled the project to be designed, evaluated, and an Authority for Expenditure (AFE) for project implementation submitted to working interest owners for approval. Budget Phase II consisted of the implementation and execution of the project in the field. Phase II was completed in July 2001. Performance monitoring, during Phase II, by mid 1998 identified the majority of producing wells which under performed their anticipated withdrawal rates. Newly drilled and re-activated wells had lower offtake rates than originally forecasted. As a result of poor offtake, higher reservoir pressure was a concern

Oriented cluster perforating technology and its application in horizontal wells

2016-11-01

Full Text Available An oriented cluster perforating technology, which integrates both advantages of cluster and oriented perforating, will help solve a series of technical complexities in horizontal well drilling. For realizing its better application in oil and gas development, a series of technologies were developed including perforator self-weight eccentricity, matching of the electronic selective module codes with the surface program control, axial centralized contact signal transmission, and post-perforation intercluster sealing insulation. In this way, the following functions could be realized, such as cable-transmission horizontal well perforator self-weight orientation, dynamic signal transmission, reliable addressing & selective perforation and post-perforation intercluster sealing. The combined perforation and bridge plug or the multi-cluster perforation can be fulfilled in one trip of perforation string. As a result, the horizontal-well oriented cluster perforating technology based on cable conveying was developed. This technology was successfully applied in unconventional gas reservoir exploitation, such as shale gas and coalbed methane, with accurate orientation, reliable selective perforation and satisfactory inter-cluster sealing. The horizontal-well oriented cluster perforating technology benefits the orientation of horizontal well drilling with a definite target and direction, which provides a powerful support for the subsequent reservoir stimulation. It also promotes the fracturing fluid to sweep the principal pay zones to the maximum extent. Moreover, it is conductive to the formation of complex fracture networks in the reservoirs, making quality and efficient development of unconventional gas reservoirs possible.

Full Text Available O trabalho em equipe é considerado um importante pressuposto para a reorganização do processo de trabalho. Essa modalidade visa uma abordagem mais integral, resolutiva e efetiva frente às atividades coletivas e interdisciplinares. Para a equipe de enfermagem este tipo de trabalho é de fundamental importância e depende de uma liderança capaz de gerenciar os conflitos e anseios que por ventura surgirem. Tal liderança, muitas vezes, eleita pelo próprio grupo, envolve a capacidade de influenciar pessoas. Assim, esse estudo tem por objetivo analisar o papel das lideranças e sua efetividade para o trabalho no interior de uma equipe assistencial de enfermagem. Os sujeitos da pesquisa em questão são quatro técnicos de enfermagem do setor de atendimento de urgência e emergência de um hospital geral de grande porte, localizado em Belo Horizonte. Uma vez que a questão da liderança apresenta-se, na maioria das vezes, de forma subjetiva, não sendo possível analisá-la em sua plenitude em questionários fechados, optou-se pela utilização da observação participante como principal ferramenta metodológica para coleta dos dados da pesquisa. Com o estudo, pode-se observar que a equipe, de uma forma geral, possui um bom entrosamento e uma postura ético-profissional pertinente ao desenvolvimento da assistência e do cuidado frente ao paciente. No entanto, a observação participante nos revelou a existência de uma liderança autoritária exercida por um dos membros da equipe. Apesar da insatisfação gerada nos demais membros da equipe, essa postura não prejudica o desenvolvimento do trabalho.

Economics of Developing Hot Stratigraphic Reservoirs

2014-09-01

Stratigraphic geothermal reservoirs at 3 – 4 km depth in high heat-flow basins are capable of sustaining 100 MW-scale power plants at about 10 c/kWh. This paper examines the impacts on the levelized cost of electricity (LCOE) of reservoir depth and temperature, reservoir productivity, and drillhole/casing options. For a reservoir at 3 km depth with a moderate productivity index by hydrothermal reservoir standards (about 50 L/s/MPa, 5.6 gpm/psi), an LCOE of 10c/kWh requires the reservoir to be at about 200°C. This is the upper temperature limit for pumps. The calculations assume standard hydrothermal drilling costs, with the production interval completed with a 7 inch liner in an 8.5 inch hole. If a reservoir at 4 km depth has excellent permeability characteristics with a productivity index of 100 L/s/MPa (11.3 gpm/psi), then the LCOE is about 11 c/kWh assuming the temperature decline rate with development is not excessive (< 1%/y, with first thermal breakthrough delayed by about 10 years). Completing wells with modest horizontal legs (e.g. several hundred meters) may be important for improving well productivity because of the naturally high, sub-horizontal permeability in this type of reservoir. Reducing the injector/producer well ratio may also be cost-effective if the injectors are drilled as larger holes.

2017-12-01

Full Text Available The objective of this paper is studying the impact of the hydraulic flow unit and reservoir quality index (RQI on pressure profile and productivity index of horizontal wells acting in finite reservoirs. Several mathematical models have been developed to investigate this impact. These models have been built based on the pressure distribution in porous media, depleted by a horizontal well, consist of multi hydraulic flow units and different reservoir quality index. The porous media are assumed to be finite rectangular reservoirs having different configurations and the wellbores may have different lengths. Several analytical models describing flow regimes have been derived wherein hydraulic flow units and reservoir quality index have been included in addition to rock and fluid properties. The impact of these two parameters on reservoir performance has also been studied using steady state productivity index.It has been found that both pressure responses and flow regimes are highly affected by the existence of multiple hydraulic flow units in the porous media and the change in reservoir quality index for these units. Positive change in the RQI could lead to positive change in both pressure drop required for reservoir fluids to move towards the wellbore and hence the productivity index.

Horizontal alternating steam drive process for the Orinoco heavy oil belt in eastern Venezuela

Energy Technology Data Exchange (ETDEWEB)

Edgar A. Fernandez R.; Bashbush, J.L. [Schlumberger, Sugar Land, TX (United States)

2008-10-15

Horizontal alternating steam drive (HASD) processes use single horizontal wells that cyclically switch between injection and production phases. The steam chambers generated by the wells are laterally driven by the pressure differentials created by adjacent producers to form a sweeping front between the wells. This feasibility study assessed the use of HASD processes at a heavy oil reservoir in Venezuela. The study used numerical simulations from a representative reservoir with a 5-horizontal well array to asses the HASD recovery technique under various scenarios. Sensitivity analyses were also conducted to consider the positioning of the horizontal well placement in the reservoir column; different injection sequences; variations in the duration of injection cycles; injection rates; and the lengths of the horizontal reach of the wells. Results of the study suggested that HASD is a suitable alternative for reservoirs with sands in the 20 foot to 50 foot thickness range. HASD achieved average recovery factors of above 20 per cent over a 15 year period, and required fewer wells than steam assisted gravity drainage (SAGD) processes. It was concluded that the wells must be designed to consider the additional thermal stresses resulting the repeated injection and production cycles associated with HASD processes.

The intent of this project was to increase production and extend the economic life of this mature field through the application of advanced reservoir characterization and drilling technology, demonstrating the efficacy of these technologies to other small operators of aging fields. Two study periods were proposed; the first to include data assimilation and reservoir characterization and the second to drill the demonstration well. The initial study period showed that a single tri-lateral well would not be economically efficient in redevelopment of Carpinteria's multiple deep water turbidite sand reservoirs, and the study was amended to include the drilling of a series of horizontal redrills from existing surplus well bores on Pacific Operators' Platform Hogan.

Because of the high prevalence of iron-deficiency anemia in Brazil, individual control measures tend to be ineffective, and fortification of foods with iron is considered the most effective method to fight anemia. To evaluate the effectiveness of fortification of drinking water with iron and vitamin C in the reduction of anemia in children in day-care centers in Belo Horizonte, Brazil. This before-and-after study evaluated 318 children aged 6 to 74 months. Identification data and data on socioeconomic variables were collected; anthropometric and biochemical measurements were performed before and after 5 months of fortification of water with 5 mg of elemental iron and 50 mg of ascorbic acid per liter. The fortified water was used for drinking and cooking at the day-care center. Wilcoxon's nonparametric test was used to evaluate the differences in continuous variables, and McNemar's test was used to compare the prevalence rates of anemia. The prevalence of anemia decreased significantly from 29.3% before fortification to 7.9% at the end of the study, with a significant increase in hemoglobin levels. Reductions in the prevalence rates of stunting and underweight were observed. Fortification of water with iron and vitamin C significantly reduced the prevalence of anemia and improved nutritional status among children attending day-care centers.

Example of drilling a horizontal well in reservoir rock of only four meter thick by using existing casing pipe of low efficiency vertical wells to induce production in the top remaining reservoir is described. The experience shows that drilling horizontal wells laterally in thin bodies of sandstone reservoirs and improve their productivity is a feasible proposition. Productivity will still be low, but it can be improved by well stimulation. 3 refs., 3 figs.

Full Text Available Deep shale gas reservoirs buried underground with depth being more than 3500 m are characterized by high in-situ stress, large horizontal stress difference, complex distribution of bedding and natural cracks, and strong rock plasticity. Thus, during hydraulic fracturing, these reservoirs often reveal difficult fracture extension, low fracture complexity, low stimulated reservoir volume (SRV, low conductivity and fast decline, which hinder greatly the economic and effective development of deep shale gas. In this paper, a specific and feasible technique of volume fracturing of deep shale gas horizontal wells is presented. In addition to planar perforation, multi-scale fracturing, full-scale fracture filling, and control over extension of high-angle natural fractures, some supporting techniques are proposed, including multi-stage alternate injection (of acid fluid, slick water and gel and the mixed- and small-grained proppant to be injected with variable viscosity and displacement. These techniques help to increase the effective stimulated reservoir volume (ESRV for deep gas production. Some of the techniques have been successfully used in the fracturing of deep shale gas horizontal wells in Yongchuan, Weiyuan and southern Jiaoshiba blocks in the Sichuan Basin. As a result, Wells YY1HF and WY1HF yielded initially 14.1 × 104 m3/d and 17.5 × 104 m3/d after fracturing. The volume fracturing of deep shale gas horizontal well is meaningful in achieving the productivity of 50 × 108 m3 gas from the interval of 3500–4000 m in Phase II development of Fuling and also in commercial production of huge shale gas resources at a vertical depth of less than 6000 m.

Brazil's large territory displays significant richness in caves with about 12 thousand caves already recorded. Nevertheless, studies on bats in these environments are extremely scarce and fragmented. This study characterized the chiropteran fauna from two sandstone caves under the influence of the Belo Monte hydroelectric dam (Belo Monte UHE) in Pará, Brazil. The Kararaô and Kararaô Novo caves are located on the same ridge, 250 m apart. Three expeditions were carried out in 2013 and 2014, with a 4- to 5-month interval in between. A total of 589 animals were caught, 246 in the Kararaô cave and 343 in the Kararaô Novo cave. Fifteen species were recorded (13 in each cave) representing 79% similarity. With the exception of Vampyrum spectrum, which is not a cave species, the remaining recorded species were mostly cave bat species. Some species seemed to use the caves seasonally, although the basis of this pattern is still unknown. The most commonly observed species were Pteronotus personatus (dominant in the Kararaô cave), P. parnellii (dominant in the Kararaô Novo cave), and Lionycteris spurrelli, which accounted for 65% of all captures recorded for the two caves. Natalus macrourus is a species recorded in the Kararaô cave that is regionally threatened with extinction. Both caves are less than 500 m from the future reservoir; however, because the Kararaô cave entry is in an area that is lower than the reservoir, it can suffer alterations that would affect its dynamics. This raises great concern about the cave's associated fauna.

This final report describes the progress during the six year of the project on ''Integrated Approach Towards the Application of Horizontal Wells to Improve Waterflooding Performance.'' This report is funded under the Department of Energy's (DOE's) Class I program which is targeted towards improving the reservoir performance of mature oil fields located in fluvially-dominated deltaic deposits. The project involves using an integrated approach to characterize the reservoir followed by drilling of horizontal injection wells to improve production performance. The project was divided into two budget periods. In the first budget period, many modern technologies were used to develop a detailed reservoir management plan; whereas, in the second budget period, conventional data was used to develop a reservoir management plan. The idea was to determine the cost effectiveness of various technologies in improving the performance of mature oil fields.

Lithology-dependent In Situ Stress in Heterogeneous Carbonate Reservoirs

Pham, C. N.; Chang, C.

2017-12-01

Characterization of in situ stress state for various geomechanical aspects in petroleum development may be particularly difficult in carbonate reservoirs in which rock properties are generally heterogeneous. We demonstrate that the variation of in situ stress in highly heterogeneous carbonate reservoirs is closely related to the heterogeneity in rock mechanical property. The carbonate reservoir studied consists of numerous sequential layers gently folded, exhibiting wide ranges of porosity (0.01 - 0.29) and Young's modulus (25 - 85 GPa) depending on lithology. Wellbore breakouts and drilling-induced tensile fractures (DITFs) observed in the image logs obtained from several wells indicate that the in situ state of stress orientation changes dramatically with depth and location. Even in a wellbore, the azimuth of the maximum horizontal stress changes by as much as 60° within a depth interval of 500 m. This dramatic change in stress orientation is inferred to be due to the contrast in elastic properties between different rock layers which are bent by folding in the reservoir. The horizontal principal stress magnitudes are constrained by back-calculating stress conditions necessary to induce the observed wellbore failures using breakout width and the presence of DITFs. The horizontal stresses vary widely, which cannot be represented by a constant stress gradient with depth. The horizontal principal stress gradient increases with Young's modulus of layer monotonically, indicating that a stiffer layer conveys a higher horizontal stress. This phenomenon can be simulated using a numerical modelling, in which the horizontal stress magnitudes depend on stiffness of individual layers although the applied far-field stress conditions are constant. The numerical results also suggest that the stress concentration at the wellbore wall is essentially higher in a stiffer layer, promoting the possibility of wellbore breakout formation. These results are in agreement with our

1998-12-31

Case study of a horizontal well successfully drilled in 1994 by Shell Oil in the Niger Delta is described. The well was drilled with the objectives of improving drainage of the major D3.1 reservoir and appraising the poorly defined eastern flank for structure and fluid content of the overlying D3.0 sand. The well was optimized by 3D reservoir and hydrocarbon modeling of these reservoirs. Combining the development and appraisal objectives in one horizontal well proved to be the optimal solution, both from a cost as well as a production consideration. The well proved up over 50 MMstb of additional reserves. The structural flank proved to be significantly shallower than previously mapped and had a positive effect not only on the D3.0 reserves, but also on the the D3.1. 6 figs.

In the past decade, the use of horizontal well technology has increased significantly in the U.S., contributing to the drilling of 600 to 1000 horizontal oil wells annually. A total of 86 per cent of the existing horizontal wells have been drilled in three formations, the Austin chalk in Texas, the Bakken shale in North Dakota, and the Niobrara in Colorado and Wyoming. A unique analytical system has been developed by the United States Department of Energy, National Petroleum Technology Office (USDOE/NPTO) to assess the potential for greater use of horizontal well technology for other oil resources in other geological formations. The analytical system is designed to be used in association with other enhanced recovery methods that make up the DOE's Total Oil Recovery Information System (TORIS). The DOE/NPTO collaborated with industry to identify the target resource for horizontal well technology and to evaluate its future recovery potential under different economic and technological conditions. This paper provides a national summary of the potential for additional production and reserves with more diverse application of horizontal wells in various types of U.S. oil resources, including the rest of the fractured reservoirs in the Austin chalk, other fractured reservoirs in the north and northwestern states, thin-bed reservoirs, and mature waterflood field. The results were presented in terms of production, reserves and national economic benefits with a full cash-flow analysis at oil prices in the range of $16 to $24 U.S. per bbl. It is estimated that 541 million to 1 billion bbls of new reserves are economically producible at these prices. The reserves estimates pertain to future horizontal wells in known fields only and are in addition to the reserves for the existing wells as of 1 January 1998. Potential production is substantial, ranging from 50 million to 85 million bbl per year by 2004 and then declining at a rate of 8 per cent per year in the following years

Freshwater reservoirs are used for many purposes as hydropower generation, water supply and irrigation. In Brazil, according to the National Energy Balance of 2013, hydropower energy corresponds to 70.1% of the Brazilian demand. Superficial waters (which include rivers, lakes and reservoirs) are the most used source for drinking water supply - 56% of the municipalities use superficial waters as a source of water. The last two years have shown that the Brazilian water and electricity supply is highly vulnerable and that improved management is urgently needed. The construction of reservoirs affects physical, chemical and biological characteristics of the water body, e.g. stratification, temperature, residence time and turbulence reduction. Some water quality issues related to reservoirs are eutrophication, greenhouse gas emission to the atmosphere and dissolved oxygen depletion in the hypolimnion. The understanding of the physical processes in the water body is fundamental to reservoir management. Lakes and reservoirs may present a seasonal behavior and stratify due to hydrological and meteorological conditions, and especially its vertical distribution may be related to water quality. Stratification can control heat and dissolved substances transport. It has been also reported the importance of horizontal temperature gradients, e.g. inflows and its density and processes of mass transfer from shallow to deeper regions of the reservoir, that also may impact water quality. Three dimensional modeling of the heat transport in lakes and reservoirs is an important tool to the understanding and management of these systems. It is possible to estimate periods of large vertical temperature gradients, inhibiting vertical transport and horizontal gradients, which could be responsible for horizontal transport of heat and substances (e.g. differential cooling or inflows). Vossoroca reservoir was constructed in 1949 by the impoundment of São João River and is located near to

Uncertainties in Amazon Hydropower Development: Risk Scenarios and Environmental Issues around the Belo Monte Dam

Full Text Available The Amazon region is the final frontier and central focus of Brazilian hydro development, which raises a range of environmental concerns. The largest project in the Amazon is the planned Belo Monte Complex on the Xingu river. If constructed it will be the second biggest hydroelectric plant in Brazil, third largest on earth. In this study, we analyse the private and social costs, and benefits of the Belo Monte project. Furthermore, we present risk scenarios, considering fluctuations in the project’s feasibility that would result from variations in total costs and power. For our analysis, we create three scenarios. In the first scenario Belo Monte appears feasible, with a net present value (NPV in the range of US$670 million and a rate of return in excess of the 12% discount rate used in this analysis. The second scenario, where we varied some of the project costs and assumptions based on other economic estimates, shows the project to be infeasible, with a negative NPV of about US$3 billion and external costs around US$330 million. We also conducted a risk analysis, allowing variation in several of the parameters most important to the project’s feasibility. The simulations brought together the risks of cost overruns, construction delays, lower-than-expected generation and rising social costs. The probability of a positive NPV in these circumstances was calculated to be just 28%, or there is a 72% chance that the costs of the Belo Monte dam will be greater than the benefits. Several WCD recommendations are not considered in the project, especially those related to transparency, social participation in the discussion, economic analysis and risk assessment, and licensing of the project. This study underscores the importance of forming a participatory consensus, based on clear, objective information, on whether or not to build the Belo Monte dam.

Wireline logging programs are frequently used to evaluate vertical boreholes in shale gas plays. Data logged from the vertical hole are used to define reservoir profiles for the horizontal target window. The horizontal wells are then steered based on gamma ray measurements obtained using correlations against the vertical pilot wells. Logging-while-drilling tools are used in bottom hole assemblies (BHA) to ensure accurate well placement and to perform detailed reservoir characterizations across the target structure. The LWD measurements are also used to avoid hazards and enhance rates of penetration. LWD can also be used to enhance trajectory placement and provide an improved understanding of reservoirs. In this study, LWD measurements were conducted at a shale gas play in order to obtain accurate well placement, formation evaluation, and completion optimization processes. The study showed how LWD measurements can be used to optimize well completion and stimulation plans by considering well positions in relation to geological targets, reservoir property changes, hydrocarbon saturation disparity, and variations in geomechanical properties. 21 refs., 13 figs.

Shale reservoir exploitation requires horizontal hydro-fracturing, often in a multi-stage configuration. Fracture stages are usually evenly spaced along the horizontal well, regardless of reservoir characteristics, even though wireline logs or logging-while-drilling (LWD) methods could be used to determine sweet spots for more cost-effective fracturing locations. This paper aims to show how failure to take into consideration a reservoir's geological properties can lead to less effective exploitation, and then goes on to describe logging techniques, LWD and wireline logs combined, and their usefulness in effectively placing fracturing stages on a reservoir's sweet spots. By studying logs from different LWD and wireline log techniques, such as gamma ray, resistivity, X-ray fluorescence or shockwave sonic measurements for different existing wells, the study shows how sweet spots, where kerogen concentration is higher, with higher porosity, can be determined. These logging techniques, requiring low investments, offer a variety of methods for identifying sweet spots in shale reservoirs, and fracturing only these spots will avoid unnecessary expenditure on frac stages in zones with poor reservoir characteristics.

On the evaluation of steam assisted gravity drainage in naturally fractured oil reservoirs

Full Text Available Steam Assisted Gravity Drainage (SAGD as a successful enhanced oil recovery (EOR process has been applied to extract heavy and extra heavy oils. Huge amount of global heavy oil resources exists in carbonate reservoirs which are mostly naturally fractured reservoirs. Unlike clastic reservoirs, few studies were carried out to determine the performance of SAGD in carbonate reservoirs. Even though SAGD is a highly promising technique, several uncertainties and unanswered questions still exist and they should be clarified for expansion of SAGD methods to world wide applications especially in naturally fractured reservoirs. In this communication, the effects of some operational and reservoir parameters on SAGD processes were investigated in a naturally fractured reservoir with oil wet rock using CMG-STARS thermal simulator. The purpose of this study was to investigate the role of fracture properties including fracture orientation, fracture spacing and fracture permeability on the SAGD performance in naturally fractured reservoirs. Moreover, one operational parameter was also studied; one new well configuration, staggered well pair was evaluated. Results indicated that fracture orientation influences steam expansion and oil production from the horizontal well pairs. It was also found that horizontal fractures have unfavorable effects on oil production, while vertical fractures increase the production rate for the horizontal well. Moreover, an increase in fracture spacing results in more oil production, because in higher fracture spacing model, steam will have more time to diffuse into matrices and heat up the entire reservoir. Furthermore, an increase in fracture permeability results in process enhancement and ultimate recovery improvement. Besides, diagonal change in the location of injection wells (staggered model increases the recovery efficiency in long-term production plan.

Full Text Available INTRODUCTION: Domestic dogs are the most important reservoir in the peridomestic transmission cycle of Leishmania (Leishmania chagasi. The genetic variability of subpopulations of this parasite circulating in dogs has not been thoroughly analyzed in Brazil, even though this knowledge has important implications in the clinical-epidemiological context. METHODS: The objective of this study was to evaluate and compare the phenotypic variability of 153 L. chagasi strains isolated from dogs originating from the municipalities of Rio de Janeiro (n = 57 and Belo Horizonte (n = 96, where the disease is endemic. Strains isolated only from intact skin were selected and analyzed by multilocus enzyme electrophoresis using nine enzyme systems (6PG, GPI, NH1 and NH2, G6P, PGM, MDH, ME, and IDHNADP. RESULTS: The electrophoretic profile was identical for all isolates analyzed and was the same as that of the L. chagasi reference strain (MHOM/BR/74/PP75. Phenetic analysis showed a similarity index of one for all strains, with the isolates sharing 100% of the characteristics analyzed. CONCLUSIONS: The results demonstrate that the L. chagasi populations circulating in dogs from Rio de Janeiro and Belo Horizonte belong to a single zymodeme.

larger than the P-wave velocity. A Modified Discrete Element Approach is introduced because of limitations imposed by the regular DEM. The modified approach works on clusters made of three elements each. Each cluster behaves like a continuum medium before failure and like a DEM medium after failure. The method is tested using several numerical examples. The modified approach is used to model reservoir geomechanical behavior for two North Sea reservoirs. The first model is based on the Gullfaks field, where fracture development during fluid injection is modeled. Two scenarios are modeled, the first scenario shows a possibility of creating vertical fractures and the second shows the possibility of creating horizontal fractures. The directions of the fractures are mainly sensitive to the initial effective stresses of the reservoir. Based on a Gullfaks 4D seismic s cross-section, the horizontal fractures scenario appears to be a more likely possibility. 2D cross-sections from the Elgin-Franklin field are used to model the effects of fault reactivation on the stress field around a depleted reservoir. A 4D seismic s cross-section for the Elgin-Franklin reservoir is used for comparison. The cross-section shows a possibility of using 4D seismic s data to predict fault reactivation based on velocity changes. We can not, at this stage, rule out that the velocity changes shown on the 4D seismic s cross-section correspond to the stress changes around the reactivated fault obtained from the geomechanical model.

Horizontal wells are of increasing interest in the oil and gas industry, as is evident from the increase in the numbers of such wells being drilled. Horizontal well technology is used to improve production rates, notably in low permeability formations; to capture reserves if a reservoir is not economic using non-horizontal wells; to manage breakthrough of sweep fluids and increase sweep efficiency; and to extend the areal reach from a single surface location, especially in offshore production. The types of horizontal wells, differentiated on the basis of how quickly the well becomes horizontal, are briefly outlined and a short history of horizontal wells is presented. Canadian accomplishments in this field are then described, including steerable drilling systems, measurement-while-drilling systems, management of hole drag and torque, and well completion techniques. About 25 horizontal wells are forecast to be drilled in Canada in 1989, indicating the favorable future of this technology. 2 figs., 5 tabs.

The coupled Markov chain model can be used to simulate reservoir lithologies between wells, by conditioning them on the observed data in the cored wells. However, with this method, only the state at the same depth as the current cell is going to be used for conditioning, which may be a problem if the geological layers are dipping. This will cause the simulated lithological layers to be broken or to become discontinuous across the reservoir. In order to address this problem, an actively conditioned process is proposed here, in which a tolerance angle is predefined. The states contained in the region constrained by the tolerance angle will be employed for conditioning in the horizontal chain first, after which a coupling concept with the vertical chain is implemented. In order to use the same horizontal transition matrix for different future states, the tolerance angle has to be small. This allows the method to work in reservoirs without complex structures caused by depositional processes or tectonic deformations. Directional artefacts in the modeling process are avoided through a careful choice of the simulation path. The tolerance angle and dipping direction of the strata can be obtained from a correlation between wells, or from seismic data, which are available in most hydrocarbon reservoirs, either by interpretation or by inversion that can also assist the construction of a horizontal probability matrix.

This annual report describes the progress during the second year of the project on Integrated Approach Towards the Application of Horizontal Wells to Improve Waterflooding Performance. This project is funded under the Department of Energy`s Class I program which is targeted towards improving the reservoir performance of mature oil fields located in fluvial-dominated deltaic deposits. The project involves an integrated approach to characterize the reservoir followed by the drilling of horizontal injection wells to improve production performance. The type of data we have integrated include cross bore hole seismic surveys, geological interpretation based on logs and cores, and engineering information. This report covers the second phase of the project which includes a detailed reservoir description of the field by integrating all the available information, followed by flow simulation of the Self Unit under various operating conditions. Based on an examination of the various operating parameters, we observed that the best possible solution to improve the Self Unit performance is to recomplete and stimulate most of the wells followed by an increase in the water injection rate. Drilling of horizontal injection well, although helpful in improving the performance, was not found to be economically feasible. The proposed reservoir management plan will be implemented shortly.

This paper presented a development plan for an extra-heavy oil field in Venezuela's Orinoco belt involving cold heavy oil production (CHOP) as well as a thermal follow-up process to increase the ultimate recovery factor. A reservoir simulation model was used to model various reservoir formations in order to assess their oil recovery potential. Several thermal recovery processes were considered, such as steam assisted gravity drainage (SAGD), horizontal alternate steam drive (HASD), cyclic steam stimulation (CSS), horizontal continuous steam drive, and combined drive drainage (CDD). A geological static model and dynamic reservoir model were coupled for the well optimization evaluation. Production data were used to identify trends related to specific geological conditions. The study also examined methods of improving slotted liner designs and evaluated the use of electric heating as a means of improving CHOP performance. Results of the study showed that CDD offered the highest recovery rates as a follow-up to CHOP. The CDD process allowed for the use of existing wells drilled in the field. New horizontal wells will be placed between the existing wells. It was concluded that a CDD pilot should be implemented in order to prepare for a commercial implementation plan. 8 refs., 2 tabs., 14 figs.

Full Text Available Since 2006, more than 80 multilateral horizontal wells have been drilled in Panzhuang block, Southern Qinshui Basin. In this paper, 6 typical wells in a region are selected as an example. The thickness of coal, gas content, reservoir pressure, permeability, burial depth, and reservoir pressure conditions are analyzed. The practice shows that production by multilateral horizontal well declines from 43,111 m3/day per well in the 2nd year to 25,126 m3/day per well in the 4th year. The numerical simulation result shows that the lateral interference forms in Well QNP05 after two years of gas production, and the gas content is reduced to less than 8 m3/t within the controlled region after six years. The area of gas content was less than 8 m3/t after eight years of gas production is about 3.2 km2, which is about 76% of the controlled area of the six multilateral horizontal wells. The results indicate that multilateral horizontal wells contribute to high production rates at potentially profitable levels and can also serve as an effective tool for a high-rank CBM field drainage.

In this paper, the feasibility of generating electricity from EGS (enhanced geothermal systems) by oilfield produced water circulating through reservoir stimulated by staged fracturing technology for horizontal wells is investigated based on the geological data of Xujiaweizi area, located in the Daqing Oilfield, northeast China. HDR (hot dry rock) resource potential assessment is carried out by using volumetric method. Reservoir stimulation is numerically simulated based on the geological data of well YS-1 and field fracturing experience in this region. Geometric dimensions and flow conductivity of the resulting fracture are imported into the hydro-thermal model to calculate the electricity generation potential of the proposed EGS power plant. An EGS design scheme is proposed based on the simulation results. The system is also evaluated from the economic and environmental aspects. The results indicate that HDR resource in Xujiaweizi area is of great potential for development. Through the staged fracturing technology for horizontal wells, electricity generation power of the proposed EGS project can roughly meet the commercial standard. For 20 years of continuous production, power generation from the proposed EGS power plant is economic feasible. Meanwhile, significant reductions in greenhouse gas emissions can be achieved. - Highlights: • Staged fracturing technology for horizontal well is used in HDR (hot dry rock) development. • Fracturing simulations and heat production simulations are combined. • A 3 MW power plant is designed in Xujiaweizi based on the simulation results

Accumulation and flow mechanisms in unconventional reservoir are different compared to conventional. This requires a special approach of field management with drilling and stimulation treatments as major factor for further production. Integrated approach of unconventional reservoir production optimization assumes coupling drilling project with full scale reservoir simulation for determine best well placement, well length, fracturing treatment design and mid-length distance between wells. Full scale reservoir simulation model emulate a part of polish shale - gas field. The aim of this paper is to establish influence of technical factor for gas production from shale gas field. Due to low reservoir permeability, stimulation treatment should be direct towards maximizing the hydraulic contact. On the basis of production scenarios, 15 stages hydraulic fracturing allows boost gas production over 1.5 times compared to 8 stages. Due to the possible interference of the wells, it is necessary to determine the distance between the horizontal parts of the wells trajectories. In order to determine the distance between the wells allowing to maximize recovery factor of resources in the stimulated zone, a numerical algorithm based on a dynamic model was developed and implemented. Numerical testing and comparative study show that the most favourable arrangement assumes a minimum allowable distance between the wells. This is related to the volume ratio of the drainage zone to the total volume of the stimulated zone.

Three different school-based sex education and citizenship programs in public schools in Rio de Janeiro, Belo Horizonte, and Salvador, Brazil, were evaluated in a cross-sectional study comparing knowledge, attitudes, and practices in sexuality, citizenship, and gender issues among adolescents participating in the programs' activities as compared to adolescents enrolled in schools without such programs (controls). Results showed that Salvador's program achieved good results, with significant changes in knowledge on sexuality and reproductive physiology, attitudes regarding citizenship, and current use of modern contraceptives; Rio de Janeiro's program succeeded in improving students' knowledge of reproductive physiology and attitudes towards sexuality; Belo Horizonte's participants showed greater knowledge of reproductive physiology and STI/HIV prevention but had less positive attitudes towards gender issues, while reporting greater sexual activity. The main difference between Salvador's program and the others was the focus on creative and cultural activities; Belo Horizonte's main difference was its lack of interaction with health services and professionals. However, after the evaluation Belo Horizonte reframed its educational strategies and launched a scaling-up process in a joint effort with the health and school systems.

This is China`s first case study of high resolution reservoir geological modelling using outcrop information. The key of the modelling process is to build a prototype model and using the model as a geological knowledge bank. Outcrop information used in geological modelling including seven aspects: (1) Determining the reservoir framework pattern by sedimentary depositional system and facies analysis; (2) Horizontal correlation based on the lower and higher stand duration of the paleo-lake level; (3) Determining the model`s direction based on the paleocurrent statistics; (4) Estimating the sandbody communication by photomosaic and profiles; (6) Estimating reservoir properties distribution within sandbody by lithofacies analysis; and (7) Building the reservoir model in sandbody scale by architectural element analysis and 3-D sampling. A high resolution reservoir geological model of Youshashan oil field has been built by using this method.

Effective Stress Law in Unconventional Reservoirs under Different Boundary Conditions

2017-12-01

Unconventional reservoirs have attracted a great deal of research interest worldwide during the past two decades. Low permeability and specialized techniques required to exploit these resources present opportunities for improvement in both production rates and ultimate recovery. Understanding subsurface stress modifications and permeability evolution are valuable when evaluating the prospects of unconventional reservoirs. These reservoir properties are functions of effective stress. As a part of this study, effective stress law, specifically the variation of anisotropic Biot's coefficient under various boundary conditions believed to exist in gas reservoirs by different researchers, has been established. Pressure-dependent-permeability (PdK) experiments were carried out on San Juan coal under different boundary conditions, that is, uniaxial strain condition and constant volume condition. Stress and strain in the vertical and horizontal directions were monitored throughout the experiment. Data collected during the experiments was used to determine the Biot's coefficient in vertical and horizontal directions under these two boundary conditions, treating coal as transversely isotropic. The variation of Biot's coefficient was found to be well correlated with the variation in coal permeability. Based on the estimated values of Biot's coefficients, a theory of variation in its value is presented for other boundary conditions. The findings of the study shed light on the inherent behavior of Biot's coefficient under different reservoir boundary conditions. This knowledge can improve the modeling work requiring estimation of effective stress in reservoirs, such as, pressure-/stress- dependent permeability. At the same time, if the effective stresses are known with more certainty by other methods, it enables assessment of the unknown reservoir boundary conditions.

Effect of heterogeneity in a horizontal well with multiple fractures on the long term forecast in shale gas reservoirs

2011-07-01

Multiple fracture horizontal wells (MFHWs) are the most popular type of method used for exploiting shale gas reservoirs. When analyzing MFHW's a homogeneous completion model is often used, but this rarely occurs in the field. This paper develops a hybrid method for forecasting MFHWs based on a heterogeneous completion and investigates the effect of completion heterogeneity on production forecasts. First, a current forecasting method for homogeneous completions was modified for heterogeneous completions. The new forecasting method was then validated using a numerical simulation. A relationship between Arps' hyperbolic decline exponent and the heterogeneity of a completion for a particular case was then developed. Lastly, a field case was analyzed to compare the impact of forecasting with and without taking a heterogeneous completion into consideration. Through analysis and simulations this paper found that the long-term forecast of MFHWs can be greatly impacted should heterogeneity of the completion be ignored.

Optimum development of a thin box-shaped reservoir with multiply fractured horizontal wells

1998-12-31

An improved definition of the productivity index of multiply fractured wells is proposed, based on the use of Dietz`s shape factors for vertical wells centered in independent box-shaped drainage areas of equal size in a reservoir. Pseudo-radial flow around each fracture is taken into account and pressure drops in the reservoir are accurately estimated. By using the corrected Gringarten mathematical approach, it is confirmed that orthogonal fractures provide much better productivity than a single collinear fracture even at constant material usage. Up to five-fold improvements have been registered when the number of fractures was equal to 1.8 times the reservoir shape ratio (length over width). For best results, the well should be cased and cemented, and hydraulic fractures should be propagated one by one through short perforation clusters. 18 refs., 10 figs., 1 appendix.

The main objectives were: to obtain the petrophysical properties through continuous coring of the oil and water zones; water sampling for the characterization; to verify the effective length of the horizontal well through production logging; to obtain the reservoir productivity and permeability through formation test; to obtain the oil PVT properties through monophasic sampling and to know the lateral variability of the accumulation. New technologies were used as geochemical geosteering, diversionary acidification and chemical tracer production logging. The well test analysis showed permeability and productivity values better than as expected and making possible the development of pilot project in order to evaluate the aquifer behavior, the long term well productivity and performance of the elevation and behavior of the extra-heavy oil offloading for subsequent development of the reservoir.

Crystal Field in Montcalm County, MI, was selected as a field trial site for this project. Analysis of production data for Crystal Field suggests that an additional 200,000 bbls of oil can be produced using one strategically located horizontal well. Total addition production from the Crystal Field could be as much as 6--8 MMBO. Application of the technology developed in this project to other Dundee fields in the area has the potential to increase Dundee production in Michigan by 35%, adding 80--100 MMBO to ultimate recovery. This project will demonstrate through a field trial that horizontal wells can be substantially increase oil production in older reservoirs that are at or near their economic limit. To maximize the potential of the horizontal well and to ensure that a comprehensive evaluation can be made, extensive reservoir characterization will be performed. In addition to the proposed field trial at Crystal Field, 29 additional Dundee fields in a seven-county area have been selected for study in the reservoir characterization portion of this project.

Effect of reservoir characteristics on the response of concrete gravity dams

International Nuclear Information System (INIS)

Baumber, T.; Ghobarah, A.

1992-01-01

In most previous analyses of dam responses to earthquake ground motion, the upstream reservoir is assumed to be infinite in length with horizontal bottom. This is rarely the actual geometry of a reservoir, as the upstream valley typically has complex geometry. A study was carried out to examine the effects of the geometry of the reservoir on the dynamic behavior of the monolith. The dam-foundation-reservoir system is modelled using a sub-structuring approach. The reservoir is modelled using a finite element formulation. The absorptive capacity of the reservoir's foundation is idealized as a one-dimensional boundary condition at the reservoir-foundation interface. The reservoir bottom is assumed to be sloping. It was found that the assumed shape of the upstream reservoir significantly affects the overall response of the dam-foundation-reservoir system. The frequencies and magnitudes of the response peaks are affected by the geometry of the reservoir. It was also found that the value of the wave reflection coefficient at the reservoir bottom has a significant effect on the system's response. 6 refs., 5 figs

For many years, geoscientists and engineers have undertaken research to characterize naturally fractured reservoirs. Geoscientists have focused on understanding the process of fracturing and the subsequent measurement and description of fracture characteristics. Engineers have concentrated on the fluid flow behavior in the fracture-porous media system and the development of models to predict the hydrocarbon production from these complex systems. This research attempts to integrate these two complementary views to develop a quantitative reservoir characterization methodology and flow performance model for naturally fractured reservoirs. The research has focused on estimating naturally fractured reservoir properties from seismic data, predicting fracture characteristics from well logs, and developing a naturally fractured reservoir simulator. It is important to develop techniques that can be applied to estimate the important parameters in predicting the performance of naturally fractured reservoirs. This project proposes a method to relate seismic properties to the elastic compliance and permeability of the reservoir based upon a sugar cube model. In addition, methods are presented to use conventional well logs to estimate localized fracture information for reservoir characterization purposes. The ability to estimate fracture information from conventional well logs is very important in older wells where data are often limited. Finally, a desktop naturally fractured reservoir simulator has been developed for the purpose of predicting the performance of these complex reservoirs. The simulator incorporates vertical and horizontal wellbore models, methods to handle matrix to fracture fluid transfer, and fracture permeability tensors. This research project has developed methods to characterize and study the performance of naturally fractured reservoirs that integrate geoscience and engineering data. This is an important step in developing exploitation strategies for

Practices and prospect of petroleum engineering technologies in ultra-deep sour gas reservoirs, Yuanba Gasfield, Sichuan Basin

Full Text Available Located in the Sichuan Basin, the Yuanba Gasfield is the deepest marine sour gas field among those developed in China so far. Its biohermal gas reservoir of the Upper Permian Changxing Fm is characterized by ultra depth, high content of hydrogen sulfide, medium–low porosity and permeability, and small reservoir thickness. Economic evaluation on it shows that horizontal well drilling is the only way to develop this gas reservoir efficiently and to reduce the total development investment. At present, the petroleum engineering technology for this type of ultra-deep sour gas reservoir is less applied in the world, so an ultra-deep horizontal well is subject to a series of petroleum engineering technology difficulties, such as safe and fast well drilling and completion, mud logging, well logging, downhole operation, safety and environmental protection. Based on the successful development experience of the Puguang Gasfield, therefore, Sinopec Southwest Petroleum Engineering Co., Ltd. took the advantage of integrated engineering geology method to carry out specific technical research and perform practice diligently for 7 years. As a result, 18 key items of technologies for ultra-deep sour gas reservoirs were developed, including horizontal-well drilling speed increasing technology, horizontal-well mud logging and well logging technology, downhole operation technology, and safety and environmental protection technology. These technologies were applied in 40 wells during the first and second phases of productivity construction of the Yuanba Gasfield. All the 40 wells have been built into commercial gas wells, and the productivity construction goal of 3.4 billion m3 purified gas has also been achieved. These petroleum engineering technologies for ultra-deep sour gas fields play a reference role in exploring and developing similar gas reservoirs at home and abroad.

Horizontal drilling has become a routine method of field development over the past several years as a means to maximise recoverable reserves. As such, horizontal drilling has impacted the way that petrophysical data is obtained in order to evaluate the reservoir during and after drilling. In horizontal wells, conventional open hole logging methods must be combined with either pipe conveyed logging techniques or coiled tubing conveyed techniques. In many cases, these procedures are time consuming and cost prohibitive based on the economics of the project. Additionally, formation evaluation data may be obtained in horizontal wells by using Logging While Drilling (LWD) technology, but this may also be cost prohibitive in many areas. In the Girkaliai and Nausodis Fields in Lithuania, two wells were drilled to reach oil producing reservoir sandstones at depths of over 1,800 m TVD with horizontal sections of approximately 270 m and 385 m. Based on an economic and petrophysical analysis, neither open hole pipe conveyed logging nor LSW were considered since neither were regarded as cost effective to obtain the petrophysical data required to evaluate the reservoir. An alternative method to obtain critical formation evaluation data was employed utilizing a cased hole pulsed neutron decay logging tool run in the open hole. In one case this was done immediately after drilling. The pulsed neutron decay logging tool was conveyed to TD by a specially modified wireline tractor system. The obtained logs provided critical information to evaluate the reservoir including determining density porosity, neutron porosity, sigma (formation capture cross section) and gamma ray. The data was used to calculate required petrophysical information including lithology, water saturation, and bulk volumes. (orig.)

The identification of the renin/prorenin receptor, the angiotensin-converting enzyme homologue ACE2 as an angiotensin peptide processing enzyme, Mas as a receptor for Ang-(1-7 and the possibility of signaling through ACE, have contributed to switch our understanding of the RAS from the classical limited-proteolysis linear cascade to a cascade with multiple mediators, multiple receptors, and multi-functional enzymes. In this review we will focus on the recent findings related to RAS and, in particular, on its role in diabetes by discussing possible interactions between RAS mediators, endothelium function, and insulin signaling transduction pathways as well as the putative role of ACE2-Ang-(1-7-Mas axis in disease pathogenesis.Keywords: renin–angiotensin system, diabetes, angiotensin II, angiotensin-(1-7, insulin, endothelium

Seismic response of concrete gravity dams with finite reservoir

Baumber, T.; Ghobarah, A.

1992-01-01

In most previous analyses of dam responses to earthquake ground motion, the upstream reservoir is assumed to be infinite in length and completely straight. The meandering nature of the river system, however, results in the creation of a finite length reservoir upstream of the dam structure. A study was carried out to examine the effects of the finite length of the reservoir on the dynamic behavior of the monolith. The effect of excitation of the far end of the boundary on the monolith's response is also of interest. The dam-foundation-reservoir system is modelled using a sub-structuring approach. The analysis is conducted in the frequency domain and utilizes the finite element technique. The water in the reservoir is assumed to be compressible, inviscid, and irrotational. The upstream reservoir is assumed to have a rectangular cross-section. It was found that the finite length reservoir assumption results in supplementary response peaks in the monolith's response. The finite reservoir length allows the reservoir to resonate both in horizontal and vertical directions. The magnitude and spacing of these supplementary response peaks are dependent on the length of the reservoir. The phase of the ground motion which affects the far end boundary of the reservoir was also found to have a significant effect on the dam monolith's response. 8 refs., 5 figs

Horizontal well drilling with cold production were used to develop most of heavy oil fields in Venezuela's Orinoco heavy oil belt. This study interpreted the horizontal well logs of Block M of the Orinoco heavy oil belt in an effort to improve production from this highly porous and permeable reservoir. The reservoir is comprised primarily of non-consolidated sandstones. A porosity calculation formula for the horizontal well without porosity logs was established based on the study of horizontal well logging data of block M in the Orinoco heavy oil belt. A high quality 3-D simulation tool was used to separate the block into several different sections. A set of methods were presented in order to identify if the well track was approaching an adjacent formation, to estimate the distance between the well track and the adjacent formation, and to correct the deep resistivity of the horizontal section affected by the adjacent formation. A set of interpretation techniques were established, based on the combination of well logging data, seismic data and the oilfield development performance data. It was concluded that the development of the precise 3D geological model helped to establish a solid foundation for guiding the well position design and the drilling of the horizontal well. It also contributed to the reservoir numerical simulation and the effective development of the oil field. 6 refs., 2 tabs., 14 figs.

Most of the reservoirs located in the deep water and ultra-deep water offshore South America are described as unconsolidated sandstone that require sand control on both producers and water injection wells. Horizontal Open Hole Gravel Pack completions are the preferred method of development. If completing heavy oil reservoirs, there is a necessity of longer horizontal open hole sections. Low fracture gradients may limit the length of gravel pack in the open hole section because of the pressure increase during the Beta wave proppant deposition phase. This system allows the gravel pack assembly to be installed and the gravel pack to be pumped during the alpha and beta wave deposition phases without the limitation of high pressures that could fracture the well. The benefits of the Horizontal Single-Trip Gravel Pack and Selective Stimulation System (HSTSSS) using the differential valve include the ability to complete longer horizontal intervals, valuable rig-time savings and, efficient mechanical diversion of the stimulation fluid. This paper outlines the application of the HSTSSS system using a differential valve to complete a horizontal well in offshore deep waters. The need for a differential valve is primarily in horizontal gravel packing operations when normal circulating rates and pressures around the open hole would exceed formation break down pressure. The valve is intended to be easily spaced out and run in the wash pipe. At a predetermined differential pressure the valve opens and the return flow path distance around the bottom of the tailpipe is shortened, thus reducing back pressure preventing filter cake damage without slowing the pump rate. In addition the said valve has to close to allow the selective stimulation to take place. Economic considerations along with completion efficiencies are especially important on deep water, subsea completions. The utilization of differential valves allows completion of extended-reach open hole wells and/or low fracture

A horizontal well can be geologically steered using a forward modelling geosteering software that helps determine the stratigraphic position of the drillstring and interpret the well in the reservoir. The software shows reservoir engineers how to maximize the pay zone, optimize the well path, characterize reservoir properties and avoid entering undesired beds or fluid contacts. The best way to maximize the pay zone is to use an integrated arrangement of formation evaluation tools, software and reservoir engineering expertise. This paper presents a series of measurements while drilling and logging. Drilling (MWD/LWD) tools obtain real-time data and forward modelling while drilling software. When interpreted by a trained specialist, these tools help in decision making processes regarding reservoir depletion. The paper presents a case study from offshore eastern Canada in which a well was drilled horizontally from a semi-submersible mobile drilling unit. StrataSteer {sup TM}, a software tool developed by Halliburton Energy Services, was used to interpret the LWD data. The software is compatible with other downhole tools and the INSITE information system which provides real-time data. The objective of the study is to demonstrate the capabilities of the forward modelling tool while drilling the well. A computer was set up at the client's office and at the offshore rig site. The geological model which was constructed using the acquired data was then used to make real-time collaborative decisions to land the well correctly in the reservoir, maximize the productive interval, optimize the well path, and analyze the reservoir properties. However, it was noted that due to geological uncertainty, the objectives in this well were not achieved. 6 figs.

Seismic analyses and structural evaluations were performed for a cooling water reservoir of a nuclear reactor facility. The horizontal input seismic motion was the NRC Reg. guide 1.60 spectrum shape anchored at 0.20g zero period acceleration. Vertical input was taken as two-thirds of the horizontal input. Soil structure interaction and hydrodynamic effects were addressed in the seismic analyses. Uncertainties in the soil properties were accounted for by considering three soil profiles. Two 2-dimensional SSI models and a 3-dimensional static model. Representing different areas of the reservoir structures were developed and analyzed to obtain seismic forces and moments, and accelerations at various locations. The results included in this paper indicated that both hydrodynamic and soil-structure interaction effects are significant contributors to the seismic responses of the water-retaining walls of the reservoir

The multiscale pore size and specific gas storage mechanism in organic-rich shale gas reservoirs make gas transport in such reservoirs complicated. Therefore, a model that fully incorporates all transport mechanisms and employs an accurate numerical method is urgently needed to simulate the gas production process. In this paper, a unified model of apparent permeability was first developed, which took into account multiple influential factors including slip flow, Knudsen diffusion (KD), surface diffusion, effects of the adsorbed layer, permeability stress sensitivity, and ad-/desorption phenomena. Subsequently, a comprehensive mathematical model, which included the model of apparent permeability, was derived to describe gas production behaviors. Thereafter, on the basis of unstructured perpendicular bisection grids and finite volume method, a fully implicit numerical simulator was developed using Matlab software. The validation and application of the new model were confirmed using a field case reported in the literature. Finally, the impacts of related influencing factors on gas production were analyzed. The results showed that KD resulted in a negligible impact on gas production in the proposed model. The smaller the pore size was, the more obvious the effects of the adsorbed layer on the well production rate would be. Permeability stress sensitivity had a slight effect on well cumulative production in shale gas reservoirs. Adsorbed gas made a major contribution to the later flow period of the well; the greater the adsorbed gas content, the greater the well production rate would be. This paper can improve the understanding of gas production in shale gas reservoirs for petroleum engineers.

Numerical models were used to examine the effect of downhole heaters in enhanced oil recovery (EOR) processes in Venezuela's Orinoco reservoir. The downhole heaters were equipped with mineral-insulated cables that allowed alternating currents to flow between 2 conductors packed in a resistive core composed of polymers and graphite. The heaters were used in conjunction with steam assisted gravity drainage (SAGD) processes and also used in horizontal wells for limited amounts of time in order to accelerate production and pressure declines. The models incorporated the petrophysical and fluid characteristics of the Ayacucho area in the Faja del Orinoco. A compositional-thermal simulator was used to describe heat and fluid flow within the reservoir. A total of 8 scenarios were used to examine the electrical heaters with horizontal and vertical wells with heaters of various capacities. Results of the study were then used in an economic analysis of capitalized and operating costs. Results of the study showed that downhole heaters are an economically feasible EOR option for both vertical and horizontal wells. Use of the heaters prior to SAGD processes accelerated production and achieved higher operational efficiencies. 5 refs., 9 tabs., 15 figs.

In Upper Zakum Field, the interest in horizontal drilling has continued. A second horizontal well was drilled during the second half of 1989. This necessitated running logging tools for well control and to evaluate the reservoir characteristics. The logging tool selected for this well is that of Sperry-Sun. Tools configuration and tolerance were found to fulfil SADCO's requirements and specifications. This paper reports on the services produced which included Measurement While Drilling (MWD) directional services and RLL (Recorded Lithology Logging). The RLL services cover Dual Gamma Ray (DGR), Electromagnetic Wave Resistivity (EWR) and Compensated Neutron Porosity (CN porosity). All the RLL tools were an integrated part of the Bottom Hole Drilling Assembly. Data acquired while surveying was recorded in a recording sub down-hole and retrieved when the tools were up at the surface. A PC assisted quick look interpretation was carried out using Archie's equation in shale free limestone to calculate: Effective porosity, Water Saturation and, Bulk water volume

Problems in the development of high-rank CBM horizontal wells in the Fanzhuang–Zhengzhuang Block in the Qinshui Basin and countermeasures

2017-11-01

Full Text Available Coal reservoirs in the Qinshui Basin are characterized by high thermal evolution degree, low permeability, low reservoir pressure, lower gas saturation and strong heterogeneity, so its coalbed methane (CBM development is quite difficult. In this paper, the development practice of high-rank CBM horizontal wells in the Fanzhuang–Zhengzhuang Block was analyzed in terms of geological and engineering factors to clarify the productivity influencing factors, suitable geological conditions and potential tapping countermeasures of multi-lateral horizontal wells. It is shown that the reasons for the low development efficiency of multi-lateral horizontal wells are divided into three types. The first one is geological factor, such as encountering low CBM content areas or faults. The second is engineering factor, such as drilling fluid plugging, drilling collapse, drainage collapse and dust coal blockage. The third is the combination of both factors. It is concluded that encountering low CBM content areas and faults, collapse and blockage are the main reasons for the low production of multi-lateral horizontal wells in the Zhengzhuang–Fanzhuang Block, with the CBM content higher than 20 m3/t, the ratio of critical desorption pressure and reservoir pressure higher than 0.7 and vitrinite reflectance (Ro higher than 3.8. The prerequisite for an open-hole horizontal well in this area to produce CBM at a high rate is that the well lies in the tensile stress zone. Finally, the countermeasures to tap the potential of some inefficient wells were put forward. First, the inefficient wells which are blocked with dust coal or collapsed in the later stage should be stimulated based on classifications. And second, it is necessary to explore new types of horizontal wells so as to deal with borehole collapse and continue the operation in the later stage by using tree-like roof horizontal wells, single-lateral horizontal wells with casing or screen completion and fish

Numerical Investigation on the Heat Extraction Capacity of Dual Horizontal Wells in Enhanced Geothermal Systems Based on the 3-D THM Model

Full Text Available The Enhanced Geothermal System (EGS constructs an artificial thermal reservoir by hydraulic fracturing to extract heat economically from hot dry rock. As the core element of the EGS heat recovery process, mass and heat transfer of working fluid mainly occurs in fractures. Since the direction of the natural and induced fractures are generally perpendicular to the minimum principal stress in the formation, as an effective stimulation approach, horizontal well production could increase the contact area with the thermal reservoir significantly. In this paper, the thermal reservoir is developed by a dual horizontal well system and treated as a fractured porous medium composed of matrix rock and discrete fracture network. Using the local thermal non-equilibrium theory, a coupled THM mathematical model and an ideal 3D numerical model are established for the EGS heat extraction process. EGS heat extraction capacity is evaluated in the light of thermal recovery lifespan, average outlet temperature, heat production, electricity generation, energy efficiency and thermal recovery rate. The results show that with certain reservoir and production parameters, the heat production, electricity generation and thermal recovery lifespan can achieve the commercial goal of the dual horizontal well system, but the energy efficiency and overall thermal recovery rate are still at low levels. At last, this paper puts forward a series of optimizations to improve the heat extraction capacity, including production conditions and thermal reservoir construction design.

IMPROVED MISCIBLE NITROGEN FLOOD PERFORMANCE UTILIZING ADVANCED RESERVOIR CHARACTERIZATION AND HORIZONTAL LATERALS IN A CLASS I RESERVOIR - EAST BINGER (MARCHAND) UNIT

Budget Period 2 of the East Binger Unit (''EBU'') DOE Project has been. Recent activities included additional data gathering and project monitoring, plus initiation of work on an SPE paper on the modeling efforts of the project. Early production performance suggests horizontal wells do not provide sufficient additional production over vertical wells to justify their incremental cost. It will take more time to evaluate the impact of the horizontal wells on sweep and ultimate recovery, but it is unlikely that an improvement in recovery will be sufficient to make the overall economic value of horizontal wells greater than the economic value of vertical wells. Monitoring of overall performance of the pilot area continues. Overall response to the various projects continues to be very favorable. Injection into the pilot area has nearly doubled, while gas production and nitrogen content of produced gas have both decreased. Nitrogen recycle within the pilot area has dropped from 60% to 20%. Efforts to further disseminate knowledge gained through this project, by means of technical paper presentations to industry groups, are underway. Project monitoring and technology transfer will be focus areas of Budget Period 3

Principal permeability determination from multiple horizontal well tests

A method for obtaining principal permeability magnitudes and direction that requires only the linear flow regime from transient tests in three horizontal wells oriented in three distinct and arbitrary directions, is described. Well design optimization strategies require knowledge of both the principal permeability orientation as well as the horizontal permeability magnitudes. When the degree of horizontal permeability anisotropy (i.e. permeability in the bedding plane with respect to direction) is significant, the productivity of a long horizontal well will depend greatly on its direction, especially when the well is first brought into production. Productivities have been found to deviate substantially among wells in the same reservoir and this deviation has been attributed to differences in well orientation. In view of this fact, measuring permeability anisotropy becomes a compelling necessity. The success of the proposed method is illustrated by a case study in which the principal permeability magnitudes and direction from three wells were used to predict the productivity of a fourth well within 10 per cent.

fields with very heterogeneous permeability, such as karstic reservoirs, a horizontal well has a very good chance of encountering highly productive zones (case of Rospo Mare in Italy where a productivity increase of 10 and more was found in comparison with neighboring vertical wells. A study of overall productivity on the scale of the field confirms that, if vertical wells are to be replaced by horizontal wells, their number may be divided by a factor of about 4 to obtain the sa:e production under equivalent conditions. To prevent water (or gas influxes during multiphase flow, a horizontal well has two advantages. It can be drilled near the top of the reservoir so as to obtain as much clearance as possible. Likewise, even with greater total production, production per unit length is less, thus locally causing more moderate stress on the oil/water or oil/gas interface. The shape of this interface is thus smoother, and calculations show that vertical sweep is more efficient, and hence recovery is greater. Generally speaking, in multiphase flow, horizontal wells reveal all the more superiority as the mobility ratio is unfavorable, e. g. heavy oil driven by water. The phenomenon to be prevented is indeed the breakthrough of fronts, which occurs all the sonner as flow is more unstable. The steadiness of drainage among horizontal wells provides more homogeneous progression to fronts, which is especially advantageous at the beginning of production. Nonetheless, since reservoirs are more or less heterogeneous, full benefit can be drawn from such favorable effects only if selective completions can be implemented in horizontal wells. For partly similar reasons, horizontal wells are advantageous for thermal recovery. The exact positioning of a perforated injection casing at a specific depth in a reservoir should enable steam to be fed in easily so that the zone it invades expands steadily, while decreasing heat losses into the surrounding formations. Lastly, it should be added that

Three types of gas hydrate reservoirs in the Gulf of Mexico identified in LWD data

2011-01-01

High quality logging-while-drilling (LWD) well logs were acquired in seven wells drilled during the Gulf of Mexico Gas Hydrate Joint Industry Project Leg II in the spring of 2009. These data help to identify three distinct types of gas hydrate reservoirs: isotropic reservoirs in sands, vertical fractured reservoirs in shale, and horizontally layered reservoirs in silty shale. In general, most gas hydratebearing sand reservoirs exhibit isotropic elastic velocities and formation resistivities, and gas hydrate saturations estimated from the P-wave velocity agree well with those from the resistivity. However, in highly gas hydrate-saturated sands, resistivity-derived gas hydrate-saturation estimates appear to be systematically higher by about 5% over those estimated by P-wave velocity, possibly because of the uncertainty associated with the consolidation state of gas hydrate-bearing sands. Small quantities of gas hydrate were observed in vertical fractures in shale. These occurrences are characterized by high formation resistivities with P-wave velocities close to those of water-saturated sediment. Because the formation factor varies significantly with respect to the gas hydrate saturation for vertical fractures at low saturations, an isotropic analysis of formation factor highly overestimates the gas hydrate saturation. Small quantities of gas hydrate in horizontal layers in shale are characterized by moderate increase in P-wave velocities and formation resistivities and either measurement can be used to estimate gas hydrate saturations.

Reservoir characterization of the Mt. Simon Sandstone, Illinois Basin, USA

The integration of open hole well log analyses, core analyses and pressure transient analyses was used for reservoir characterization of the Mt. Simon sandstone. Characterization of the injection interval provides the basis for a geologic model to support the baseline MVA model, specify pressure design requirements of surface equipment, develop completion strategies, estimate injection rates, and project the CO2 plume distribution.The Cambrian-age Mt. Simon Sandstone overlies the Precambrian granite basement of the Illinois Basin. The Mt. Simon is relatively thick formation exceeding 800 meters in some areas of the Illinois Basin. In the deeper part of the basin where sequestration is likely to occur at depths exceeding 1000 m, horizontal core permeability ranges from less than 1 ?? 10-12 cm 2 to greater than 1 ?? 10-8 cm2. Well log and core porosity can be up to 30% in the basal Mt. Simon reservoir. For modeling purposes, reservoir characterization includes absolute horizontal and vertical permeability, effective porosity, net and gross thickness, and depth. For horizontal permeability, log porosity was correlated with core. The core porosity-permeability correlation was improved by using grain size as an indication of pore throat size. After numerous attempts to identify an appropriate log signature, the calculated cementation exponent from Archie's porosity and resistivity relationships was used to identify which porosity-permeability correlation to apply and a permeability log was made. Due to the relatively large thickness of the Mt. Simon, vertical permeability is an important attribute to understand the distribution of CO2 when the injection interval is in the lower part of the unit. Only core analyses and specifically designed pressure transient tests can yield vertical permeability. Many reservoir flow models show that 500-800 m from the injection well most of the CO2 migrates upward depending on the magnitude of the vertical permeability and CO2 injection

A proposta foi investigar se diferenciais socioeconômicos (especificamente renda e educação e demográficos (especificamente estrutura etária e domiciliar são importantes na definição do volume de resíduos gerado em sub-regiões do município. O consumo, nesse sentido, é visto como o elo entre as dimensões "população" e "geração de resíduos". A fonte de dados sobre a geração de resíduos sólidos é a Superintendência de Limpeza Urbana (SLU, responsável pela coleta e sistematização das informações em uma malha cartográfica digital. Tal representação espacial das informações permitiu concatená-las com os dados da malha digital das Áreas de Ponderação do Instituto Brasileiro de Geografia e Estatística (IBGE, referentes ao Censo Demográfico 2000. Métodos estatísticos multivariados foram empregados para investigar as associações entre variáveis populacionais e a produção de resíduos.

Evaluation of the two formation characteristics conducive to economic well production is important when tight shale formation characterization and completion design are being considered. This paper presents the basic understanding required to improve the efficiency of horizontal completions in oil and gas producing shales. Guidelines are defined for effective perforation and fracturing to improve the efficiency and sustainability of horizontal completions using extensive laboratory characterization of mechanical properties on core, core/log integration and continuous mapping of these properties by logging-while-drilling (LWD) methods. The objective is to improve completion design efficiency. This is accomplished by suitable selection of perforation intervals based on an understanding of the relevant physical processes and rock characterization. Conditions at two reservoir regions, the near-wellbore and the far-wellbore, are outlined and are essential to completion design. From the study, it can be concluded that tight shales are strongly anisotropic and cannot be approximated using isotropic models.

Field results from a number of scale squeeze treatments carried out on subsea and platform horizontal wells in the Nelson Field of the North Sea are presented. Scale inhibitor chemicals are reviewed along with factors which influence inhibitor selection for both horizontal and highly deviated wells. Formation brine/inhibitor incompatibility, formation minerals/inhibitor incompatibility, and the potential for sand production and oil-in-water process as a result of these incompatibilities, are discussed. Practical difficulties in squeezing subsea horizontal wells, the use of chemical stabilizers to reduce formation brine/inhibitor incompatibility, variation of pump rates to encourage propagation of inhibitor along the wellbore, and the potential of fluid diversion are outlined, stressing the significance of production logging data (or good reservoir simulation data), to evaluate the location of water production prior to the squeeze treatment. Results of these treatments show that with the correct laboratory evaluation of both scale inhibitor and divertor agents, and with appropriate utilization of production logging or reservoir simulation data, it is possible to carry out scale inhibitor squeeze treatments of subsea and platform horizontal wells without having to resort to coiled tubing. 22 refs., 1 tab., 14 figs

Feasibility study on application of volume acid fracturing technology to tight gas carbonate reservoir development

Full Text Available How to effectively develop tight-gas carbonate reservoir and achieve high recovery is always a problem for the oil and gas industry. To solve this problem, domestic petroleum engineers use the combination of the successful experiences of North American shale gas pools development by stimulated reservoir volume (SRV fracturing with the research achievements of Chinese tight gas development by acid fracturing to propose volume acid fracturing technology for fractured tight-gas carbonate reservoir, which has achieved a good stimulation effect in the pilot tests. To determine what reservoir conditions are suitable to carry out volume acid fracturing, this paper firstly introduces volume acid fracturing technology by giving the stimulation mechanism and technical ideas, and initially analyzes the feasibility by the comparison of reservoir characteristics of shale gas with tight-gas carbonate. Then, this paper analyzes the validity and limitation of the volume acid fracturing technology via the analyses of control conditions for volume acid fracturing in reservoir fracturing performance, natural fracture, horizontal principal stress difference, orientation of in-situ stress and natural fracture, and gives the solution for the limitation. The study results show that the volume acid fracturing process can be used to greatly improve the flow environment of tight-gas carbonate reservoir and increase production; the incremental or stimulation response is closely related with reservoir fracturing performance, the degree of development of natural fracture, the small intersection angle between hydraulic fracture and natural fracture, the large horizontal principal stress difference is easy to form a narrow fracture zone, and it is disadvantageous to create fracture network, but the degradable fiber diversion technology may largely weaken the disadvantage. The practices indicate that the application of volume acid fracturing process to the tight-gas carbonate

Full Text Available O Brasil ocupou o oitavo lugar em números absolutos de suicídios no mundo em 2012. Apesar do suicídio com arma de fogo (AF não ser a modalidade mais comum, é frequente seu encontro na prática pericial criminal. Na maioria dos suicídios com AF há apenas um disparo efetivo e o encontro de duas ou mais lesões de entrada classifica o suicídio como atípico. Neste estudo foram avaliados os suicídios atípicos com dois ou mais disparos efetivos de AF nas necropsias do Instituto Médico Legal de Belo Horizonte realizadas entre 2006 e 2012. Foram resgatados cinco casos, correspondendo a 2,63% do total de suicídios com AF autopsiados no período estudado. A maioria dos casos era do sexo masculino, solteira, tinha pele morena, apresentava idade média de 42,3 anos e recebeu atendimento médico previamente ao óbito. Em quatro casos foram observadas duas lesões de entrada de projéteis de AF e em apenas um foram observadas três. Todos apresentavam lesões de entrada no tórax, a maioria localizada na região peitoral esquerda. Em dois indivíduos houve lesões de entrada no tórax e na cabeça. A causa da morte da maioria foi traumatismo torácico perfuro-contuso. Apesar da necropsia forense ser crucial no estabelecimento da causa médica da morte e na avaliação da capacidade de desempenhar atos motores voluntários após um primeiro disparo, a investigação criminal de casos de suicídios atípicos é um trabalho multidisciplinar, onde cada uma das peças periciais deve se encaixar adequadamente para o estabelecimento correto da causa jurídica da morte.

Full Text Available The Yuanba Gasfield is a large gas field discovered by Sinopec in the Sichuan Basin in recent years, and another main exploration area for natural gas reserves and production increase after the Puguang Gasfield. The ultra-deep sour gas reservoir in the Yuanba Gasfield is characterized by complicated geologic structure, deep reservoirs and complex drilled formation, especially in the continental deep strata which are highly abrasive with low ROP (rate of penetration and long drilling period. After many years of drilling practice and technical research, the following six key drilling and completion technologies for this type reservoir are established by introducing new tools and technologies, developing specialized drill bits and optimizing drilling design. They are: casing program optimization technology for ROP increasing and safe well completion; gas drilling technology for shallow continental strata and high-efficiency drilling technology for deep high-abrasion continental strata; drilling fluid support technologies of gas–liquid conversion, ultra-deep highly-deviated wells and horizontal-well lubrication and drag reduction, hole stability control and sour gas contamination prevention; well cementing technologies for gas medium, deep-well long cementing intervals and ultra-high pressure small space; horizontal-well trajectory control technologies for measuring instrument, downhole motor optimization and bottom hole assembly design; and liner completion modes and completion string optimization technologies suitable for this gas reservoir. Field application shows that these key technologies are contributive to ROP increase and efficiency improvement of 7000 m deep horizontal wells and to significant operational cycle shortening.

Generation of hybrid meshes for the simulation of petroleum reservoirs; Generation de maillages hybrides pour la simulation de reservoirs petroliers

Energy Technology Data Exchange (ETDEWEB)

Balaven-Clermidy, S.

2001-12-01

Oil reservoir simulations study multiphase flows in porous media. These flows are described and evaluated through numerical schemes on a discretization of the reservoir domain. In this thesis, we were interested in this spatial discretization and a new kind of hybrid mesh has been proposed where the radial nature of flows in the vicinity of wells is directly taken into account in the geometry. Our modular approach described wells and their drainage area through radial circular meshes. These well meshes are inserted in a structured reservoir mesh (a Corner Point Geometry mesh) made up with hexahedral cells. Finally, in order to generate a global conforming mesh, proper connections are realized between the different kinds of meshes through unstructured transition ones. To compute these transition meshes that we want acceptable in terms of finite volume methods, an automatic method based on power diagrams has been developed. Our approach can deal with a homogeneous anisotropic medium and allows the user to insert vertical or horizontal wells as well as secondary faults in the reservoir mesh. Our work has been implemented, tested and validated in 2D and 2D1/2. It can also be extended in 3D when the geometrical constraints are simplicial ones: points, segments and triangles. (author)

Engineering (both at The University of Texas at Austin) to define the controls on fluid flow in the reservoir as a basis for developing a reservoir model. The successful development of HPAI technology has tremendous potential for increasing the flow of oil from deep carbonate reservoirs in the Permian Basin, a target resource that can be conservatively estimated at more than 1.5 billion barrels. Successful implementation in the field chosen for demonstration, for example, could result in the recovery of more than 34 million barrels of oil that will not otherwise be produced. Geological and petrophysical analysis of available data at Barnhart field reveals the following important observations: (1) the Barnhart Ellenburger reservoir is similar to most other Ellenburger reservoirs in terms of depositional facies, diagenesis, and petrophysical attributes; (2) the reservoir is characterized by low to moderate matrix porosity much like most other Ellenburger reservoirs in the Permian Basin; (3) karst processes (cave formation, infill, and collapse) have substantially altered stratigraphic architecture and reservoir properties; (4) porosity and permeability increase with depth and may be associated with the degree of karst-related diagenesis; (5) tectonic fractures overprint the reservoir, improving overall connectivity; (6) oil-saturation profiles show that the oil-water contact (OWC) is as much as 125 ft lower than previous estimations; (7) production history and trends suggest that this reservoir is very similar to other solution-gas-drive reservoirs in the Permian Basin; and (8) reservoir simulation study showed that the Barnhart reservoir is a good candidate for HPAI and that application of horizontal-well technology can improve ultimate resource recovery from the reservoir.

Full Text Available It is difficult to forecast the well productivity because of the complexity of vertical and horizontal developments in fluvial facies reservoir. This paper proposes a method based on Principal Component Analysis and Artificial Neural Network to predict well productivity of fluvial facies reservoir. The method summarizes the statistical reservoir factors and engineering factors that affect the well productivity, extracts information by applying the principal component analysis method and approximates arbitrary functions of the neural network to realize an accurate and efficient prediction on the fluvial facies reservoir well productivity. This method provides an effective way for forecasting the productivity of fluvial facies reservoir which is affected by multi-factors and complex mechanism. The study result shows that this method is a practical, effective, accurate and indirect productivity forecast method and is suitable for field application.

1992-01-01

This paper reports that simulation models of the Prudhoe Bay Northwest Fault Block (NWFB) waterflood project, with core-plug-derived permeabilities, predicted that injected water would slump because of gravity segregation. Detailed analysis of surveillance logs and production data for one pattern identified tritium tracer breakthrough in surrounding producers without significant slumping. To duplicate the nearly horizontal movement of injected water, a k V /k H ratio that is an order of magnitude lower than previously modeled is required. This improved reservoir characterization led to revision of the reservoir management strategy for the NWFB

2017-09-01

Full Text Available Oil production from the Viking play in Saskatchewan province started in the 1950s and continues since that time. Horizontal drilling and multistage fracturing have caused resurgence in development of this play. Based on the production data from several fields, the comparative results of the Viking play development using vertical and horizontal wells are presented. Horizontal wells drilling made it possible to increase oil production in those formation zones that were previously considered predominantly gas-saturated, as well as in the zones affected by water injection using vertical wells in order to maintain reservoir pressure. Infill drilling combined with longer lateral completion length also positively affected the development of oil reserves from the Viking play.

Sleeving-back of horizontal wells to control downstream oil saturation and improve oil recovery

Greaves, M.; Saghr, A. M. [Bath Univ (United Kingdom)

Air injection has become popular as an enhanced recovery technology, applicable over a wide variety of reservoir conditions including heavy, medium and light oils. One problem observed in light oil reservoirs is the tendency to desaturate the oil layer downstream of the moving front. This is particularly common in the case of thermal recovery processes. In this experiment designed to study ways to restrict the de-saturation of the oil layer, a modified horizontal producer well, incorporating a `sleeve-back` principal was used. The objective was to replicate the `toe-to-heel` displacement process occurring during heavy oil recovery, wherein downstream oil is essentially immobile due to its high viscosity. The `sleeve-back` of the well was achieved using a co-aligned, two-well assembly, so that the upstream section of the horizontal producer well was active, and continuously adjusted during propagation of the combustion front. The use of this continuous `sleeve-back` operation to control the level of de-saturation in the downstream section of a sand pack was successful as confirmed by the very high oil recovery achieved, equivalent to 93.5 per cent of oil in place. The level of CO{sub 2} production was also very high. The `sleeve-back` of the horizontal producer well made the light oil in-situ combustion more efficient compared to what would be expected in a fully-open well. The `sleeve-back` of the well also produced thermal contours in the sand pack that closely resembled those observed with heavy, highly viscous oil. By sealing-off the otherwise open well in the downstream part of the reservoir, the de-saturation of the oil layer was prevented. 9 refs., 4 tabs., 9 figs.

Significant emphasis has been placed on developing cost-effective strategies for the production of large heavy oil and bitumen reserves located in western Canada and around the world. An effective method that has been proven to be effective in this regard is steam-assisted gravity drainage (SAGD). However, determining the optimum and cost-effective strategy is a challenge to any SAGD reservoir. Average rock quality and reservoir heterogeneities have a significant impact on steam chamber development and the overall volumetric sweep. As well, the approach to SAGD simulation varies as heterogeneity changes. This paper examined two well pairs with different degrees of heterogeneity in the Surmont pilot project. The paper also addressed potential geological risk through analogy and the amount of heterogeneity that must be accounted for when developing a representative simulation. The paper provided background information on the Surmont pilot project, which consists of three horizontal SAGD well pairs in the Athabasca oil sands of northeast Alberta. The reservoir simulation model was then described. Results and conclusions were offered. It was concluded that careful production controls and strategy must be applied particular to the reservoir to ensure that the SAGD well pairs were capable of draining the mobilized oil. 5 refs., 1 tab., 25 figs.

The technologies that were available in the past to improve reservoir performance include 3-D seismic, coiled tubing, horizontal wells, and PCP's. Future enabling technologies will also include multi-lateral wells, 'smart' wells, underbalanced drilling, and downhole fluids processing. A description of 'smart' well technology was given, defined as well completions which facilitate downhole monitoring and control of production to achieve maximum reserves recovery. The current development for 'smart' wells is focused on offshore and subsea wells for marginal field development and work-over mitigation, with the emphasis in system design for production control of horizontal and multi-lateral wells. Basic 'smart' well configuration, instrumentation and monitoring systems, applications of 'smart' well technology in the Western Canadian Sedimentary Basin, and future developments and applications for the technology in general, were also discussed. 30 figs

An optimal design of cluster spacing intervals for staged fracturing in horizontal shale gas wells based on the optimal SRVs

Directory of Open Access Journals (Sweden)

Lan Ren

2017-09-01

Full Text Available When horizontal well staged cluster fracturing is applied in shale gas reservoirs, the cluster spacing is essential to fracturing performance. If the cluster spacing is too small, the stimulated area between major fractures will be overlapped, and the efficiency of fracturing stimulation will be decreased. If the cluster spacing is too large, the area between major fractures cannot be stimulated completely and reservoir recovery extent will be adversely impacted. At present, cluster spacing design is mainly based on the static model with the potential reservoir stimulation area as the target, and there is no cluster spacing design method in accordance with the actual fracturing process and targets dynamic stimulated reservoir volume (SRV. In this paper, a dynamic SRV calculation model for cluster fracture propagation was established by analyzing the coupling mechanisms among fracture propagation, fracturing fluid loss and stress. Then, the cluster spacing was optimized to reach the target of the optimal SRVs. This model was applied for validation on site in the Jiaoshiba shale gasfield in the Fuling area of the Sichuan Basin. The key geological engineering parameters influencing the optimal cluster spacing intervals were analyzed. The reference charts for the optimal cluster spacing design were prepared based on the geological characteristics of south and north blocks in the Jiaoshiba shale gasfield. It is concluded that the cluster spacing optimal design method proposed in this paper is of great significance in overcoming the blindness in current cluster perforation design and guiding the optimal design of volume fracturing in shale gas reservoirs.

Maloney, D.; Doggett, K.

1997-08-01

X-ray techniques are used in petroleum laboratories for a variety of reservoir characterization measurements. This paper describes the configuration of a 2D X-ray scanner and many of the ways in which it simplifies and improves accuracy`s of laboratory measurements. Linear X-ray scanners are most often used to provide descriptions of fluid saturations within core plugs during flow tests. We configured our linear scanner for both horizontal and vertical movement. Samples can be scanned horizontally, vertically, or according to horizontal and vertical grids. X-ray measurements are fast, allowing measurements of two- and three-phase fluid saturations during both steady- and unsteady-state flow processes. Rock samples can be scanned while they are subjected to stress, pore pressure, and temperature conditions simulating those of a petroleum reservoir. Many types of measurements are possible by selecting appropriate X-ray power settings, dopes, filters, and collimator configurations. The scanner has been used for a variety of applications besides fluid saturation measurements. It is useful for measuring porosity distributions in rocks, concentrations of X-ray dopes within flow streams during tracer tests, gap widths in fracture flow cells, fluid interface levels in PVT cells and fluid separators, and other features and phenomena.

Electro-magnetic heating in viscous oil reservoir

This paper discussed electromagnetic (EM) heating techniques for primary and secondary enhanced oil recovery (EOR) processes. Ohmic, induction, and formation resistive heating techniques were discussed. Issues related to energy equivalence and hardware requirements were reviewed. Challenges related to heat losses in vertical wellbores, well integrity, and galvanic corrosion were also outlined. A pair of 1500 foot horizontal wells in a heavy oil reservoir were then modelled in order to optimize EM recovery processes. DC current was used in a base case water flood run. Electrical conductivities were measured. The model was converted to a homogenous model in order to study injector and producer electrodes. The study showed that reservoir resistance was low, and most of the heating took place near the electrode area where electric lines diverged or converged. Results of the study suggested that EM heating in formations is not as efficient as steam-based processes. Accurate simulations of EM heating processes within reservoirs are difficult to obtain, as the amounts of estimated heat input are sensitive to grid refinement. It was concluded that hot spots in the EM electrodes have also caused failures in other field applications and studies. 11 refs., 12 figs.

Chemical placement in heterogeneous and long reach horizontal wells

The effective placement of chemical squeeze treatments in heterogeneous wells and long reach horizontal wells has proved a significant challenge, with various factors including heterogeneity, crossflow and pressure gradients between otherwise non-communicating zones within the well, all contributing to an uneven placement of the scale squeeze treatment into the reservoir. Current methods to circumvent these problems often rely on extremely expensive coiled tubing operations, staged diversion (temporary shut off) treatments or by designing treatments to deliberately overdose some zones in order to gain placement in other (e.g. low permeability) zones. Moreover for deepwater sub sea horizontal wells the costs associated with ''spot'' treating along the length of horizontal wells by coil tubing tractor operations can often be prohibitively expensive. For other very near well bore treatments such as acid stimulation a number of self diverting strategies including gelled acid treatments, staged viscoelastic surfactant treatments and foams have been applied in field treatments with some success. However the properties which make such treatments applicable for acid stimulation may also make them inappropriate for bullhead scale squeeze treatments. Recent work by the current authors has however indicated the possible benefits of using modified injection fluids to aid uniform scale inhibitor placement in such wells in order to effect more even placement. In summary this paper will describe the various options available for achieving self diversion and describes the potential drawbacks associated with the viscous placement fluids commonly used for acid simulation techniques. In addition, various simulation packages commonly used for scale related calculations are reviewed and their limitations, primarily due to the inherent assumptions made and input parameters used, for modelling squeeze treatments using such modified fluids are described.

Horizontal Gene Transfers in Mycoplasmas (Mollicutes).

2018-04-12

The class Mollicutes (trivial name "mycoplasma") is composed of wall-less bacteria with reduced genomes whose evolution was long thought to be only driven by gene losses. Recent evidences of massive horizontal gene transfer (HGT) within and across species provided a new frame to understand the successful adaptation of these minimal bacteria to a broad range of hosts. Mobile genetic elements are being identified in a growing number of mycoplasma species, but integrative and conjugative elements (ICEs) are emerging as pivotal in HGT. While sharing common traits with other bacterial ICEs, such as their chromosomal integration and the use of a type IV secretion system to mediate horizontal dissemination, mycoplasma ICEs (MICEs) revealed unique features: their chromosomal integration is totally random and driven by a DDE recombinase related to the Mutator-like superfamily. Mycoplasma conjugation is not restricted to ICE transmission, but also involves the transfer of large chromosomal fragments that generates progenies with mosaic genomes, nearly every position of chromosome being mobile. Mycoplasmas have thus developed efficient ways to gain access to a considerable reservoir of genetic resources distributed among a vast number of species expanding the concept of minimal cell to the broader context of flowing information.

An experimental horizontal well using limited-entry perforations as a method for distributing steam to different zones was used to replace ten vertical injection wells. The well was located between rows of vertical wells in a reservoir that has been subjected to more than ten years of operation under cyclic steam stimulation. The limited-entry perforations enabled steam to be targeted at the cold regions of the reservoir. This paper presents an assessment of the well based on theoretical calculations, measured injection pressures and rates and 3-D seismic imaging. All the data collected during the experiment support the conclusion that effective steam distribution along the well has been achieved. It was also concluded that this technology has significant potential for SAGD applications as a mechanism for achieving improved steam distribution at a much reduced cost. 5 refs., 8 figs.

Improving steamflood effectiveness by horizontal producers

The Emlichheim oilfield is located in North-West-Germany on the Dutch-German border being the Southern downdip part of the Schoonebeek anticline. The field was discovered in 1943 and came on production in 1944. Since production startup, Wintershall operates the field as owner of the concession (90% share of interest) in a joint venture with Mobil Erdgas-Erdoel GmbH (10%). For more than 50 years an average crude oil production of 150.000 t/year has been maintained. Starting with huff ''n'' puff and hot water flooding in the late 60's, the first steam flood project was implemented in 1981. Further steamflood projects started in 1989, 1992, 1993, 1994 and 1998 in different areas of the field. Until 1997, only vertical production wells were drilled in the field. Wellbore stability seemed to be a major problem for drilling horizontal wells in the unconsolidated sandstone reservoir at that time. In 1999 an innovative steamflood project was started with three newly drilled horizontal producers surrounding a vertical steam injector. First results are showing a significant improvement in the performance as compared to the earlier projects and offer new chances for further development of the field. Today, the field could no longer be operated without the steam projects as roughly 95% of the field production is coming from thermal EOR. This paper gives a brief overview of the field and its production history, the planning and realization of a current steamflood project using horizontal well technology as well as its performance compared to the earlier projects. It also describes the experience of drilling horizontal wells in the unconsolidated sandstone. A brief outlook to the future field development is given. (orig.)

Research described In this report addresses the internal architecture of two specific reservoir types: restricted-platform carbonates and fluvial-deltaic sandstones. Together, these two reservoir types contain more than two-thirds of the unrecovered mobile oil remaining ill Texas. The approach followed in this study was to develop a strong understanding of the styles of heterogeneity of these reservoir types based on a detailed outcrop description and a translation of these findings into optimized recovery strategies in select subsurface analogs. Research targeted Grayburg Formation restricted-platform carbonate outcrops along the Algerita Escarpment and In Stone Canyon In southeastern New Mexico and Ferron deltaic sandstones in central Utah as analogs for the North Foster (Grayburg) and Lake Creek (Wilcox) units, respectively. In both settings, sequence-stratigraphic style profoundly influenced between-well architectural fabric and permeability structure. It is concluded that reservoirs of different depositional origins can therefore be categorized Into a heterogeneity matrix'' based on varying intensity of vertical and lateral heterogeneity. The utility of the matrix is that it allows prediction of the nature and location of remaining mobile oil. Highly stratified reservoirs such as the Grayburg, for example, will contain a large proportion of vertically bypassed oil; thus, an appropriate recovery strategy will be waterflood optimization and profile modification. Laterally heterogeneous reservoirs such as deltaic distributary systems would benefit from targeted infill drilling (possibly with horizontal wells) and improved areal sweep efficiency. Potential for advanced recovery of remaining mobile oil through heterogeneity-based advanced secondary recovery strategies In Texas is projected to be an Incremental 16 Bbbl. In the Lower 48 States this target may be as much as 45 Bbbl at low to moderate oil prices over the near- to mid-term.

No Brasil, por muitos anos, a atribuição de planejamento em saneamento básico ficou relegada aos prestadores dos serviços. Durante a vigência do Plano Nacional de Saneamento (1971 – 1986 uma das características mais marcantes foi a omissão do Poder Público municipal e a falta de participação dos usuários dos serviços no processo de planejamento das ações em saneamento básico. O País passou um período longo sem um arcabouço institucional e legal que orientasse as atividades relacionadas aos serviços públicos de saneamento básico. O novo marco legal do saneamento básico avança no sentido de colocar a ação de planejamento como estratégica na gestão dos serviços. Segundo a Lei nº 11.445/2007, o planejamento é uma atividade do titular dos serviços, o município, e indelegável a outro ente. A Lei também inaugura uma nova fase da área ao eleger como um dos seus princípios fundamentais o controle social, garantindo à sociedade o acesso a informações e a participação nos processos de formulação de políticas, de planejamento e de avaliação dos serviços.

Full Text Available This study evaluated the acute toxicity of sediment in a eutrophic reservoir after remediation with a calcium nitrate solution to retain phosphorus. The study involved microcosms of surface sediments and water from the sediment-water interface in the Ibirité reservoir. This reservoir, located in the vicinity of metropolitan Belo Horizonte (Minas Gerais, SE Brazil, is a water body that receives treated effluents from an oil refinery (REGAP-Petrobras, as well as high loads of untreated urban effluents from the city of Ibirité and surrounding areas and industrial effluents from a major industrial park. Incubation times of the treatment experiments were: t = 0, t = 5, t = 10, t = 25, t = 50, t = 85 and t = 135 days. One control microcosm and three treated microcosms were analysed in each time interval. Acute toxicity of water samples was assessed with Ceriodaphnia silvestrii Daday, 1902 and that of bulk sediment samples with Chironomus xanthus Rempel, 1939. Toxicity tests were carried out concomitantly with chemical analyses of dissolved inorganic nitrogen species (ammonia, nitrate and nitrite, sulfate and metals in the water samples of the microcosms. Acid volatile sulfides (AVS, simultaneously extracted metal (SEM and potentially bioavailable metal were analyzed in bulk sediment samples. Neither of the tested organisms showed toxicity in the control microcosm samples. The water column of the treated microcosm showed toxicity to C. silvestrii, starting at t = 10 days, while the sediment pore water toxicity started at t = 0 day. However, toxicity was found to decline from t = 85 days to t = 135 days. Sediments showed toxicity to C. xanthus during the entire experiment, except at the longest incubation time (t = 135 days. The overall results indicate that nitrate, which reached concentrations exceeding 1,200 mg N-NO3- L-1 in the sediment pore water of the treated microcosms, was most probably responsible for the toxicity of the samples.

Horizontal wells are commonly used in Saudi Arabia because they have proven advantages in optimizing production and cost. However, in order to ensure proper production, these wells occasionally require downhole measurements of the flow profile; wellbore parameters such as water entry points; and productivity index for remedial action, such as water shut off or well stimulation. Evaluating the performance of a well also contributes to a better understanding of sweep, water production and cross flow, particularly in long reach wells. The most common flow regime at downhole conditions is a stratified flow regime in which lighter oil flows on top and heavier water flows on bottom. Slugging and bubbling flow regimes are typical of low oil flow rate and are considered unstable flow regimes. This paper described a new generation of production logging tools (PLTs) that have been used on some horizontal wet producers located in Saudi Arabia. The new PLTs consists of arrays of spinners and sensors to log the entire cross section to describe the horizontal flow regime and measure the downhole production and phases. In an effort to find the best logging procedure, the PLT was tested using two methods, notably coiled tubing (CT) and wireline tractor. It was concluded that PLTs are reliable and accurate. Case studies involving planning, deployment, data acquisition, and detailed analysis of PLTs were presented. 35 refs., 1 tab., 20 figs.

Partially pressure depleted reservoirs and unfavorable horizontal flow geometries can impact artificial lift designs and diagnostics. In addition, terrain slugging, drilling fines, high gas volume fractions, H{sub 2}S gas and high bottom hole temperatures also pose challenges. This paper provides an overview of various systems utilized by Amerada Hess, a company which examines methods of reducing gas lift gas volumes to achieve maximum flow. A description of naturally fractured reservoirs and limited natural fractures was provided. A comparison was presented between the original conditions at Beaver Lodge Madison and existing conditions with horizontal development. Various artificial lift challenges were examined. It was suggested that high volume lift utilizing gas lift was the preferred artificial lift system for high volume wells. It was noted that downhole sensors can be used as an indicator of potential run life. However, reliability is limited by downhole operating temperatures and electrical ground faults. A comparison of friendly and unfriendly flow systems was presented, as well as a gas lift pressure chart. A summary of average gas volume systems was provided as well as an example of a response to increase drawdown. Examples of downhole Electric Submersible Pump (ESP) sensors were provided, as well as possible flowing pressure profiles in horizontal completion because of the constraints of lift capacity. It was concluded that a single point injection and proven gas lift system is the next step in high volume lift strategy. 2 tabs, 16 figs.

A Compact Memory Logging (CML) system developed by Reeves Wireline Technologies was presented. It can be used to obtain log data from horizontal wells to get a better understanding of how to enhance production or completion techniques. The methods that are commonly used to obtain data from horizontal wells include measurement while drilling (MWD), logging while drilling (LWD), wet connect pipe conveyed wireline logging and CML. Each method has its unique benefits that range from information on lithology, rock parameters and fluid interfaces. Reeves has been using wireless pipe conveyed CML over the past two years. The log data includes array induction, dual spaced neutron and photo density porosity, Pe, gamma ray, compensated sonic and hose size caliper. Reeves CML is smaller, easily conveyed and has an unprecedented capability to bend and is considered to be well suited for both newly and previously drilled horizontal wells that require remedial assessment. The tool can be used to determine reservoir quality and boundaries, establish zone structures, or identify fluid interfaces for strategic planning of completions and stimulations. This paper presented examples of logs on some horizontal wells that indicate the value of obtaining log data. Reeves CML is considered to be economically and operationally ideal, particularly since data from the CML includes depth of investigation. 5 figs.

Full Text Available After several years of exploration practices in the Changning-Weiyuan national shale gas pilot zone, the industrial production has been achieved in a number of vertical and horizontal wells completed by SRV fracturing, and a series of independent shale gas reservoir stimulation technologies have come into being. Next, it is necessary to consider how to enhance the efficiency of fracturing by a factory-mode operation. This paper presents the deployment of Changning Well Pad A, the first cluster horizontal shale gas well group, and proposes the optimal design for the factory operation mode of this Pad according to the requirements of wellpad fracturing stimulation technologies and the mountainous landform in the Sichuan Basin. Accordingly, a zipper-fracturing mode was firstly adopted in the factory fracturing on wellpad. With the application of standardized field process, zipper operation, assembly line work, staggered placement of downhole fractures, and microseismic monitoring in real time, the speed of fracturing reached 3.16 stages a day on average, and the stimulated reservoir volume was maximized, which has fully revealed how the factory operation mode contributes to the large-scale SRV fracturing of horizontal shale gas cluster wells on wellpads in the aspect of speed and efficiency. Moreover, the fracturing process, operation mode, surface facilities and post-fracturing preliminary evaluation of the zipper-fracturing in the well group were examined comprehensively. It is concluded from the practice that the zipper-fracturing in the two wells enhanced the efficiency by 78% and stimulated reservoir volume by 50% compared with the single-well fracturing at the preliminary stage in this area.

Maximizing profits is the ultimate business objective in all drilling and completion operations. By far and away the biggest contributor to profits is the productivity of the well. Reliability and costs certainly impact profits; however, they pale in comparison to productivity when a rigorous calculation of net present value is performed. The simplest and most effective way to improve productivity is to increase the quantity of net reservoir exposed to the wellbore. A horizontal trajectory is the ultimate way to maximize the length of formation exposed to the wellbore. Drilling completion technology development over the last several years has made the use of horizontal wellbores in unconsolidated formations practical. Utilizing a unique mixture of new and existing technology, BP recently brought their first horizontal well in the Gulf of Mexico on line in record setting fashion. The planning, installation and results of this team effort are detailed in this operations oriented paper

Umiat oil field is a light oil in a shallow, frozen reservoir in the Brooks Range foothills of northern Alaska with estimated oil-in-place of over 1 billion barrels. Umiat field was discovered in the 1940’s but was never considered viable because it is shallow, in the permafrost, and far from any transportation infrastructure. The advent of modern drilling and production techniques has made Umiat and similar fields in northern Alaska attractive exploration and production targets. Since 2008 UAF has been working with Renaissance Alaska Inc. and, more recently, Linc Energy, to develop a more robust reservoir model that can be combined with rock and fluid property data to simulate potential production techniques. This work will be used to by Linc Energy as they prepare to drill up to 5 horizontal wells during the 2012-2013 drilling season. This new work identified three potential reservoir horizons within the Cretaceous Nanushuk Formation: the Upper and Lower Grandstand sands, and the overlying Ninuluk sand, with the Lower Grandstand considered the primary target. Seals are provided by thick interlayered shales. Reserve estimates for the Lower Grandstand alone range from 739 million barrels to 2437 million barrels, with an average of 1527 million bbls. Reservoir simulations predict that cold gas injection from a wagon-wheel pattern of multilateral injectors and producers located on 5 drill sites on the crest of the structure will yield 12-15% recovery, with actual recovery depending upon the injection pressure used, the actual Kv/Kh encountered, and other geologic factors. Key to understanding the flow behavior of the Umiat reservoir is determining the permeability structure of the sands. Sandstones of the Cretaceous Nanushuk Formation consist of mixed shoreface and deltaic sandstones and mudstones. A core-based study of the sedimentary facies of these sands combined with outcrop observations identified six distinct facies associations with distinctive permeability

Full Text Available During excavation of the Vinča-Belo Brdo site a significant number of decorated items made from clay, stone, bone, and seashells or snail shells have been collected over the years. Amongst the decorated objects which could be classified as jewellery the majority are bracelets, pendants, and beads made from Spondylus and Glycymeris shells, as well as beads made from Dentalium shells. The appearance of these beads and the question of their origin have not yet been specifically considered within studies of prehistoric cultures in the central Balkans. Furthermore, they have rarely been illustrated and mentioned in archaeological site inventories, which we presume has not been because of their poor representation, but rather because of their being unfamiliar. The aim of this work is therefore to: a systematize data about Dentalium beads from all phases of excavation of the Belo Brdo site in Vinča; b to show the importance of this kind of jewellery in the study of resources around the Vinča settlement; and c to indicate the wider chronological perspective and the significance of studying Dentalium beads within the prehistory of the central Balkans. Dentalium is a carnivorous Scaphopoda sea mollusc, uncommon and insufficiently studied. Representatives of this class of Scaphopoda have been found on Serbian territory in the Badenian sediments, deposited fifteen million years ago. Badenian sediments were discovered around Loznica, Belgrade, Aranđelovac, Golubac, Zaječar, and Negotin. The region of Belgrade and the surrounding area had been covered by a warm, shallow sea of normal salination. On the territory of Belgrade, offsprings of the Badenian sediments, rich in fossils, have been discovered in the city centre (Tašmajdan, Kalemegdan, as well as in many surrounding places (Rakovica, Kaluđerica, Leštani, and Jajinci (fig. 2. Scaphopod shells found at the Vinča-Belo Brdo archaeological site are usually transversally broken. Judging by the basic

Full Text Available The aim of this research was to analyze the horizontal spatial heterogeneity of both water and superficial sediment quality among and within the reservoirs of the Cantareira System (CS, focusing on concentrations of N and P, attributed to the dumping of raw domestic sewage into water bodies, which is the main cause of water pollution in São Paulo State (Brazil. The CS is a multi-system complex composed of five interconnected reservoirs, with water transported by gravity through 48 km of tunnels and channels. From the last reservoir of the CS, with an output of 33 m3 s−1, the water is conducted to a water treatment plant, producing half of the water consumed by 19 million people inhabiting São Paulo city. The upstream reservoirs are more eutrophic than the downstream ones. Data also suggest that the low phytoplankton biomass (ranging from 0.9 to 14.4 μg dm−3 is regulated by the low nutrient availability, mainly of phosphorus (TP ranging from below the detection limit, <9.0 μg dm−3, to 47.3 μg dm−3. For water, the DIN/TP ratios values range from 19 to 380. The upstream reservoirs function as nutrient accumulators and the sediment is the main compartment in which P and N are stored. Although the reservoirs are located in different river basins and are not in sequence along the same river, the results suggest a marked gradient between the reservoirs, with features similar to those of cascade reservoirs. The large volumes flowing through the canals and tunnels could explain the observed pattern. The CS reservoirs can therefore be considered multi-system reservoirs in cascade, constituting a particular case of multi-system reservoirs.

Three-dimensional reservoir modelling has become an accepted tool in reservoir description and is used for various purposes, such as reservoir performance prediction or integration and visualisation of data. In this case study, a small Northern North Sea turbiditic reservoir was to be developed with a line drive strategy utilising a series of horizontal producer and injector pairs, oriented north-south. This development plan was to be evaluated and the expected outcome of the wells was to be assessed and risked. Detailed analyses of core, well log and analogue data has led to the development of two geological {open_quotes}end member{close_quotes} scenarios. Both scenarios have been stochastically modelled using the Sequential Indicator Simulation method. The resulting equiprobable realisations have been subjected to detailed statistical well placement optimisation techniques. Based upon bivariate statistical evaluation of more than 1000 numerical well trajectories for each of the two scenarios, it was found that the wells inclinations and lengths had a great impact on the wells success, whereas the azimuth was found to have only a minor impact. After integration of the above results, the actual well paths were redesigned to meet external drilling constraints, resulting in substantial reductions in drilling time and costs.

The successful use of transverse hydraulic fractures from horizontal wellbores

Energy Technology Data Exchange (ETDEWEB)

Crosby, D. G.; Yang, Z.; Rahman, S. S. [New South Wales Univ., NSW (Australia)

1998-12-31

Since a significant proportion of the world`s recoverable hydrocarbon resources exist in reservoirs possessing permeabilities of less than one milli-Darcy (mD), some form of permeability enhancement or stimulation is necessary if the hydrocarbons are to be exploited economically. Multi-stage, transversely fractured horizontal wellbores are shown to have the potential to greatly increase production from low permeability formations. To overcome the problems caused by near-wellbore tortuosity, common to wells with multiple fracturing from the same perforated interval, a criterion was devised which predicts the wellbore pressures to initiate secondary multiple transverse hydraulic fractures in close proximity to primary fractures. The criterion, confirmed by laboratory experiments, demonstrates that transversely fractured horizontal wellbores have limited capacities to resist the initiation of multiple fractures from adjacent perforations. This characteristic can be used in designing hydraulic fracture treatments to establish injection pressure limits or threshold pressures, above which additional multiple fractures will initiate and propagate from the wellbore. 23 refs., 1 tab., 10 figs.

Numerical investigation of SAGD process using a single horizontal well

Shen, C. [imperial Oil of Canada, Calgary, AB (Canada)

1998-12-31

Numerical simulation studies have been pursued in an effort to evaluate some recent studies regarding the innovation and field application of the steam-assisted gravity drainage (SAGD) process using a single horizontal well to recover heavy oil. The simulation studies focused on (1) the possible counter-current fluid exchange pattern between reservoir and the well, (2) the means that could be exploited to promote the initiation of a steam chamber, and (3) the potential oil rates that could be expected under field operating conditions. Results showed that the presence of a small capillary pressure near the horizontal wellbore prevents counter-current exchange of steam and oil. However, vertical undulation in well-profile, or a certain level of formation dilution around the wellbore, have the potential to overcome the capillary pressure constraint and promote the initiation of a steam chamber under field conditions. Nevertheless, there remains considerable doubt about the effectiveness of the method. It is not considered to be economically feasible. 15 refs., 14 figs.

Comparison of simple, small, full-scale sewage treatment systems in Brazil: UASB-maturation ponds-coarse filter; UASB-horizontal subsurface-flow wetland; vertical-flow wetland (first stage of French system).

This paper presents a comparison between three simple sewage treatment lines involving natural processes: (a) upflow anaerobic sludge blanket (UASB) reactor-three maturation ponds in series-coarse rock filter; (b) UASB reactor-horizontal subsurface-flow constructed wetland; and (c) vertical-flow constructed wetlands treating raw sewage (first stage of the French system). The evaluation was based on several years of practical experience with three small full-scale plants receiving the same influent wastewater (population equivalents of 220, 60 and 100 inhabitants) in the city of Belo Horizonte, Brazil. The comparison included interpretation of concentrations and removal efficiencies based on monitoring data (organic matter, solids, nitrogen, phosphorus, coliforms and helminth eggs), together with an evaluation of practical aspects, such as land and volume requirements, sludge production and handling, plant management, clogging and others. Based on an integrated evaluation of all aspects involved, it is worth emphasizing that each system has its own specificities, and no generalization can be made on the best option. The overall conclusion is that the three lines are suitable for sewage treatment in small communities in warm-climate regions.

The ecological dynamics of Barra Bonita (Tietê River, SP, Brazil reservoir: implications for its biodiversity

JG. Tundisi

Full Text Available Barra Bonita reservoir is located in the Tietê River Basin - São Paulo state - 22° 29" to 22° 44" S and 48° 10° W and it is the first of a series of six large reservoirs in this river. Built up in 1963 with the aim to produce hydroelectricity this reservoir is utilized for several activities such as fish production, irrigation, navigation, tourism and recreation, besides hydroelectricity production. The seasonal cycle of events in this reservoir is driven by the hydrological features of the basin with consequences on the retention time and on the limnological functions of this artificial ecosystem. The reservoir is polymitic with short periods of stability. Hydrology of the basin, retention time of the reservoir and cold fronts have an impact in the vertical and horizontal structure of the system promoting rapid changes in the planktonic community and in the succession of species. Blooms of Microcystis sp. are common during periods of stability. Superimposed to the climatological and hydrological forcing functions the human activities in the watershed produce considerable impact such as the discharge of untreated wastewater, the high suspended material contributions and fertilizers from the sugar cane plantations. The fish fauna of the reservoir has been changed extent due to the introduction of exotic fish species that exploit the pelagic zone of the reservoir. Changes in the primary productivity of phytoplankton in this reservoir, in the zooplankton community in the diversity and organization of trophic structure are a consequence of eutrophication and its increase during the last 20 years. Control of eutrophication by treating wastewater from urban sources, adequate agricultural practices in order to diminish the suspended particulate matter contribution, revegetation of the watershed and riparian forests along the tributaries are some possible restoration measures. Another action that can be effective is the protection of wetlands in

A Novel Method for Performance Analysis of Compartmentalized Reservoirs

Directory of Open Access Journals (Sweden)

Shahamat Mohammad Sadeq

2016-05-01

Full Text Available This paper presents a simple analytical model for performance analysis of compartmentalized reservoirs producing under Constant Terminal Rate (CTR and Constant Terminal Pressure (CTP. The model is based on the well-known material balance and boundary dominated flow equations and is written in terms of capacitance and resistance of a production and a support compartment. These capacitance and resistance terms account for a combination of reservoir parameters which enable the developed model to be used for characterizing such systems. In addition to considering the properties contrast between the two reservoir compartments, the model takes into account existence of transmissibility barriers with the use of resistance terms. The model is used to analyze production performance of unconventional reservoirs, where the multistage fracturing of horizontal wells effectively creates a Stimulated Reservoir Volume (SRV with an enhanced permeability surrounded by a non-stimulated region. It can also be used for analysis of compartmentalized conventional reservoirs. The analytical solutions provide type curves through which the controlling reservoirs parameters of a compartmentalized system can be estimated. The contribution of the supporting compartment is modeled based on a boundary dominated flow assumption. The transient behaviour of the support compartment is captured by application of “distance of investigation” concept. The model shows that depletion of the production and support compartments exhibit two unit slopes on a log-log plot of pressure versus time for CTR. For CTP, however, the depletions display two exponential declines. The depletion signatures are separated by transition periods, which depend on the contribution of the support compartment (i.e. transient or boundary dominated flow. The developed equations can be implemented easily in a spreadsheet application, and are corroborated with the use of a numerical simulation. The study

In 2010, Petrolera Indovenezolana S.A. (PIV), a joint venture between Corporacion Venezolana del Petroleo (CVP) and the Indian company ONGC Videsh Limited (OVL), started planning for two horizontal wells in the Norte Zuata (San Cristobal) field in the Orinoco belt of eastern Venezuela. The focus for this campaign was to evaluate the productivity of horizontal wells in thin sands and avoid areas of complex geology because of the high uncertainty in the structural behavior, applying technology that provided absolute control of the drilling process into the Oficina formation. Within the Oficina formation, thin sand reservoirs with variations in thickness and dip, geologically facies changes and sub seismic faults presented the main challenge to geosteering a horizontal well. Because the project faced high geological uncertainties, a pilot hole was drilled as the first stage in the first well to verify the structural levels and the continuity of the sand bodies. To achieve the above challenges, the combination of a rotary steerable system (RSS) 'point-the-bit' and a deep azimuthal electromagnetic resistivity tool (DAEMR) was used. The measurements provided accurate information to the well-placement engineers for proactive decisions in real time, mitigating the possible loss of the target by these geologic uncertainties. High-quality and valuable data for real time geological model update were the expected results obtained from the effort made by PIV in the Norte Zuata (San Cristobal) field, and the data showed the oil-producing potential of one of the main reservoir (Sand F,G). This application of high-tier technologies demonstrated that drilling and data measurements can be improved and optimized to yield added value for reservoir development and 100% net to gross (NTG) targets. This reduces operational cost, makes it possible to drill in the right place the first time, and pushes forward the limit of the achievable in terms of reservoir exposure. (author)

Reservoir performance and characterization are vital parameters during the development phase of a project. Infill drilling of wells on a uniform spacing, without regard to characterization does not optimize development because it fails to account for the complex nature of reservoir heterogeneities present in many low permeability reservoirs, especially carbonate reservoirs. These reservoirs are typically characterized by: (1) large, discontinuous pay intervals; (2) vertical and lateral changes in reservoir properties; (3) low reservoir energy; (4) high residual oil saturation; and (5) low recovery efficiency. The operational problems they encounter in these types of reservoirs include: (1) poor or inadequate completions and stimulations; (2) early water breakthrough; (3) poor reservoir sweep efficiency in contacting oil throughout the reservoir as well as in the nearby well regions; (4) channeling of injected fluids due to preferential fracturing caused by excessive injection rates; and (5) limited data availability and poor data quality. Infill drilling operations only need target areas of the reservoir which will be economically successful. If the most productive areas of a reservoir can be accurately identified by combining the results of geological, petrophysical, reservoir performance, and pressure transient analyses, then this ''integrated'' approach can be used to optimize reservoir performance during secondary and tertiary recovery operations without resorting to ''blanket'' infill drilling methods. New and emerging technologies such as geostatistical modeling, rock typing, and rigorous decline type curve analysis can be used to quantify reservoir quality and the degree of interwell communication. These results can then be used to develop a 3-D simulation model for prediction of infill locations.

Investigating the effects of rock porosity and permeability on the performance of nitrogen injection into a southern Iranian oil reservoirs through neural network

In this work, a comprehensive model for Nitrogen injection into an oil reservoir (southern Iranian oil fields) was developed and used to investigate the effects of rock porosity and permeability on the oil production rate and the reservoir pressure decline. The model was simulated and developed by using ECLIPSE300 software, which involved two scenarios as porosity change and permeability changes in the horizontal direction. We found that the maximum pressure loss occurs at a porosity value of 0.07, which later on, goes to pressure buildup due to reservoir saturation with the gas. Also we found that minimum pressure loss is encountered at porosity 0.46. Increases in both pressure and permeability in the horizontal direction result in corresponding increase in the production rate, and the pressure drop speeds up at the beginning of production as it increases. However, afterwards, this pressure drop results in an increase in pressure because of reservoir saturation. Besides, we determined the regression values, R, for the correlation between pressure and total production, as well as for the correlation between permeability and the total production, using neural network discipline.

Advanced reservoir characterization and evaluation of CO2 gravity drainage in the naturally fractured Spraberry Trend Area. Annual report, September 1, 1996--August 31, 1997

The objective of the Spraberry CO{sub 2} pilot project is to determine the technical and economic feasibility of continuous CO{sub 2} injection in the naturally fractured reservoirs of the Spraberry Trend. In order to describe, understand, and model CO{sub 2} flooding in the naturally fractured Spraberry reservoirs, characterization of the fracture system is a must. Additional reservoir characterization was based on horizontal coring in the second year of the project. In addition to characterization of natural fractures, horizontal coring has confirmed a previously developed rock model for describing the Spraberry Trend shaly sands. A better method for identifying Spraberry pay zones has been verified. The authors have completed the reservoir characterization, which includes matrix description and detection (from core-log integration) and fracture characterization. This information is found in Section 1. The authors have completed extensive imbibition experiments that strongly indicate that the weakly water-wet behavior of the reservoir rock may be responsible for poor waterflood response observed in many Spraberry fields. The authors have also made significant progress in analytical and numerical simulation of performance in Spraberry reservoirs as seen in Section 3. They have completed several suites of CO{sub 2} gravity drainage in Spraberry and Berea whole cores at reservoir conditions and reported in Section 4. The results of these experiments have been useful in developing a model for free-fall gravity drainage and have validated the premise that CO{sub 2} will recover oil from tight, unconfined Spraberry matrix.

Research described In this report addresses the internal architecture of two specific reservoir types: restricted-platform carbonates and fluvial-deltaic sandstones. Together, these two reservoir types contain more than two-thirds of the unrecovered mobile oil remaining ill Texas. The approach followed in this study was to develop a strong understanding of the styles of heterogeneity of these reservoir types based on a detailed outcrop description and a translation of these findings into optimized recovery strategies in select subsurface analogs. Research targeted Grayburg Formation restricted-platform carbonate outcrops along the Algerita Escarpment and In Stone Canyon In southeastern New Mexico and Ferron deltaic sandstones in central Utah as analogs for the North Foster (Grayburg) and Lake Creek (Wilcox) units, respectively. In both settings, sequence-stratigraphic style profoundly influenced between-well architectural fabric and permeability structure. It is concluded that reservoirs of different depositional origins can therefore be categorized Into a ``heterogeneity matrix`` based on varying intensity of vertical and lateral heterogeneity. The utility of the matrix is that it allows prediction of the nature and location of remaining mobile oil. Highly stratified reservoirs such as the Grayburg, for example, will contain a large proportion of vertically bypassed oil; thus, an appropriate recovery strategy will be waterflood optimization and profile modification. Laterally heterogeneous reservoirs such as deltaic distributary systems would benefit from targeted infill drilling (possibly with horizontal wells) and improved areal sweep efficiency. Potential for advanced recovery of remaining mobile oil through heterogeneity-based advanced secondary recovery strategies In Texas is projected to be an Incremental 16 Bbbl. In the Lower 48 States this target may be as much as 45 Bbbl at low to moderate oil prices over the near- to mid-term.

There are currently 160 active drilling rigs in the Barnett shale play, and small early developments have now become large-scale operations. This presentation outlined methods currently used to improve the productivity of directional drilling and completion techniques in gas shale plays. Horizontal completions are used to control height growth and increase contact areas. A typical horizontal well casing program was described along with details of cement liner treatment programs. Charts of optimum and non-optimum azimuth wells were included. Increased reservoir contact has been achieved by using limited-entry designs and acid stages with ball-sealers and abrasive jet-cutters. Pump rates have been increased during various stages, and larger fluid and sand volumes were used. A mineralogy comparison was provided, as well as details of the general design criteria for vertical wells in the region. It was concluded that drilling in the Barnett shale play has been successful as a result of using 3-dimensional seismic mapping as well as by initiating multiple, simultaneous fracs. The presentation also included charts of the Arkoma-Woodford play, the Arkoma-Fayetteville play, and the Delaware Basin. tabs., figs.

Full Text Available OBJECTIVE: To evaluate the growth parameters in infants who were born to HIV-1-infected mothers. METHODS: The study was a longitudinal evaluation of the z-scores for the weight-for-age (WAZ, weight-for-length (WLZ and length-for-age (LAZ data collected from a cohort. A total of 97 non-infected and 33 HIV-infected infants born to HIV-1-infected mothers in Belo Horizonte, Southeastern Brazil, between 1995 and 2003 was studied. The average follow-up period for the infected and non-infected children was 15.8 months (variation: 6.8 to 18.0 months and 14.3 months (variation: 6.3 to 18.6 months, respectively. A mixed-effects linear regression model was used and was fitted using a restricted maximum likelihood. RESULTS: There was an observed decrease over time in the WAZ, LAZ and WLZ among the infected infants. At six months of age, the mean differences in the WAZ, LAZ and WLZ between the HIV-infected and non-infected infants were 1.02, 0.59, and 0.63 standard deviations, respectively. At 12 months, the mean differences in the WAZ, LAZ and WLZ between the HIV-infected and non-infected infants were 1.15, 1.01, and 0.87 standard deviations, respectively. CONCLUSIONS: The precocious and increasing deterioration of the HIV-infected infants' anthropometric indicators demonstrates the importance of the early identification of HIV-infected infants who are at nutritional risk and the importance of the continuous assessment of nutritional interventions for these infants.OBJETIVO: Evaluar los parámetros de crecimiento en lactantes nacidos de madres infectadas con el VIH-1.

In their constant effort to increase the production from Chicontepec, PEMEX drilled a multilateral well with three horizontal lateral sections; the intention was to increase the production in comparison with vertical wells. In the second arm of this well four intervals were identified to be fractured, this was a new approach since it was the first occasion that multiple fractures were planned in a horizontal well. An important part of the project was the evaluation of the effectiveness of the hydraulic fracturing. This evaluation was performed by micro seismic monitoring during the treatment. This technology allows the detection of events generated during the fluid injection in the reservoir, with receivers located in a nearby monitoring well. The interpretation of this data allows the identification in 3 D space of the fracture locations. This information is valuable for optimization of subsequent treatments and for planning the field development. The data is recorded in real time and can be used to make decisions during the fracturing operation. In this paper we describe the results of the hydraulic fracturing monitoring performed in four intervals in a horizontal well showing the geometry and direction of each one of the fractures.

Full Text Available Circulation of artifacts among cosplayers in Belo Horizonte and Vitória – This paper maps some relevant events for an understanding of the cosplay scene in Brazil’s southeastern state capitals. It discusses part of the interpretation of data collected during the Anime Winter Fest in Belo Horizonte, MG, in 2013, and the Vitória Anime Show in Vitória, ES, in 2013, based on a comparative analysis and considering the heterogeneity of the cosplay scene. Studies about the contemporary city and notions about circulation, as well as research about youth culture, are linked with reflections about material and media consumption in the cosplay scene, forming the theoretical framework and methodology on which this study is based.

Reservoir management

A reservoir's life begins with exploration leading to discovery followed by delineation of the reservoir, development of the field, production by primary, secondary and tertiary means, and finally to abandonment. Sound reservoir management is the key to maximizing economic operation of the reservoir throughout its entire life. Technological advances and rapidly increasing computer power are providing tools to better manage reservoirs and are increasing the gap between good and neural reservoir management. The modern reservoir management process involves goal setting, planning, implementing, monitoring, evaluating, and revising plans. Setting a reservoir management strategy requires knowledge of the reservoir, availability of technology, and knowledge of the business, political, and environmental climate. Formulating a comprehensive management plan involves depletion and development strategies, data acquisition and analyses, geological and numerical model studies, production and reserves forecasts, facilities requirements, economic optimization, and management approval. This paper provides management, engineers, geologists, geophysicists, and field operations staff with a better understanding of the practical approach to reservoir management using a multidisciplinary, integrated team approach

Full Text Available Horizontal wells show better affect and higher success rate in low water ratio cement, complex fracture zone, crevice and heavy oil blocks, it is the main measures to expand control area of a single well. Hydraulic fracturing technology is the most financial way to improve the penetration of the reservoir to increase the production. However, compare with the vertical wells, the fracture of Horizontal wells are more complex, and lead to the initiation crack pressure is much higher than vertical wells. In this paper, defined the crack judging basis, and established the finite element model which could compute the initial crack pressure, to research the affection mechanism of perforation azimuth angle, density, diameter and depth, to provide references of perforation project's design and optimize. The research of this paper has significances on further understanding the affection mechanism of perforation parameters.
