BOOK EXCERPT:

Deployment of expandable technology for sand control is experiencing rapid growth. While several expandable systems have been developed, assessment of their long-term performance and effectiveness has not. To alleviate some concerns and uncertainties, criteria are provided in this paper for assessing the possibility of sanding in wellbores that employ reticulated expandable completions and to illustrate an in-depth understanding of the mechanism under which such screens may prevent sand grain mobilization.

Experimental Study Of Mechanisms Of Sand Production Using X Ray Computerized Tomography

eBook Download

BOOK EXCERPT:

Durante a fase produtiva de um poço de petróleo ou gás, muitas vezes há a produção simultânea de partículas sólidas arrancadas da matriz da rocha reservatório. Este fenômeno recebe o nome de produção de areia. Neste caso as tensões e as condições de fluxo nas vizinhanças do poço são fatores fundamentais para a deflagração do processo. As tensões que se concentram na parede do poço com a perfuração do mesmo, pode ser de tal magnitude que pode causar a perda da coesão entre os grãos e criando, assim, uma região de material granular susceptível ao arraste pelas forças de percolação derivadas do fluxo. Este trabalho visou a realização de ensaios em amostras de arenito Rio Bonito e arenito sintético utilizando a técnica da Tomografia Computadorizada de RaiosX para acompanhamento em tempo real dos ensaios. Os ensaios tiveram por objetivo identificar a pressão de início e o modo de propagação da ruptura da parede da cavidade interna da amostra ensaiada. Estes são estágios iniciais dos processos de produção de areia em rochas. As análises das imagens tomográficas adquiridas durante os ensaios permitiram a visualização de breakouts e arrombamentos dos poços. Estudos mais detalhados possibilitaram estimar a quantidade de areia produzida e reconstruir tridimensionalmente o processo de propagação da ruptura.

Evaluation Of An Elastoplastic Model For Sand Production Studies In Oil Producing Rocks

eBook Download

BOOK EXCERPT:

Quando um poço de petróleo é completado em arenito brando e pobremente consolidado é possível que ocorra fluxo de areia para dentro do poço. Problemas derivados da produção deareia incluem a obstrução do poço, abrasão de revestimentos e ferramentas, colapso do revestimento e necessidade de separação e disposição, em superfície, de areias impregnadaspor óleo. Contudo, em reservatórios de óleo pesado, a alta viscosidade e abaixa produtividade significam que os problemas mencionados acima são menos críticos. Nestes casos, alguma produção de areia é aceitável para aumentar a produtividade. A produção de areia é notória em arenitos mal consolidados, mas também podem ocorrer em arenitos coesivos e medianamente resistentes como resultado da perturbação imposta à rocha durante as operações de perfuração, completação e produção Provavelmente o principal efeitoé a destruição da cimentação mineral que produz uma região com material granular na vizinhança do poço. As forças de percolação criadas pelo fluxo podem então arrastar aspartículas sólidas para o interior do poço. Um modelo contitutivo que seja capaz de reproduzir o comportamento tensão-deformaçãoresistência de arenitos é de grande interesse para estudos da previsão da produção de areia. Este tema é o ponto central desta tese. Uma revisão dos artigos relacionados com os mecanismos de produção de areia é apresentado no capítulo 2. Dois arenitos brandos obtidos de afloramentos foram caracterizados. Após a diagnosepetrográfica realizou-se o tratamento e processamento de imagens da lâminas para mensuração da distribuição granulométrica, parâmetros texturais e dimensão dos poros. Os argilominerais foram investigados por difração de raios-X, usando quatro tipos distintos de preparação de amostras. A porosidade e a permeabilidade intrínseca foram determinadas usando um porosímetro de Boyle e um permeametro à gás. Empregou-se um algoritmo para análise multivariada dos dados para distinguir entre grupos de arenitos com propriedades físicas semelhantes. Realizou-se um exercício numérico, usando soluções analíticas para a distribuição das tensões na parede de um poço, com o objetivo de se identificar as possíveis trajetórias de tensão que ocorrem, considerando as tensões in situ, a perfuração e a produção de fluidos. Foi desenvolvido um programa experimental de ensaios mecânicos que inclui testes uniaxiais, triaxiais convencionais e hidrostático, além de carregamentos seguindo a trajetória de pconstante. Estes ensaios serviram para obtenção dos parâmetros do modelo de Lade, bem como para caracterizar o comportamento geomecânico dos arenitos. Deve-se mencionar que os corpos de prova estavam totalmente saturados com água e com óleo. Usou-se um algoritmo de otimização para identificação dos parâmetros do modelo. Por fim, avaliou-se a capacidade do modelo elastoplástico de Lade & Kim para descrever o comportamento tensão deformação dos arenitos estudados.

Economically And Environmentally Sustainable Enhanced Oil Recovery

eBook Download

BOOK EXCERPT:

There have been many books on the topic of Enhanced Oil Recovery (EOR) over the last 100 years. They all, however, focus on how to recover more oil faster, taking a rather myopic approach. The solutions presented all work fantastically in theory and even in the laboratory, but each fails to produce results in the field with long-term success. The petroleum industry is almost resigned to the belief that for an EOR technique to be successful, it must be propped up with public funds or must compromise environmental integrity. In line with modern engineering practices, previous books discuss how existing technologies can be tweaked to accommodate for any shortcomings that just came to light. This book is unlike any other book on the topic of recovery in particular and engineering in general. This groundbreaking volume is a continuation of the author’s and his research group’s work that started publishing on the subject of global sustainability involving energy and the environment, dating back to early 2000s. Starting with a paradigm shift in engineering that involves a long-term focus, rather than looking for short-term solutions, the methods and theories presented here delve into applying green engineering and zero waste principles to EOR. Historically, EOR has received mixed success, mainly because innovations in these disciplines relied heavily on processed materials, which are both uneconomical and toxic to the environment. This book explains how engineers missed entirely the causes of unsustainability in these technologies due to the prevalence of many myths that are embedded in modern engineering. Once these myths are deconstructed, the appropriate technologies emerge and the merits of them both in terms of economic and environmental benefits become clear. The book reveals how previous practices in EOR can be replaced with their sustainable versions while saving in material costs. A number of innovative technologies are introduced that can render well known technologies, such as steam flood, in situ combustion, chemical flooding, and microbial EOR environmentally sustainable and economically attractive. A triple dividend is received once these technologies are applied in otherwise marginal reservoirs, unconventional plays and even abandoned formations. The overall reserve, which reflects recoverable oil with new technologies, goes up drastically. Further benefits are drawn when processes such as value addition of waste material is performed. Overall this book shows how EOR can be rendered green while increasing the profitability. This is in stark contrast to the past practices that considered environmental integrity as a drain on profitability. This book proves that a paradigm shift can turn a “technological disaster” into a technological marvel.

Sand Production Simulation Under True Triaxial Stress Conditions

eBook Download

BOOK EXCERPT:

Sand production in weakly consolidated sandstone reservoirs could result in damaging the production and surface facilities. Sanding includes two stages: the failure of sandstone around the borehole and sand grains being transported into the borehole. The first stage is related to stresses around the borehole whereas the second one is controlled by drawdown pressure. In order to avoid sanding, the stresses around the borehole and the drawdown pressure which initiate sanding are studied.
