Book Description
Les réservoirs fracturés naturellement occupent la première place dans les réserves mondiales et forment une classe très particulière des réservoirs d'hydrocarbures. Leur étude est très spécifique et complexe à cause de l'existence de la porosité et de la perméabilité secondaires caractéristiques des réseaux de fractures. Les fluides s'écoulent essentiellement à travers un réseau de fractures tandis que la grande quantité de pétrole est emmagasinée par la matrice rocheuse, ce qui rend la production de pétrole à partir de ces réservoirs difficile et un grand défi pour les ingénieurs pétroliers. Lors de la récupération secondaire ou tertiaire dans les réservoirs fortement fracturés, l'injection de fluides de faible viscosité, tels que le gaz ou l'eau, conduit généralement à des percées précoces de fluides (canalisation de fluide ou channeling) dans les puits de production, entraînant ainsi une mauvaise efficacité, à l'échelle microscopique et macroscopique, de la récupération de pétrole. Le challenge pour les opérations de la récupération chimique améliorée du pétrole (cEOR) dans les réservoirs fracturés, c'est d'empêcher ce phénomène de canalisation des fluides « channeling », afin que les fluides injectés puissent entrer, se mettre en contact et déplacer l'huile piégée dans la matrice. Ces opérations sont connues sous le nom de « contrôle de conformance ». Dans un réservoir fracturé, la conformance peut être améliorée en réduisant la perméabilité secondaire des fractures par l'utilisation des systèmes de gels, de la mousse ou de la croissance microbienne. L'objectif de cette thèse est d'étudier la gélification d'un système de gel polymère formé par les polyacrylamides partiellement hydrolysés (PAPHs) et les polyethylenimines (PEIs). Pour des réactifs bien caractérisés, le temps de gélification, la force du gel et la stabilité thermique du gel sont étudiés en fonction des principaux paramètres physico-chimiques du système (PAPH/PEI). La méthode des surfaces de réponses (MSR) est utilisée pour développer un modèle mathématique qui permet la prédiction du temps de gélification des systèmes (PAPH/PEI) dans l'intervalle de températures compris entre 70 et 90 °C. Les mécanismes de réticulation, du PHPA avec de la PEI, sont ensuite étudiés et quantifiés à l'aide des techniques avancées.

Book Description
Written by foremost experts in the field, and formulated with attention to classroom use for advanced studies in reservoir characterization and processes, this book reviews and summarises state-of-the-art progress in the field of enhanced oil recovery (EOR). All of the available techniques: alkaline flooding; surfactant flooding; carbon dioxide flooding; steam flooding; in-situ combustion; gas injection; miscible flooding; microbial recovery; and polymer flooding are discussed and compared. Together with Volume I, it presents a complete text on enhanced recovery technology and, hence, is an almost indispensible reference text.This second volume compliments the first by presenting as complete an analysis as possible of current oilfield theory and technology, for accomplishment of maximum production of oil. Many different processes have been developed and field tested for enhancement of oil recovery. The emerging philosophy is that no single process is applicable to all petroleum reservoirs. Each must be treated as unique, and carefully evaluated for characteristics that are amenable to one or two of the proven technologies of EOR. This book will aid the engineer in field evaluation and selection of the best EOR technology for a given oilfield. Even the emerging technology of microbial applications to enhance oil recovery are reviewed and explained in terms that are easily understood by field engineers.The book is presented in a manner suitable for graduate studies. The only addition required of teachers is to supply example problems for class work. An appendix includes a reservoir mathematic model and program for general application that can also be used for teaching.

Book Description
Fundamentals of Enhanced Oil Recovery Methods for Unconventional Oil Reservoirs, Volume 67 provides important guidance on which EOR methods work in shale and tight oil reservoirs. This book helps readers learn the main fluid and rock properties of shale and tight reservoirs—which are the main target for EOR techniques—and understand the physical and chemical mechanisms for the injected EOR fluids to enhance oil recovery in shale and tight oil reservoirs. The book explains the effects of complex hydraulic fractures and natural fractures on the performance of each EOR technique. The book describes the parameters affecting obtained oil recovery by injecting different EOR methods in both the microscopic and macroscopic levels of ULR. This book also provides proxy models to associate the functionality of the improved oil recovery by injecting different EOR methods with different operating parameters, rock, and fluid properties. The book provides profesasionals working in the petroleum industry the know-how to conduct a successful project for different EOR methods in shale plays, while it also helps academics and students in understanding the basics and principles that make the performance of EOR methods so different in conventional reservoirs and unconventional formations. - Provides a general workflow for how to conduct a successful project for different EOR methods in these shale plays - Provides general guidelines for how to select the best EOR method according to the reservoir characteristics and wells stimulation criteria - Explains the basics and principles that make the performance of EOR methods so different in conventional reservoirs versus unconventional formations

Book Description
Fossil fuels, especially petroleum, are still the primary energy source all over the world. With the advent of hydraulic fracturing (i.e. "fracking"), directional drilling, and other technological advances, petroleum and reservoir engineers all over the world have been able to produce much greater results, in much more difficult areas, than ever before, to meet higher global demand. "Enhanced oil recovery (EOR)" is one of the hottest and most important topics in this industry. New technologies and processes must be continually discovered and developed, even as renewable energy begins to grow and become more fruitful, as the demand for more and more energy continues to grow worldwide. This groundbreaking and highly anticipated study discusses the scientific fundamentals of resonance macro- and micro-mechanics of petroleum reservoirs and its petroleum industry applications. It contains an overview of the research and engineering results of resonance macro- and micro-mechanics of petroleum reservoirs, which provide the scientific and applied foundations for the creation of groundbreaking wave technologies for production stimulation and enhanced oil recovery. A valuable tool for the petroleum or reservoir engineer in the field, this volume is also intended for students, teachers, scientists and practitioners who are interested in the fundamentals, development, and application of leading-edge technologies in the petroleum industry and other industrial sectors.
