Advances in Geomechanics Research and Application for Deep Unconventional Reservoirs


Book Description

Deep unconventional oil and gas reservoirs (such as shale oil/gas, tight oil/gas, coalbed methane (CBM), oil shale, etc.) are commonly characterized by geological and structural complexity, increased formation temperature and pressure, and complex in-situ stress fields. Geomechanics research is helpful to understand the in-situ stress of complex structures, faults and natural fracture systems in deep blocks. Field practice shows that insufficient geomechanics understanding can easily result in low drilling efficiency, long construction period, frequent occurrence of complex situations, and unsatisfactory fracturing effects. In recent years, geomechanics applied to drilling, completion, hydraulic fracturing, and production in unconventional reservoirs has achieved great progress, producing various advanced experimental and numerical approaches and applications. However, as the buried depth increases, the complicated geology conditions make it more and more difficult for the engineering reconstructions, which poses a great threat to the efficient development of deep resources. New knowledge and understandings of geomechanics are urgently needed to guide the development of unconventional oil/gas reservoirs, and the related theory, experiment and simulation studies are rapidly developing.




Naturally Fractured Reservoirs


Book Description

This book deals exclusively with naturally fractured reservoirs and includes many subjects usually treated in separate volumes. A highly practical edition, Naturally Fractured Reservoirs is written for students, reservoir geologists, log analysts and petroleum engineers.




Development of Unconventional Reservoirs


Book Description

The need for energy is increasing and but the production from conventional reservoirs is declining quickly. This requires an economically and technically feasible source of energy for the coming years. Among some alternative future energy solutions, the most reasonable source is from unconventional reservoirs. As the name “unconventional” implies, different and challenging approaches are required to characterize and develop these resources. This Special Issue covers some of the technical challenges for developing unconventional energy sources from shale gas/oil, tight gas sand, and coalbed methane.




Advances in the Study of Fractured Reservoirs


Book Description

Naturally fractured reservoirs constitute a substantial percentage of remaining hydrocarbon resources; they create exploration targets in otherwise impermeable rocks, including under-explored crystalline basement; and they can be used as geological stores for anthropogenic carbon dioxide. Their complex behaviour during production has traditionally proved difficult to predict, causing a large degree of uncertainty in reservoir development. The applied study of naturally fractured reservoirs seeks to constrain this uncertainty by developing new understanding, and is necessarily a broad, integrated, interdisciplinary topic. This book addresses some of the challenges and advances in knowledge, approaches, concepts, and methods used to characterize the interplay of rock matrix and fracture networks, relevant to fluid flow and hydrocarbon recovery. Topics include: describing, characterizing and identifying controls on fracture networks from outcrops, cores, geophysical data, digital and numerical models; geomechanical influences on reservoir behaviour; numerical modelling and simulation of fluid flow; and case studies of the exploration and development of carbonate, siliciclastic and metamorphic naturally fractured reservoirs.
