Fracture and In-Situ Stress Characterization of Hydrocarbon Reservoirs
This publication introduces the newly developed, integrated discipline of fracture and in-situ stress characterization of hydrocarbon reservoirs, through 16 well-illustrated case studies. These cover a wide range of tools, from borehole Scale (logs and cores) to reservoir scale (3-D and 4-D seismic). It also covers surface studies (outcrop and remote sensing). In addition, it addresses the impact of fractures and in-situ stresses on fluid flows and their simulation.
This volume deals with a subject that is gaining increasing interest with the advancement of technologies and shifting boundaries of marginal fields into more challenging ground. Fractures and their response to current-day in-situ stresses have become a crucial part of reservoir characterization in deep tight reservoirs. In addition, maturing reservoirs, which were considered as ‘conventional’ at discovery, are displaying symptoms characteristic of fractures and/or geomechanical contribution. This has lead to the need to delineate the fractures and the stresses in these reservoirs and revise reservoir management accordingly.
The book will be of interest to a broad range of readers from both academic and industrial institutes, who are researching and dealing with hydrocarbon reservoir characterization, simulation and management.
Seismic volume attributes for fracture analysis
Published:January 01, 2003
Seismic volume attributes are introduced for the characterization of subtle fault patterns. These patterns are important in understanding the flow behaviour in reservoirs. The seismic attributes are based on neighbourhood analysis of the seismic signal and take 2D or 3D information into account. In the case of fracture systems, attributes such as coherency, that quantify change in the seismic signal are used. Case studies are presented to show the impact of the attribute analysis on the description of reservoirs.
