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 core) to reservoir scale (e.g. 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. The subject that this volume deals with 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.
