Abstract

The behavior of reservoir rocks that are subjected to varying stress regimes throughout the life of a producing field has major impact on critical aspects of development and production including (1) reservoir drive and depletion planning, (2) wellbore stability and integrity, and (3) subsidence and overburden deformation. The subdiscipline of geomechanics straddles a zone that overlaps the geosciences and engineering and includes the study of the mechanisms and consequences of various models of reservoir compaction. Coupling geomechanical modeling with classical reservoir simulation honors the links between changes in the internal stress field and flow properties—allowing us to better estimate the long-term behavior of producing reservoirs. This paper reviews some underlying aspects of coupled simulation and provides references for further study.
