Geomechanics is the discipline dealing with the prediction and management of rock deformation and failure. Geomechanical problems resulting from the change of stress in the rock induced by drilling and production make many hydrocarbon production projects challenging. Examples of geomechanical problems include wellbore stability and fracturing of the formation during drilling that may lead to financial loss due to losses, kicks, stuck pipe, extra casing strings, and sidetracks. Other problems are due to reservoir stress changes occurring during production such as reservoir compaction, surface subsidence, formation fracturing, casing deformation and failure, sanding, reactivation of faults, and bedding parallel slip.
