Geomechanics is used to analyse drilling risks; pre-drill, during drilling and post-drilling. By integrating technical data from geology, petrophysics and reservoir engineering data models in 1D, 3D and 4D can be developed that are useful to drilling. Well bore stability is affected by rock stresses that can cause a collapse.
Safe well trajectories can be identified in a 3D geomechanical field and completions can be designed that will withstand production-induced compaction.
At the reservoir level, geomechanical models can be used to analysis pore pressure, fault and top seal integrity, compaction, subsidence and the effects of injection / depletion on cap rock behaviour.
