Developing 3D Mechanical Models to Evaluate Reservoir Stability against Production Scenarios

Reservoir studies aim at understanding and describing the dynamic behavior of hydrocarbon reservoirs by properly integrating all available geological, geophysical, petrophysical and engineering information, in order to confidently predict the future performance of the field under different development and production strategies. Capturing and preserving the high complexity and heterogeneity that characterize the majority of the reservoirs' phases is the key starting point for accurate geomechanical analysis.  These include reservoir stability, prediction of reservoir compaction and subsidence, reservoir safety analysis, and enhanced recovery production planning.  As an example, producing hydrocarbons from highly stressed faulted reservoirs, either through primary depletion or enhanced recovery production, can result in unanticipated fault reactivation, leading to potential material impacts, loss of production and possibly the reservoir itself.  Enabling the integration of a high fidelity geological model with geomechanical simulation opens the door to an optimal management of the reservoir and control of production risks.
