Ikon Science on Tour - Integrating Pressure and Geomechanical Modeling with Geophysics 

Please join Ikon Science for lunch and to hear Ikon's Dr. Sam Green, Dr. Jeremy Meyer, and Dr. Alan Mur explain how you can enhance exploration and exploitation in unconventionals by integrating pressure and geomechanical modeling with geophysics.

Unconventional plays are known to be variably pressured horizontally and laterally. Pore pressure prediction using on-shore seismic data is not trivial as the relationship between porosity and overpressure is complicated by a complex geological history. The variation observed in seismic velocities may not relate directly to changes in pressure; for example, the presence of gas, and TOC can both act to slow the velocity which mimics a pressure response that is actually erroneous. 

Pore pressure is a critical input to a geomechanical model and can impact the mechanical behavior of the well. A well-based workflow has been developed which is able to predict the pore pressure and construct a geomechanical model that matches the wellbore measurements. The resultant models are then applied to a high resolution 3D seismic inversion encompassing key elastic properties and facies prediction to produce a 3D understanding of the distribution of pressure and stress.
