Subsidence and Heave Modelling Using CMG Software

There is a strong interest in the modeling of reservoir fluid flow with geomechanical deformation. Coupling between reservoir flow and geomechanics has been discussed by many authors. Any coupling approach should satisfy, adaptability, Running speed and logical aspects to some degree. Three different widely used time-coupling techniques (one way, Iterative and full coupling) are reviewed and analyzed based on these three aspects. Fluid flow and geomechanics equation reviewed and injectionproduction case is studied to show heave and subsidence phenomenon when constitutive Laws is linear elastic or non-linear hyperelastic with different coupling method.
