... Abstract The paper presents a discussion on the issues related to the interaction between geomechanics and reservoir simulation in deformable hydrocarbon reservoirs. Geomechanics is important in order to account for rock deformations due to pore pressure and temperature changes resulting from...

... Abstract Pore collapse and the plastic behavior of high porosity chalks is well known but the extent to which harder, more moderate porosity carbonates are plastic is not as clear. We have experimentally determined the elastic and plastic deformation and effect of that deformation...

... Abstract In hydraulic fracturing technique, one of the questions is to determine fracture initiation pressure. The resolution of this problem should account for the coupling between material deformation, fluid flow and temperature variation. A finite element solution is proposed in this paper...

The inclusion of the surrounding domain leads to realistic modeling of the actual geomechanical boundary conditions...
