... on computation of effective stresses from ΔT andΔp, then assessing the state of the rock to see if and how much it shears and dilates. These processes are ill-quantified at present, so it is necessary to monitor. The two monitoring domains that are of greatest interest to coupled geomechanics simulation...

..., which can increase or decrease the effective stress in the reservoir. Thus, deformations can occur in some regions. Likewise, the deformations of the oil sand material (skeleton and pores) changes the fluid flow related reservoir parameters [5]. porosity reservoir simulation geomechanical...

... Abstract Solution gas libration is one of the key factors contributing to the success in solution gas drive in heavy oil reservoirs. Unconsolidated sands dilate with decreasing effective stress, and contract with increasing effective stress. This paper describes special experiments that were...

..., the directions of the principal values of permeability are not restricted to some arbitrary axes, and governed by the induced strains. Thus, the effects of stress paths and stress level are implicitly considered through effective stress-strain constitutive laws. The transient pressure response of a water...

Model calculations demonstrate that the fluctuations of effective stresses and shear stresses may reach several hundred kPa because of the pressure wave created by a water hammer inside the wellbore. The model can...
