... porosity and true porosity can be established from equation (1) and (2) as: (3) ϕ * = ϕ ( 1 − ε v ) where ε v is the volumetric strain. The sign convention adopted in this paper is positive for compressive stress and compressive strain. This method, first proposed in Ref...

... Abstract Yale et. al. 1 showed significant differences between "uncoupled" reservoir simulations of a highly compressible (but elastic) reservoir and the same model run with deformation and fluid flow "coupled" together. This paper utilizes a similar model but investigates the effect...
