... method (XFEM) is utilized to model displacement discontinuities arising from fractures. To model fracture aperture changes during depletion, a proppant model with linear elasticity is assumed. Moreover, to cope with complex fractures, we consider two basic types of fracture junctions, one is the ‘X’ type...

... Abstract The three-dimensional connectivity of the fluid phases in porous media plays a crucial role in governing the fluid transport, displacement, and recovery. Accurate three-dimensional quantification of the fluid phase connectivity following each fluid injection stage will lead to better...

Abstract The knowledge of the effects of instability and heterogeneity on displacements, primarily enhanced oil recovery and carbon dioxide storage, are well known though they remain difficult to predict. The usual recourse to modeling these effects is through numerical simulation. Simulation...
