... of this paper is to explore the effects of existence of discontinuities (e.g. fractures or fissures) in caprock, loading conditions, and steam chamber evolution, on surface heave, joint normal and shear displacements. Different modes of failure under various scenarios are presented for fissured and non-fissured...

... to displace oil. Under unfavorable mobility contrast, the interface between two fluids may become very convoluted as displacements continue. This therefore increases the contact area and leads to more efficient mixing. It is necessary to accurately simulate the detailed frontal instability and its propagation...

... in heavy oil reservoirs, high oil viscosity results in early breakthrough and poor sweep efficiencies. Polymers have been used to increase the displacing water viscosity for conformance control and viscous fingering attenuation. However, polymer degradation and entrapment inside the reservoir make them...
