Mass transport within the fracture-matrix systems of unconventional shale reservoirs : application to primary production and EOR in Eagle Ford
The average primary oil recovery factor of Eagle Ford shale is around six percent; thus, a considerable amount of oil will be left behind after primary production. A major technique to enhance oil production in Eagle Ford could be gas injection because waterflooding does not seem plausible. This thesis evaluates the potential of gas injection enhanced oil recovery (EOR) using dual-porosity compositional modeling. The modeling effort focuses on three areas: transport mechanism at the matrix fracture interface, rock deformation effect on the phase behavior in the matrix pores, and multi-phase ...
