DOI: 10.1007/s10596-019-09843-6
Abstract: Wettability alteration is one of the most promising techniques to enhance oil recovery of mixed- or oil-wet reservoirs. As contact angle decreases within the matrix, the flux of fracture-matrix counter-current imbibition increases significantly. Wettability-altering agents… read more here.
