DOI: 10.1007/s00603-019-01851-3
Abstract: Naturally fractured rock mass is highly inhomogeneous and contains geological discontinuities at various length scales. Hydraulic fracture stimulation in such a medium could result in complex fracture systems instead of simple planar fractures. In this… read more here.

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.
