The results of this UNFC case study identified producing, justified for development, and contingent projects...

... introduced in Zheng et al. (2019) . Abstract Lab experiments and numerical modeling have indicated that gas injection for IOR in tight oil reservoirs is technically feasible. Several operators have conducted pilots in the Eagleford and Bakken shales for a huff-n-puff IOR strategy with mixed results...

... The new semianalytical method is demonstrated to provide an accurate estimation of HF properties and dynamics, such as initial fracture pore volume and permeability, as well as fracture compressibility and permeability modulus, based on flowback and long-term production data of the shale oil reservoir...

... Abstract Steam assisted steam drainage (SAGD) or steam and gas push (SAGP) is commercially utilized to recover bitumen from oil sands. It produces higher oil rate and ultimate recovery than the other thermal recovery methods. But for thin heavy oil reservoirs, the recovery is lower resulting...
