Hydraulic Fracturing and Enhanced Recovery in Shale Reservoirs: Theoretical Analysis to Engineering Applications

“…4 Notable among these challenges is insufficient knowledge of the initiation and propagation of the hydraulic fracture, storage of gas, flow, structure of the shale reservoir in terms of its composition, and appropriate recovery technique to use. 5 Besides, the production from a single well declines so rapidly that low quantities of gas are recovered after a certain period because huge amounts of gas remain untapped despite the multiple fracturing strategies. 6−8 To address some of these challenges, different approaches have been adopted over the years and have registered a tremendous level of success.…”

“…Shale reservoirs are highly heterogeneous and are majorly characterized by low values of porosity and permeability, which necessitates the use of hydraulic fracturing and the drilling of horizontal wells to achieve efficient recovery. − During the exploitation of shale reservoirs, many engineering and technological challenges need to be addressed if maximum production is to be attained at minimal costs . Notable among these challenges is insufficient knowledge of the initiation and propagation of the hydraulic fracture, storage of gas, flow, structure of the shale reservoir in terms of its composition, and appropriate recovery technique to use .
