Numerical investigation of the perforation friction loss, coefficient of discharge and erosional processes during limited entry hydraulic fracturing treatments
Hydraulic fracturing is behind the successful and feasible exploitation of unconventional hydrocarbon resources around the world. Pioneered by North American operators, the multi-stage massive treatments have enabled producing shale resources very efficiently and at a competitive cost. Recently, limited entry perforating has been found to be useful to increase the stage length and reduce the total stage count with no compromise on productivity. Limited entry hydraulic fracturing treatments rely on the concept of limiting the number of perforations, creating a high perforation frictional loss, ...
