Paper Number: ARMA-2015-059
... Abstract Studies of hydraulic fracturing in fractured porous medium have commonly been made using in-situ fracture pressure upon the fracture (wing-crack) surfaces. Here we propose a novel technique, which may provide advantages such as increasing the rate of crude oil production from shallow...
