Abstract

Although the advances in the technology of hydraulic fracturing (aka fracking) of gas and oil shales have been nothing less than astonishing, the mechanics of hydraulic fracture and the orthotropic constitutive law of shale is still poorly understood and only about 5% to 15% of gas gets recovered from the fracked shale stratum. The purpose of this paper is to outline two recent theoretical advances at Northwestern University which should help to enhance the gas or oil recovery while also providing some environmental benefits, such as reduction of the amount of fracking water per unit of gas extracted.
