Hydraulic Fracturing in Homogeneous Media.

in: Proc. 32nd Gocad Meeting, Nancy

Abstract

Hydraulic fracturing (HF) or hydrofracking is a widely used technology for releasing oil and gas in low porosity reservoirs such as gas shales, tight gas, and coal seam gas. It consists in propagating fractures in a rock massif by the injection of incompressible pressurized fluids. Reservoirs are typically porous sandstones, limestones or dolomite rocks, but also include 'unconventional reservoirs' such as shale rock, and coal beds. This technology is also used to create permeability in hard rock geothermal sites. Hydraulic fracturing may also forms naturally in a number of geological processes including formation of dykes, veins, but also during migration of gas and petroleum from source rocks to reservoir This work proposed a theoretical framework for predicting propagation of fractures through time and space during a stimulation hydraulic fracturing test. It applies the poro-elastic theory coupled to the Mohr Coulomb and Griffiths failure theory for predicting the fracture orientations against distance from the injection well. The theory is developed in a porous homogeneous isotropic elastic medium, and then extended to an anisotropic layer.
