Statement

Hydraulic fracturing experiments were carried out in a triaxial deformation cell consisting of a servo-hydraulic axial and radial (confining) pressure system balanced to allow hydrostatic compensation, and a pore fluid injection pump (distilled water). A right cylindrical sample with centrally drilled conduit is prepared, and fitted with an internal steel guide/assembly to direct pressurized fluid into a section sealed using a number of O-rings. The entire sample assembly is separated from the confining medium using an engineered nitrile jacket. Experiments are carried out in two phases. Firstly, an initial triaxial stress (?1) and confining pressure (Pc) are applied until the required experimental (based on a desired Pc) conditions are established. Secondly, the experiment commences when water is injected at a constant flow rate (1mL/min).
