Mechanical response of anisotropic rocks under hydraulic fracture conditions: new experimental insights (NERC grant NE/L009110/1)
Text data capturing pore fluid pressures (upstream and downstream), axial stress, axial and radial displacement were conditioned and logged by a high-speed data acquisition unit (NI-DAQ 6341) recording data at 10kHz. Two additional cantilever-type radial strain probes are attached directly to the sample at 90 degrees to each other, with an average output calculated via sqrt[(rA2 + rB2)], where rA and rB are the two radial outputs, to monitor an average radial strain and crack opening displacement.

- 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).
