Minifrac – Hydraulic Fracturing System

Hydraulic fracturing involves the isolation of part of a borehole using an inflatable straddle packer and the subsequent pressurisation of the hole until the wall rock fractures. If an axial fracture is produced, the pressure record obtained during the test can be used to determine the magnitudes of the secondary principal stresses in the plane normal to the test hole axis.
