FRACLAB Hydraulic fracture test system

The FRACLAB Hydraulic Fracture Test System warrants hydraulic fracture experiments with micro-seismic activity monitoring under various triaxial stress states and elevated temperatures. The device comprises a deviatoric triaxial cell equipped with an acoustic emission monitoring system. Four servo-controlled syringe pumps are utilized to control confining, axial, pore and fracturing fluid pressures. A lifting mechanism facilitates specimen setup. The apparatus determines specimen breakdown pressure at given confining and pore pressures, after which the tensile strength and frac-coefficient are computed. The acoustic emission (AE) monitoring system allows the characterization of fracture growth during geotechnical studies, e.g. hydraulic fracturing. Useful AE characteristic parameters, including hit counts, energy, amplitude, event duration and AE hypocenter localization are determined. Moreover, precise in-vessel deformation sensors measure diametral and axial strains during the test.
