FRACLAB Hydraulic fracture test system

The FRACLAB Hydraulic Fracture Test System is designed to conduct hydraulic fracturing experiments while enabling micro-seismic activity monitoring under various triaxial stress conditions and elevated temperatures. The apparatus features a deviatoric triaxial cell integrated with an acoustic emission (AE) monitoring system. It employs four servo-controlled syringe pumps to regulate the pressures of the confining fluid, axial load, pore fluid, and fracturing fluid. A built-in lifting mechanism aids in specimen positioning. The system is capable of determining the breakdown pressure of a specimen under specified confining and pore pressures; subsequent to this, tensile strength and frac-coefficient values are calculated. The AE monitoring system offers insights into fracture growth for geotechnical investigations like hydraulic fracturing. It provides a range of characteristic AE parameters, including hit counts, energy levels, amplitude, event durations, and AE hypocenter localizations. Additionally, the apparatus is equipped with high-precision in-vessel deformation sensors that measure both axial and diametral strains throughout the test.
