Abstract
An apparatusfor simulating a pulsed pressure induced cavitation technique (PPCT) from a pressurized working fluid (F) provides laboratory research and development for enhanced geothermal systems (EGS), oil, and gas wells. A pumpis configured to deliver a pressurized working fluid (F) to a control valve, which produces a pulsed pressure wave in a test chamber. The pulsed pressure wave parameters are defined by the pumppressure and control valvecycle rate. When a working fluid (F) and a rock specimenare included in the apparatus, the pulsed pressure wave causes cavitation to occur at the surface of the specimen, thus initiating an extensive network of fracturing surfaces and micro fissures, which are examined by researchers.
