GATE Prho™: Subsurface Safety Valve (SCSSV) Test Analysis

GATE Prho™ has been used on Gulf of Mexico assets to promote safer well operations through one of its features: rigorous Surface-controlled Subsurface Safety Valve (SCSSV) test analysis. It improves the commonly used SCSSV test protocol in the industry by accounting for the effects of liquid-gas interface existence in the wellbore, wellbore cooldown and suspected leakage through Underwater Safety Valve (USV) during the SCSSV test.  It helps the operator to accurately detect SCSSV malfunction.
