Abstract
Blowout preventers, fluid pressure systems and portions thereof may be tested for leaks utilizing either a pressure decay rate method test or a volumetric leak rate method test of a hydrostatic pressure. The method provides for a means of resolving the nonlinear relationship between volumetric loss and test pressure utilizing either a pressure decay rate method test or a volumetric leak rate method test of a hydrostatic pressure test into a single dimensionless number that approximates the diameter of an orifice.
