A computer based method expedites interpretation of pressure data during subsea blowout preventer (BOP) tests.  This can reduce the time and cost of current subsea BOP testing practices in a safe and objective manner.  The digital method employs computer software to produce an accurate model of the pressure decline behavior relatively early in each test.The model can thus predict if future pressures will stabilize at an acceptable level.  Comparison of the digital method to conventional subsea BOP testing on numerous field trials shows excellent agreement.  Working in concert with regulatory authorities to gain endorsement of this method is integral to the project.  Functionality of the software, example results and implementation status are reported.
