ABSTRACT:
A method and apparatus is disclosed for testing a blowout preventer (BOP) by: using a drillpipe to install a test plug into one end of the throughbore of a (BOP); using a valve in the BOP to isolate the opposite end of the throughbore of the BOP, using piping to connect the output of a cementing unit to the throughbore of the BOP; using the cementing unit to increase the pressure in the throughbore of the BOP to a predetermined level; displaying the pressure in the piping as a function of time; and displaying the pressure in the piping as a function of time for the same blowout preventer system at an earlier time when leakage was deemed to be within predetermined acceptable limits. The pressure decline caused by a leak can be detected reliably and efficiently with high-resolution pressure data.
