The method for rapid installation of smaller diameter pressure control device usable on blow out preventors, by installing a threaded profile flange with a bell nipple upon a BOP, installing a test plug in the base of the BOP or base of a stack of BOPs, installing a test plug into the threaded profile of flange, performing a pressure test on the flange and all sealing aspects of the BOP, depressurizing the flange and removing the test plug, installing a thread protector between the flange and the bore of the BOP, initiating drilling operations, and upon indication of the need for wireline or other small bore type operations, adapting the existing BOP to smaller working diameter pressure control device, removing the thread protector and installing a high pressure assembly to facilitate the small bore well operations.
