标准摘要
This document provides information for planning, installation, testing and operation of wells drilled, cased, cemented, completed or abandoned with controlled mud level (CML) managed pressure drilling (MPD). This document applies only to drilling rigs with a marine drilling riser and subsea blowout preventers (BOPs). This document considers situations where the total drilling operation is performed balanced or overbalanced, including both hydrostatically overbalanced and when mud level is reduced during circulation to a level where supplemental annular friction pressure may be required to stay overbalanced. Installation, testing, and use of the subsea BOP and associated well control equipment is the same as for conventional drilling operations and is not included in this publication. Refer to API Standard 53 for information regarding installation and testing of BOPs in a conventional drilling operation.
