Managed Pressure Drilling Operations — Pressurized Mud Cap Operations with Subsea Blowou
Description
This document addresses recommended practices for pressurized mud cap drilling (PMCD) from a floating rig with a subsea BOP stack. When massive lost circulation conditions are encountered one of the following drilling methods may be implemented to allow well construction operations to continue: a) blind drilling; b) continuous annular injection drilling; c) floating mud cap drilling; d) pressurized mud cap drilling (PMCD). Although this document only addresses PMCD, most of the equipment described may also be used for the surface back-pressure (SBP) method of managed pressure drilling. However, much of the equipment used for SBP is not required for PMCD and is beyond the scope of this document.

Abstract
This document addresses recommended practices for pressurized mud cap drilling (PMCD) from a floating rig with a subsea BOP stack. When massive lost circulation conditions are encountered one of the following drilling methods may be implemented to allow well construction operations to continue: a) blind drilling; b) continuous annular injection drilling; c) floating mud cap drilling; d) pressurized mud cap drilling (PMCD). Although this document only addresses PMCD, most of the equipment described may also be used for the surface back-pressure (SBP) method of managed pressure drilling. However, much of the equipment used for SBP is not required for PMCD and is beyond the scope of this document.
