API RP 92M, 1st Edition, April 2023 - Managed Pressure Drilling Operations with Surface Back-pressure

This document provides information for planning, installation, testing and operation of wells drilled with surface back-pressure managed pressure drilling (MPD). This document applies only to drilling rigs with surface blowout preventers (BOPs).

This document considers situations where the total drilling operation is performed balanced or overbalanced, including both hydrostatically overbalanced (no supplemental surface pressure needed to control inflow) and hydrostatically underbalanced (supplemental surface pressure needed to control inflow) systems. See Annex A for guidance on planning and executing influx management using MPD techniques. For underbalanced operations, refer to API 92U.

This document does not cover MPD operations with subsea BOP stacks (see API 92S).
