Managed Pressure Drilling (MPD) is a technology used to access challenging or partially depleted reservoirs, often and conventional wells prove expensive or deliver unsatisfactory results. The introduction and development of MPD techniques in land-based drilling for the past decade have facilitated the precise control of well-bore pressures. This, in turn, has provided improved well control by precise management of downhole pressures. Due to the operational advantages MPD can provide, during the past decade, an increasing number of operators are considering MPD for their offshore applications.
As the global leading provider of offshore classification services, ABS is deeply involved in the application of MPD technology into offshore projects. In response to this growing trend, ABS has worked closely with industry in developing classification requirements for MPD equipment and systems. These new requirements, part of the ABS Guide for the Classification of Drilling Systems, will be published in the first quarter of 2016and will lay out the approach needed in developing these systems.
The MPD system and all of its subsystems will be considered a part of the primary well barrier system. Therefore, for any ABS-classed rigs, all equipment systems and sub-systems used in MPD operations will require ABS MPD design approval for the equipment systems and subsystems. Additionally, an ABS survey will be required for installation of ABS-approved MPD equipment for ABS-classed rigs.
