The definition of MPD recently adopted by the IADC Underbalanced Operations and Managed Pressure Committee states that: “Managed Pressure Drilling (MPD) is an adaptive drilling process used to precisely control the annular pressure profile throughout the wellbore. According to drilling specialists, bottomhole pressure is normally maintained above pore pressure by controlling the density of the drilling fluid. When density gets too high, the formation begins to absorb the fluid and the fluid density needs to be adjusted. Casing must be run to isolate the open hole before drilling can continue. The common objective of all currently known managed pressure drilling techniques is to stretch or eliminate casing points to allow drilling beyond conventional limits of depth or pressure variation.

Advanced Drilling Technology: Mapping-While-Drilling

Oil and Gas drilling teams usually contend with tight schedules for project developments and this may eventually lead to low quality plans and limited risk assessment, which may cause expensive and potentially dangerous drilling problems, such as, stuck pipes, violent kicks, unproductive time and cost overruns. The introduction of Schlumberger’s reservoir mapping-while-drilling service is enabling drillers to make better decisions in short timeframes and avoid costly mistakes. For the operators, the main benefits from the effective well placement may be maximized production, minimized construction and intervention costs. The process of well placements brings together many different disciplines…
