Managed Pressure Drilling (MPD)

Managed Pressure Drilling (MPD) is an enclosed and pressurized system, which is operated in conventional and unconventional reservoirs in which the drilling window is narrow and to reduce fluctuations in BHP. The technology provides reduced drilling cost, NPT and certainty in operations. This paper mainly describes the equipment required, functioning and applications of MPD. The MPD technology is an advanced drilling optimization process which uses an advanced kick detection and well control approach. Variations of MPD are listed among which CBHP is discussed in the paper. The methods for achieving of CBHP are DAPC services, Rig diverter system are discussed. The applications of MPD in ERD and HPHT wells are briefly discussed in the paper which provides the improved performance of this technology. In addition with all this increase in safety, economical feasibility and wellbore stability is attained from the MPD which makes it as a selected application in drilling industry.
