MPD technique manages drilling pressure to keep bottom hole Pressure balanced in the well. The objective to this studs, is to approximate the well pressure to formation pressure to prevent entry of fluid into the well. MPD is a new method drilling in which, driller controls the annulus pressure in order prevent drilling problems. the circulating fluids system employed by MPD technology is more akin to that of a pressure vessel. In this thesis, using in laboratory-made machine, reacts with sudden changes in pressure at the bottom hole in the shortest possible time. Basically, this system is a system where well bore pressure management is obtained by adjusting the pressures along the well bore... 

Acceptance of new technologies in an industrial field generally takes a long time, and needs accelerators and facilitators to be thoroughly and truly understood, accepted, and then implemented. One of the most useful accelerators is Feasibility Study, which help the specialists to be confident that the whole technical and economic aspects of the issue are considered in an overall view and the technology is totally feasible and beneficial.Managed Pressure Drilling which was introduced as a new technology to drilling industry internationally in 2003 and developed rapidly till now, is one of the most useful technologies in the oil and gas wells drilling industry, and helps the Operator...
