| Abstract | In oil and gas wells drilling nowadays in the gulf of Thailand, we are close to decline period. Most of the wells are very deep, high temperture and high pressure that can create a lot of non productive times and also safety issues. Managed Pressure Drilling (MPD) has played an important role to help reduce drilling non productive time in different types of formation. By controlling of bottom hole pressure to be constant all the time both static (making connection) and dynamic (drilling) condition. MPD has been introduced to the gulf of Thailand couple years ago but still lack of activities due to it is new technologies, need more economical study, and also lack of experiences of drilling crews. Offshore Thailand conventional drilling problems such as tight hole, well control, and lost circulation can be mitigated by using MPD application. MPD main equipment consist of rotating centrol device and MPD choke manifold so that wellbore become close system in order to control bottom hole pressure to be constant by applying surface choke pressure. This paper makes analysis on conventional drilling in the gulf of Thailand and study screening process of MPD application by focusing on constant bottom hole pressure technique. The outcome of this paper are show the benefits of MPD include the ‘MPD decision flow diagram’ differentiates the results into ‘MPD not required’ and ‘MPD is help’ including details of MPD rig survey in the gulf of Thailand. MPD can be the next new technology for offshore Thailand operation, but it still needs some more studies in MPD equipment and operation knowledge to oil field people both engineering and operation teams as well as the rig contractor. |
