Abstract

Ivan Efendi. 101317063. Hydraulic Design For Constant Bottom Hole Pressure Managed Pressure Drilling (MPD) Operation In Narrow Drilling Window Well. The effect of a mature and depleted oil field is a narrow drilling window. This problem resulted in the well become more challenging to drill or impossible to drill when using a conventional drilling method. Therefore, the Managed Pressure Drilling (MPD) method is chosen to overcome the problem.The MPD sub-method applied to the drilling process is Constant Bottom Hole Pressure (CBHP) by controlling the bottom hole pressure constant using surface back pressure. Hydraulic simulation is conducted to determine the optimum hydraulic parameter to be used in CBHP-MPD operation using Landmark Software. Then, a hydraulic optimization analysis is simulated on the drilling simulation using the Herschel-Buckley rheology method.
