Paper presented at the SPE/IADC Managed Pressure Drilling and Underbalanced Operations Conference and Exhibition, October 29–30, 2020
Paper Number: SPE-200514-MS
... Abstract Implementation of Managed Pressures Drilling (MPD) techniques provide substantial advantages for addressing difficulties in challenging wells. These benefits include not only the early influx and loss detection, but also Dynamic Influx Management. MPD provides the ability to circulate...
