Managed Pressure Drilling (MPD) has been used around the world to help drill wells where there is a tight mud weight (MW) window, due to the ability of the technology to more accurately control annular bottom hole pressure (BHP) while drilling, tripping and during connections. This paper presents the case history of the Harding PNE2a well design and execution in 2012, with particular focus on the planning process, design methodology and execution particulars associated with the use of MPD as the enabling technology to drill, case and cement the well. The team also employed a novel Fluid Pressure Transmission Pill (FPTP) i , composed of a cross-linked polymer, to maintain hydrostatic pressure while tripping BHAs and during deployment of the liner and sand control equipment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
