STRAUME, Norway – AGR is joining Statoil to develop a new managed pressure drilling (MPD) system for floating drilling rigs.
The project will build on two established technologies. One is AGR’s EC-Drill system, which has been deployed this year on two deepwater wells in the Gulf of Mexico – a shallow-water version was used previously offshore Brazil, Egypt, and in the Caspian Sea.
EC-Drill addresses issues associated with drilling close to the fracture pressure, manipulating bottomhole pressure by changing the level of drilling mud in the riser.
The second technology is the Low Riser Return System developed by Ocean Riser Systems, which recently merged with AGR’s Enhanced Drilling Solutions (EDS) subsidiary to form EDS-ORS.
