Valiant drilling successfully with a customised MPD system

The Maersk Valiant presented an opportunity for ConocoPhillips and Marathon Oil to bring a state-of-the-art seventhgeneration drillship into the Gulf with an MPD system. The system needed to handle high and low flow rates, large cuttings and a high cuttings volume, and measure flow more accurately. Rather than just counting pump strokes, our customers wanted flow meters on all pumps, and to be able to feed this data into their hydraulics model. Maersk Drilling and the Maersk Valiant crew successfully drilled two challenging wells using this customised MPD system.
