Each of two HPHT wells drilled by StatoilHydro using MPD technology in Norway’s Kvitebjørn Field have net present value of US$ 2 billion, and the operator will use MPD technology on all future Kvitebjørn wells, said Svein Erik Eide, StatoilHydro Head of Drilling and Well Technology. Mr Eide made his remarks during the 2008 SPE/IADC Managed Pressure Drilling and Underbalanced Operations Conference, 28-29 Jan., Abu Dhabi. He was presenting “Highly Advanced Multitechnical MPD Concept Extends Achievable HPHT Targets in the North Sea” (SPE/IADC 1114484).

The field has pressure of 770 bars (11,200 psi) and 150 C (300 ), and simultaneous drilling and production were planned. StatoilHydro’s stragety was to combine several technologies:

• MPD to provide control of the induced downhole pressure profile;
National Oilwell Varco’s Continuous Circulation System (CCS) to maintain a constant equivalent circulating density throughout;
• Balanced Mud Pill (BMOPa to rbing the well to overbalance for BHA handling and for reduced ECD compared to displaying a heavy mud at TD;
• Fracture Gradient Enhancement to increase the drilling window.

The paper will be more fully presented in a future edition of DC.
