ABERDEEN, UK – BP has contracted Omega Completion Technology to supply its Command Activated Sandface valves for the Clair Ridge project west of Shetland.
Production of the 4½” valves is under way, with delivery scheduled for February 2012.
Mark Buyers, managing director of Omega, said BP chose the equipment mainly as a result of service experience with a similar Omega completion valve in the Norwegian sector over the past four years.
According to Omega, placing the Sandface valves in the open hole sections allows the operator to sequentially clean up from the toe to the heel of the well. This offers a higher sweep of the reserves by allowing clean-up in stages instead of opening up all zones and flowing from the start.
No well intervention is needed to open the valves as they are programmed on the surface, says Omega, and Rig costs therefore can be kept down, due to a reduction in operations time and potential hazardous operations.
Omega has developed a high pressure variant that allows high pressure fracing operations to be conducted after initial clean-up of the well. BP previously used Omega valves in water production wells to clean up the well during start-up.
