    Well Enhancer completes first well intervention job

    Vessel & ROV News // December 17, 2009

    Well Enhancer recently completed its first well intervention project.

    Helix Well Ops UK, a subsidiary of Helix Energy Solutions Group Inc, says the latest addition to its well intervention fleet, Well Enhancer, has successfully completed the vessel's inaugural well intervention project, on behalf of Nexen Petroleum UK on the Buzzard S2 well in the North Sea, 60 miles east of Aberdeen.
    The Subsea Intervention Lubricator, (SIL), a 7-3/8in bore single-trip system designed and built in house by Helix Well Ops UK, was successfully deployed via the vessel’s integrated skidding and handling system. Working in adverse weather conditions with significant wave heights in excess of five metres and winds of 45 knots, heave at the moonpool rarely exceeded 2m and the vessel’s performance exceeded expectations.
    Steve Nairn, Vice President of Helix Well Ops UK, said: “Well Enhancer’s moonpool design and skidding system, coupled with our ability to disconnect and reconnect the control umbilicals subsea, enabled us to work safely in weather conditions that would have sidelined other intervention vessels. These features, unique to Well Enhancer, allowed the operation to be completed on schedule in spite of difficult weather.”
    Over the course of the 10 day operation, Well Enhancer performed production logging, fluid sampling and wireline services, including sand detection and flow profiling on the well. The S2 water injection well was entered with a combined log/fluid sampling service, with additional sand detection and flow profiling equipment onboard.  All on-board systems were utilised successfully.
