Westside: Deepwater Wellbore Cleanup: Tools, Processes, Case Histories

In deepwater and extended-reach wells good system hydraulics are important for assuring the maximum annular velocity needed to prevent debris from settling on the low side of the hole.  Wellbore cleanup systems are used to reduce nonproductive time by effectively removing that debris.  A new system of deepwater wellbore cleanup tools has been developed, which features high torque and tensile ratings, a new bearing technology for high rotation speeds, and larger flow areas.  These high performance tools, which won the 2012 World Oil Award for Best Wellbore Intervention Technology, include casing scrapers and brushes, downhole magnets, multi-task wellbore filters, and riser brushes.  A new ball-activated circulation valve that can be opened and closed multiple times to perform a variety of operations and a new wellbore test packer that prevents damage to the liner top will also be discussed.  Case histories will be presented  that demonstrate how multiple operations can be performed in a single run, thereby further reducing rig time, improving reliability, reducing operational risk, and allowing the tools to operate more efficiently as a system.
