ABERDEEN, UK – EV Offshore has completed subsea well inspection services for Nexen Petroleum UK on the Scott field in the North Sea.

Following drilling of an 8.5-in (22-cm) section, the Vetco wear bushing was pulled from the multi-bowl. Vertical gouging was evident on the outside diameter of the wear bushing, giving rise to concerns that a foreign body, or a piece of swarf, had become trapped between the wear bushing and multi-bowl. This fueled further suspicion that the tubing hanger seal areas may have been damaged, according to EV.

EV Offshore inspected the tubing hanger seal areas with its RT 120, drillpipe-deployed camera system. Based on the images obtained, Nexen engineers decided that the marking was superficial, and would not affect the integrity of the tubing hanger seal. Operations resumed and Nexen engineers continued to run the completion. Finally, the tubing hanger was landed and successfully tested.
