Shell Resumes Production from Shearwater Field

Shell said that the Shearwater Field located in the U.K. North Sea has resumed production, which had been shut in since the end of March.

An extensive investigation revealed a pressure change in one of Shearwater's wells, which forced Shell to shut the field down, was caused by a leaky seal, which allowed a small volume of non-volatile fluid to move between compartments in the well. It was determined that the seal was damaged during installation. A pumping vessel was used to pump high-gravity fluid into the well, which eliminated the pressure and then rig-based repairs were carried out, according to a Shell spokesperson. Shearwater has a maximum output of 370 million standard cubic feet of gas and 80,000 barrels of oil a day.
