ABERDEEN, Scotland — BiSN, a supplier of downhole sealing solutions and technology to the oil and gas industry, has been awarded a key contract by a major oil and gas operator in the North Sea. The contract requires BiSN to use its Wel-lok alloy barrier technology to safely and efficiently plug and abandon (P&A) oil and gas wells in the North Sea.
BiSN signed a three-year contract, which features two one-year extensions, to provide this operator with Wel-lok alloy plugs for its ongoing offshore UK P&A campaign.
The technology provides a permanent well-barrier and gas-tight seal in single and multiple annuli.
The company says the Wel-lok alloy plug barrier technology ensures a permanent plugging and abandonment of oil and gas wells so they are securely and reliably sealed, vastly reducing corporate liability and potential environmental impact.
BiSN's largest operation utilizing Wel-lok alloy plug barrier technology in the region featured a 30-well campaign carried out on Valhall Field on behalf of Aker BP, which was completed in 2021. The technology is now used on 30 wells on the Valhall Field, providing safer, permanent well plugging, BiSN said.
