Aberdeen-based well integrity technology services provider Unity has secured a three-year contract extension from an undisclosed UK North Sea operator.

The technology services firm also has two additional one-year extension options.

Unity said that the contract extension would see the company continue to serve three northern North Sea platforms.

The company did not disclose the value of the contract but noted that the extension was worth ‘an annual six-figure sum’.

Unity CEO Gary Smart said: “Unity’s flexible and adaptable approach will continue to support our client’s requirements as it moves forward into a phase of decommissioning with its assets.

“We hold contracts with leading operators to provide services on over one thousand wells and have built a successful track record of decommissioning support work in the UKCS and Europe.

“Projects have included well inspection, plug setting, isolation verification, on-site machining and the safe removal of Xmas trees and tubing hangers. Unity’s technology solutions such as our Surface Intervention System may also be used to enhance efficiency.”

Under the contract extensions, Unity will provide well integrity, wellhead maintenance, as well as associated support services for the three platforms. Surface wellhead and Christmas tree integrity services, the supply of personnel, equipment and technology, including Unity’s suite of retrofittable QV wellhead parts, are also included.

Furthermore, Unity will support abandonment and decommissioning work on two of the North Sea platforms.

In June last year, Unity developed a new technology to pressure test suspended mudline wells from a vessel before plugging and abandoning (P&A) activity for improved safety and cost savings.
