EnQuest expands Decommissioning Operator role in the Greater Kittiwake Area

EnQuest Heather Limited ('EnQuest'), owner and operator of the Greater Kittiwake Area ('GKA')

fields, along with Shell U.K. Limited ('Shell') and Dana Petroleum (E&P) Limited ('Dana'), are

responsible for the decommissioning of the GKA fields.

Recognising EnQuest's ability to deliver safe results, market-leading decommissioning

performance and cost and schedule efficiencies, the joint venture has appointed EnQuest to

continue as GKA operator for the full decommissioning scope with Shell transferring its

decommissioning management role to EnQuest. Note: Shell had retained operator responsibility

for decommissioning the Kittiwake platform and the Mallard field, a subsea tie-back to the

Kittiwake platform, when it divested the GKA fields.

The GKA infrastructure is expected to continue production into the late 2020's with EnQuest

proactively planning for a managed decommissioning programme post cessation of production.

EnQuest is delivering on its strategic objective to be the preferred decommissioning operator in

the North Sea. EnQuest has demonstrated market leading decommissioning operator

performance through execution of complex decommissioning projects, including the removal of

the EnQuest Producer and Northern Producer facilities and the ongoing and extensive well plug

and abandonment ('P&A') scopes at the Thistle and Heather fields at 40% below benchmark

costs. EnQuest is on track to complete the P&A of 77 wells, which represents 60% of the

EnQuest operated suspended and shut-in wells, within 5 years of cessation of production.

John Allan, EnQuest Decommissioning Director, said "this is a great vote of confidence in

EnQuest by our GKA partners Shell and Dana. It reflects our strong track record of safe, efficient

and successful execution of complex decommissioning scopes which is an important part of our

company growth strategy. "
