The Stena Don, a semi-submersible and fifth generation drilling rig, has been contracted to start operations in the summer drilling season (June-October) on Cairn’s Disko West acreage in Greenland.

The Stena Don will work alongside the previously announced Stena Forth on Cairn’s Greenland exploration drilling programme subject to all required government approvals.

Earlier, Cairn secured the first drilling rig Stena Forth, a sixth generation drill ship, which has been contracted to start operations in the summer drilling season (June-October) on Cairn’s Disko West acreage in Greenland.

Cairn had reached agreement with Hess and Stena Drilling to take an assignment of the Stena Forth for a period of approximately six months.

Mike Watts, deputy chief executive of Cairn Energy, said: “Contracting a second drilling rig for Greenland has further increased Cairn’s operational capability and flexibility. We can now look forward to drilling up to four exploration wells in the undrilled Baffin Bay Basin offshore Disko West later this year.

“The acceleration of this exploration activity off the west coast also provides us with flexibility to include the previously unmapped and undrilled basins off the southern coast of Greenland in our planned future drilling programmes.”
