The new Cat J jackup rig Askeladden began drilling at Gullfaks area on March 26, with the purpose of offering new manufacturing from previous wells and exploring to create new worth.

Askeladden has been purchased by the Gullfaks licence to hold out manufacturing and exploration drilling on Gullfaks Satellites. For a number of months the rig needed to wait on climate, each on its manner from the yard in South Korea and when it met the Norwegian winter climate. It arrived on the area on Feb. 19 and, on March 5, the legs have been firmly positioned on the seabed at its closing location by the subsea template.


“Safety is our high precedence – we won’t begin any operations earlier than we’re assured that they are often carried out safely. We have spent the ready time on maturing new prospects and coaching personnel,” says Gunnar Nakken, head of the operations west cluster in Statoil.

“Gullfaks has been, and can proceed to be, a promising space, and extra exploration wells will probably be drilled through the subsequent years, together with manufacturing drilling. We are planning a protracted area life past 2030 on Gullfaks, and Askeladden will probably be key to take care of excessive worth creation on the sector,” he says.

Plugging first

Plugging of two wells begins now earlier than they will reuse the wells, so-called slot restoration, and drill to new nicely targets. The second nicely could have a sidetrack to the Rimfaks Lomvi prospect at four,200-m depth to discover for brand spanking new hydrocarbon deposits.

So far, 11 wells are deliberate for the primary two years of operation, nevertheless, the rig is to satisfy a long-term want. New plans reaching past 2020 are constantly being developed. The KCA Deutag drilling contractor was awarded an eight-year contract.

Designed for effectivity

“This is a really thrilling rig which is nicely ready for a digitalized future, and may begin utilizing nearly any new expertise. It has a subsea blowout preventer, which isn’t widespread on jackup rigs. That makes it a superb working platform for improved work effectivity, and reduces our want to attend on climate. Our problem will probably be to make the most of the climate home windows correctly, and keep away from shifting the rig within the winter season,” mentioned Carlos Kauffmann, drilling superintendent for the Cat J rig Askeladden.

On Feb. 25, the sister rig Cat J Askepott will begin drilling on a brand new area, Oseberg Vestflanken 2. Consequently, the Gullfaks start-up marks that each newbuilds known as the “tremendous rigs” at the moment are in operation for Statoil and its companions.
