Kerloch flows oil for Dana
Offshore staff
ABERDEEN, UK --Dana Petroleum has discovered oil in the Kerloch structure in the northern North Sea.
A semisubmersible drilled well 211/22a-10 to TD of 12,282 ft (3,743 m), encountering a full Brent reservoir sequence, with an oil column of around 116 ft (35 m) in the Ness formation. The gas-oil ratio was in line with other discoveries in this region.
Dana designed the well as a slim-hole 'finder' type, with a long open hole section drilled to TD. The company and its partners have decided against conducting a drillstem test, as this could add significant cost and technical risk to the program.
Numerous tests have been performed on the Brent sands in nearby wells, including Antrim's East Causeway well in an adjacent block last year. This flowed stabilized oil from the Ness formation at up to 7,500 b/d.
The Kerloch well has been suspended for potential re-entry and future use. The rig will move to the central UK sector for an exploratory well on Morgan, a Palaeocene oil prospect close to the Greater Kittiwake Area complex.
