Lundin spuds Gohta appraisal well in Barents Sea

Lundin Norway AS, a subsidiary of Lundin Petroleum AB, has spud appraisal well 7120/1-4s in PL 492 near the Gohta discovery in the Barents Sea.

The well’s objective is to test the reservoir properties and hydrocarbon potential of the Permian carbonates in the Gohta karst Roye formation and the overlying Kobbe formation sandstones.

The well will be drilled using the Island Innovator drilling rig over a period of 65 days. Planned total depth is 2,930 m below mean sea level.

Gotha discovery well 7120/1-3, about 5.7 km southeast of 7120/1-4s, was completed in October 2013, finding a 25-m gross gas column above a 75-m gross oil column in karstified and dolomitized limestone (OGJ Online, Oct. 2, 2013). The well production tested 4,300 b/d through a 44/64-in. choke.

Preliminary evaluation of the gross recoverable oil and gas resources from the Gohta discovery is estimated at 105-235 million boe, of which oil comprises 60-145 million bbl and gas about 275-545 bcf.

“The discovery has proved the Permian carbonate play concept in the area, and, as well as delineating the discovery, we will now look to drill similar exploration prospects in adjoining licenses where we have a significant acreage position,” said Ashley Heppenstall, Lundin president and chief executive officer, after 7120/1-3 completion.

The company said the well represented the first successful test of Permian carbonate reservoirs on the Norwegian continental shelf.

Lundin Norway is PL 492 operator with 40% working interest. Partners are DNO ASA 40% and Noreco Norway AS 20%.
