Lundin completes Gohta appraisal well in Barents Sea

Lundin Norway AS, a wholly owned unit of Lundin Petroleum AB, Stockholm, has completed drilling its Gohta appraisal well 7120/1-5 in PL492 in the southern Barents Sea.

Lundin Norway AS, a wholly owned unit of Lundin Petroleum AB, Stockholm, has completed drilling its Gohta appraisal well 7120/1-5 in PL492 in the southern Barents Sea.

The Gohta discovery, made in Permian carbonate reservoir rocks with well 7120/1-3 drilled in 2013, was estimated to contain gross contingent resources of 91-184 million boe prior to the drilling of well 7120/1-5.

The appraisal well was drilled 4 km north of the original discovery well and was the second appraisal well on the Gohta discovery. The main objective of the well was to delineate the northeastern segment of the discovery, Lundin said. The well encountered a 300 m gross sequence of Permian-age carbonates with poor reservoir quality. Hydrocarbon shows were observed but no pressure gradients could be established, the firm said. The well will be permanently plugged. Extensive data acquisition and conventional coring was carried out in the reservoir.

This fourth well in the 2016-17 drilling campaign on the Loppa High was drilled to a total depth of 2,502 m below mean sea level and in 344 m of water.

Gohta is considered a satellite opportunity to the larger adjacent Alta discovery. This result has no impact on Lundin Norway's appraisal and conceptual development plans for Alta, which includes an appraisal well that will be spudded imminently and an extended well test planned for 2018, Lundin said.

Lundin Norway is operator of PL492 and holds a 40% working interest in the license. Aker BP is partner with a 60% working interest.

The well was drilled using Ocean Rig UDW Inc.’s Leiv Eiriksson semisubmersible drilling rig. Once the rig has plugged the 7120/1-5 well, it will move 15 km northeast to spud the Alta appraisal well 7220/11-4 in PL609 where Lundin Norway also is operator.
