Lundin Petroleum has announced that the Equinor operated 7132/2-2 well, Gjøkåsen Deep, did not discover hydrocarbons. Sandstones of varying quality were encountered in the late and early Triassic primary objectives, and a deeper extension to evaluate the underlying reservoir potential did not encounter reservoir rocks. The well was located in production licence PL857 and Lundin had assigned 428mmboe gross prospective resources to the prospect. The well followed on from the Gjøkåsen Shallow well (also in PL857) which had been estimated by Lundin to hold 768mmboe, but came up dry in February this year.

To date, only three wells (including Gjøkåsen Deep and Gjøkåsen Shallow), have been drilled in the frontier region which was opened up in 2016 with the award of three licences: PL 857,PL858 and PL859. Equinor will now move the West Hercules rig north to PL859 to drill the Korpfjell Deep prospect. The company previously drilled the Korpfjell prospect here in 2017, which proved a small non-commercial gas discovery. Korpfjell Deep is targeting 201mmboe in the Triassic and Permian, according to Lundin.

AkerBP is also planning to drill in the region at the Stangnestund prospect, although this has now been shifted into 2020. Originally planned for 2018, drilling was delayed when the company decided to take more time to plan the H2S well. Although this is a common occurrence in the oil industry, Norwegian operators have less experience of the toxic gas and AkerBP felt that more thorough planning was necessary. The prospect sits in PL 858 on the edge of the Fedynsky High, and will target an estimated preliminary gross volume of 30-190mmboe. However the majority of the Fedynsky High structure extends beyond the Norway-Russia maritime boundary so that if Stangnestund is successful, there could be significantly larger volumes in Russian waters. The Russian acreage is held by Rosneft and partnered by Eni (WI 33.33%).
