At the start of April, Norwegian energy giant Equinor, together with partners French based Total and Norwegian owned Vår Energi, announced the discovery of oil and gas in the Tyrihans field in the Norwegian Sea. According to Equinor’s press release, it is estimated that there could be between 19 and 26 million barrels of oil equivalent in these lower-mid Jurassic reservoir rocks (Ile and Tilje formations).

Nick Ashton, Equinor’s senior VP for exploration on the Norwegian continental shelf noted “It is encouraging to prove new resources that can extend the life of producing fields in the Norwegian Sea”.

The exploratory well was drilled by Transocean Norge drilling rig. Equinor reported the result from exploration well 6407/1-A-3 BH in production licence 073, which was drilled from subsea template A at Tyrihans North. The Tyrihans field is in the middle of the Norwegian Sea, some 25 kilometres south-east of the Åsgard field and 220 kilometres north-west of Trondheim. The licensees consider the discovery commercial and intend to start production immediately.

“Thanks to the location we are able to put the discovery on stream over the Tyrihans field immediately, which will both ensure good profitability and low CO2 emissions from production,” says Ashton.
