Equinor Energy AS and partners plan to immediately begin production of an oil and gas discovery considered commercial in a new segment belonging to Tyrihans field in Norwegian Sea production license 073. Recoverable resources are estimated at 3.0-4.2 million standard cu m of recoverable oil equivalent (19–26 MMboe).
Tyrihans field lies 25 km southeast of Åsgard field and 220 km northwest of Trondheim.
Well 6407/1-A-3 BH, the sixth exploration well on the field and the fifth in the license, was drilled by the Transocean Norge drilling rig from subsea template A at Tyrihans North in 288 m of water to a vertical depth of 3,998 m and a measured depth of 5,332 m subsea. The well was completed in the Åre formation from the lower Jurassic period.
The purpose of the well was to prove petroleum in lower-mid Jurassic reservoir rocks (Ile and Tilje formations).
The well struck a gas column of about 43 m and an oil column of about 15 m in the Ile formation, including about 76 m of moderate to good reservoir quality sandstone. Moderate to good quality water-bearing reservoir was struck in the Tilje formation.
Data acquisition and sampling were carried out. The well was not formation tested. The pilot will be permanently plugged.
The drilling rig will now continue drilling producer well 6407/1-A-3 CH on Tyrihans field.
Equinor is operator of the license with 58.767%. Partners are Total E&P Norge AS (29.143%) and Vår Energi AS (12.09%).
