Equinor has found more oil and gas at the Tyrihans field in the Norwegian Sea, proving petroleum in lower-mid Jurassic reservoir rocks, the company said April 21.
The discovery, deemed commercial by the Norwegian major, is believed to hold estimated recoverable resources of between 19 and 26 million barrels of oil equivalent. The Tyrihans field is located about 25 km southeast of the Åsgard field.
“It is encouraging to prove new resources that can extend the life of producing fields in the Norwegian Sea,” said Nick Ashton, Equinor’s senior vice president for exploration on the Norwegian Continental Shelf.
Drilled from subsea template A at Tyrihans North in production license 073 by the Transocean Norge rig, exploration well 6407/1-A-3 BH hit a 43-m gas column and a 15-m oil column in the Ile Formation. This included, Equinor said, about 76 m of moderate to good reservoir quality sandstone. Good quality water-bearing reservoir was also hit in the Tilje Formation.
The well was drilled to a vertical depth of 3,998 m below sea level and a measured depth of 5,332 m, the company said. It was completed in 299 m of water.
“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,” Ashton said.
Equinor’s partners are Total E&P Norge AS and Vår Energi AS.
CEO Vicki Hollub said May 11 she was concerned about the possibility of a federal moratorium on new oil and gas leases going forward.
U.S. oil producers have been gradually increasing drilling activity as oil prices have rebounded but output growth has been muted as investors pressure companies to rein in spending and focus on returns.
Schlumberger and NOV have entered a partnership on May 10 to accelerate automated drilling solutions adoption by oil and gas operators and drilling contractors.
