Norwegian Sea discovery more than doubles remaining Norne oil reserves

Equinor has, together with partners ENI and Petoro, completed the appraisal well on the Cape Vulture discovery from 2017. The well confirms a volume potential of 50 – 70 million recoverable barrels of oil. The discovery more than doubles the remaining oil reserves to be produced through the Norne field.

Originally planned to be shut down in 2014, the productive life of Norne has already been extended to 2036, which will generate substantial spin-offs.

“We are very pleased to have proven and appraised a new substantial oil discovery off the coast of Nordland. The appraisal well confirms a new play on the Nordland Ridge in the Norwegian Sea,” said Nick Ashton, Equinor’s senior Vice President, Exploration, Norway & UK.

“The discovery demonstrates the importance of our new exploration strategy. We intend to take new approaches and try out new and untested ideas to unlock the remaining commercial resources on the Norwegian continental shelf (NCS). This is in line with Equinor’s recently updated roadmap for the NCS, which aims to secure activity for many decades to come,” Ashton said.

“The Cape Vulture discovery also opens additional opportunities in the area. As an immediate consequence we will already next year drill a well on a similar prospect on the Nordland Ridge. We are also maturing other opportunities for the coming years that may help substantially increase the reserves around the Norne field,” Ashton added.

“Cape Vulture came as a gift in early 2017, and it confirmed that exciting subsurface secrets still remain to be unlocked in the Norne area,” said Siri Espedal Kindem, Equinor’s senior Vice President, Operations North.

“Our exploration people have been scrutinising the area for more than 40 years, and they are still cracking codes.”

Norne was the first field development off Nordland, marking the start of the Northern Norway oil era. The field came on stream in 1997. The remaining recoverable oil reserves in the fields producing through the Norne FPSO (in addition to the Norne field, this is Alve, Urd, Skuld and Marulk) are currently estimated at approximately 40 million barrels. There are also recoverable gas reserves corresponding to about 80 million boe still in place in these five fields.

The Cape Vulture discovery is located 7 kilometres northwest of the production vessel on the Norne field.

“Even in an early phase of development planning, this discovery will more than double the oil resources produced through the Norne infrastructure towards 2036, which we are very pleased to see. This is a great day for the Norwegian Sea and the industry in Northern Norway,” Kindem added.

“Exploration results like Cape Vulture are essential to Equinor. We will explore for this type of resources in the years ahead. Discoveries like this will be key to supporting our ambition to extend the lifespan of existing infrastructure,” Ashton concluded.

The exploration drilling in the Cape Vulture well (6608/10-17S) started in early December 2016. The drilling of the appraisal well, including side-tracks (6608/10-18, 6608/10-18B and 6608/10-18C), started in mid-July 2017. The wells were drilled in production license 128, a result of production license 128D awarded in the APA round (award in predefined areas) in 2015. The Cape Vulture Appraisal well was drilled by the Songa Encourage rig.
