DNO Norge has received the consent to use the Borgland Dolphin semi-submersible drilling rig for a permanent plugging of wells on the Oselvar field offshore Norway.

Consent from the Norwegian offshore safety watchdog, the Petroleum Safety Authority (PSA), allows DNO Norge to permanently plug wells A-1 H, A-2 H, and A-3 HT2 on the offshore field.

The Oselvar field is located in the Production licence 274 in the southern part of the Norwegian sector in the North Sea, 20km south-west of the Ula field.

Production from the field was sent to the Ula platform for gas separation and injection in the host field reservoir whereas the liquid was sent to Teeside via Ekofisk.

Situated at a water depth of 70m, the field commenced production in 2012 and was shut down in May 2018, due to its inefficiency to live up to its initial expectations.

Decommissioning of the field is planned to be completed by the end of 2022, as per the formal disposal resolution.

DNO operates the production licence with a 55% stake while CapeOmega owns the remaining 45% interest.

In January, the PSA gave its consent to Chrysaor and Aker BP to use rigs for their respective drilling projects offshore Norway.

Aker BP secured consent to use the Maersk Integrator ultra-harsh environment jack-up rig for production drilling on the Tambar field located in the southern part of the Norwegian sector in the North Sea.

Chrysaor Norge secured consent to use a semi-submersible drilling rig for exploration drilling of wells 15/12-25 and 15/12-26 located in production licence 973 in the North Sea.
