Cairn Energy has made an oil discovery at the 9/14a-17B well and associated side-track on the Agar-Plantain Prospect in the U.K. North Sea, the company said on Nov. 15.

The company also entered a farm out agreement for a 40% non-operated interest of the Chimera prospect in the U.K. North Sea.

The next well in Cairn’s exploration program will be Presto (formerly Stjerneskudd) on PL885 in the Norwegian North Sea.

Based on preliminary analysis, the operator estimates the Agar-Plantain discovery holds recoverable resources of 15 million barrels of oil equivalent (MMboe) to 50 MMboe.

The discovery is located in close proximity to existing infrastructure, located 12 km (7 miles) from the Beryl Bravo facility to the southwest and 14 km (8 miles) from the Alvheim FPSO to the southeast.

Further evaluation of development options to establish commerciality will be undertaken by the joint venture partners in the coming months.

The initial 9/14a-17B well on the Agar-Plantain Prospect was drilled safely to the target depth and encountered excellent quality oil and water bearing sands. The wellbore delineated the eastern extent of the hydrocarbon discovery and the partners agreed to drill the contingent side -track to further appraise the discovery. The Agar side-track encountered a 20 m (65 ft) gross interval of very high quality oil bearing sands.

Cairn has an option to take over operatorship with respect to future activity on the Agar-Plantain project. The Agar-Plantain well is currently being plugged and abandoned by operator Azinor Catalyst. Working interests in the well are: Azinor Catalyst (operator) 25%, Cairn 50% and Faroe Petroleum 25%.

The commitment exploration well on license P2184 in the U.K. North Sea targeting the Ekland prospect (Cairn operator, 45% working interest) failed to encounter commercial hydrocarbons and has been plugged and abandoned.

Cairn has entered into a farm out agreement for a 40% non-operated interest in License P2312 (Cairn operator, 100% working interest) containing the Chimera prospect targeting 154 gross MMboe mean resource (92 MMboe net) in the U.K. North Sea with plans to drill a well in H2 2019. The farm out agreement is conditional upon regulatory consent.

The next well in Cairn’s exploration program will be Presto (formerly Stjerneskudd) (Cairn 30% WI) on PL885 in the Norwegian North Sea, targeting 160 gross MMboe mean resource (48 MMboe net) with standalone potential and significant follow on potential with success. The well is expected to spud in late December 2018 by operator Equinor.
