Faroe Petroleum, the independent oil and gas company focusing principally on exploration, appraisal and production opportunities in Norway and the UK, has announced a successful result with the Agar/Plantain exploration and appraisal well in licence P1763 (Faroe 25% of Agar/Plantain, 12.5% of the wider licence), located in the UK Continental Shelf (UKCS).

Faroe estimates that the recoverable resources in Agar are between 15 and 50 million barrels oil equivalent (between 3.8 and 12.5 mmboe net to Faroe). Reservoir encountered close to prognosis: 20 metres gross hydrocarbon-bearing reservoir section with excellent reservoir quality and high net to gross ratio. Further evaluation of development options to establish commerciality will be undertaken in coming months.

The initial wellbore of the exploration well 09/14a-17B targeted the Plantain prospect and was drilled to a total depth of 2,254 metres MD. The well encountered a thin oil column in a high-quality sandstone reservoir. Based on this promising result, the partnership elected to drill a sidetrack 09/14a-17BZ up-dip to appraise the 2014 Agar oil discovery.

The Agar sidetrack successfully encountered the Upper Frigg Formation at 1,763 metres MD and penetrated a gross reservoir zone of 20 metres, with a high net to gross ratio confirmed by log and pressure analysis, and an average porosity of approximately 30%. No oil-water contact was observed in the well. All data from the discovery is being assimilated and a future work programme on the licence is now being considered by the joint venture partners. The sidetrack well 09/14a-17BZ was drilled to a total depth of 1,962 metres MD.

In the Plantain prospect, at a depth of 2,066 metres MD, the well encountered approximately 27 metres TVD of high-quality net reservoir sandstones of the Eocene Lower Frigg Formation. Logging-while-drilling and pressure analysis indicates a thin net oil pay zone with a significant underlying zone of residual hydrocarbons.

The Agar/Plantain discovery is located approximately 12 kilometres from the Apache-operated Beryl Bravo facility to the south west, and the Alvheim FPSO is located approximately 14 kilometres to the southeast. These facilities both offer potential for development of the Agar discovery.

The well was drilled by the Transocean Leader semi-submersible drilling rig and will now be plugged and abandoned as planned. The Agar/Plantain wells are operated by Azinor Catalyst (25%) with partners Cairn (50%) and Faroe (25%). Licence P1763 is operated by Apache Beryl Limited (50%), with partners Cairn (25%), Faroe (12.5%) and Azinor Catalyst (12.5%).

Graham Stewart, Chief Executive of Faroe Petroleum, comments, “We are pleased to announce a very promising discovery in the Agar Plantain prospects. This is our first exploration well in the UK since 2013 and this together with the award of the exploration licence on the exciting Edinburgh prospect earlier this year marks a return of focus to the UKCS which offers significant value potential, especially with our existing tax losses in the UK.”

“The Company’s exploration programme will continue over the remainder of the year with two further committed exploration wells in Norway: the Brasse East (Faroe-operated) and Cassidy wells,” Stewart adds.
