The Benbecula Field is located 90 km north-west of the Scottish Outer Hebrides. Siccar Point acquired a 60% operated interest in the field and the surrounding P.2138 exploration licence from the takeover of OMV (U.K.) in January 2017.
Benbecula was discovered in 2000. It is a material gas discovery in Tertiary Vaila sandstones that requires more discoveries in the immediate vicinity to be commercial.
The P.2138 licence is located on the eastern edge of the Rockall Basin. The Pre-Cambrian West Lewis Ridge lies directly to the east of the licence, along the edge of which are stacked sedimentary sequences which form a north-south trend of leads and prospects. This includes the Benbecula discovery, which, along with the 164/28-1A exploration well which contains good oil shows in Tertiary Vaila sands, indicate that there is an active hydrocarbon system in the area. The oil is comparable to the prolific Upper Jurassic Kimmeridge Clay Formation oils in the North Sea and West Shetland Basin. Mapping of the existing 2D seismic data shows prospectivity in both intra-lava type Tertiary plays analogous to Rosebank, and also in older Tertiary deep marine mass flow sands as found in Schiehallion. Two material prospects, both expected to be oil-bearing, have been mapped along trend to the 164/28-1A well.
Play and prospect assessment is ongoing.
The P.2139 licence is located on the far western side of the Rockall Basin 350 km north-west of the Scottish Outer Hebrides and close to Rockall. Siccar Point acquired a 100% operated interest in this licence from the takeover of OMV (U.K.) in January 2017.
This large licence contains significant 4-way closures as mapped from the existing 2-D seismic data. Potential reservoirs are in both the Tertiary and older formations. The P.2139 licence lies at the western edge of the West Rockall Basin. A proprietary sea-surface oil slick survey over the area has indicated a high density of natural oil slicks which are believed to be seeping from Tertiary lava flows at their intersection with the sea bed: this is strong evidence for an active oil- generating basin in the area. There are numerous shallow basalt lava sequences in the area which make the seismic imaging difficult with the current 2D datasets. Reprocessing of the existing 2D and modern 3D seismic would improve the ability to image the sub-basalt sequences and hence firm-up the prospects.
Regional assessment of this area is ongoing.
