LONDONDeltic Energy has identified three prospects on license P2428 in the UK southern North Sea, which was awarded under the 30th Offshore Licensing Round.

Cupertino is a four-way dip closed intra-Carboniferous prospect in the Scremerston formation, a proven producing reservoir at the Breagh gas field and at the Crosgan discovery, 40 km (25 mi) to the west.

It extends more than 68 sq km (26 sq mi) with the structural crest at 3,500 m (11,483 ft) TVDSS, with a potential hydrocarbon column height of 220 m (722 ft). Cupertino could hold between 705 bcf and 1,615 bcf of gas.

Richmond is primarily a Rotliegend Leman sandstone, three-way dip and fault sealed structure with similarities to Cygnus 50 km (31 mi) to the east, and currently the UK’s largest producing gas field. Prospective resources range from 494-1,152 bcf.

Plymouth is a previously unrecognized Zechstein Reef in a similar paleogeographic setting to the Pensacola prospect on the company’s license P2252, which Shell farmed into in 2019.

Hydrocarbons could be sourced from the early Carboniferous basin to the south and are likely to be primarily gas, similar to that produced from Cygnus. Deltic’s resource estimates range from 56 bcf to 1,990 bcf.

Plymouth also extends into an unlicensed area to the east of the P2428 boundary which is subject to development planning for wind farms. This could present opportunities for electrification of offshore facilities, gas to wire-based developments or offshore hydrogen production.

However, new 3D seismic data will have to be acquired over the area to de-risk these prospects and leads prior to drilling.
