The awards have been offered to 11 companies, including AzEire Petroleum, Capricorn Ireland, Europa Oil and Gas, Faroe Petroleum, Petrel Resources, Ratio Petroleum, and Scotia Oil and Gas.
All these companies will serve as operators. Theseus will partner Predator, and Sosina Exploration which will partner Providence.

Petrel Resources director David Horgan said: "These awards are an endorsement of the strong technical work of Petrel that supported our bids.
"Major and mid-cap oil companies have also taken acreage, which validates our long-standing belief that the Porcupine Basin is underexplored and has reserve potential."
