As part of the deal, Kosmos will buy an 85% interest and take up the operatorship of both licences, alongside incurring 100% of the costs of the first exploration well on each block.
The company will also fully fund the cost of a 3D seismic programme on each licence and pay 85% of the costs incurred by Europa to date.
The first exploration wells on LO 11/7 and LO 11/8 have investment caps of $90m and $110m, respectively, while Kosmos will share 85% of the excess costs of the investment cap, with the remaining coming from Europa.
Both LO 11/7 and LO 11/8 cover an area of about 1,000km² each in the prospective South Porcupine basin, while the licences have been mapped using existing 2D seismic data and are currently undrilled.
Europa has identified two previously unknown prospects in the Lower Cretaceous stratigraphic play - Mullen in LO 11/7 and Kiernan in LO 11/8.
Europa CEO, Hugh Mackay, said Kosmos is an experienced operator in frontier basins and pioneered the Cretaceous stratigraphic play that lead to a major exploration success in the Atlantic margin basins.
"The farm-in provides recognition of the substantial potential value lying in our Irish exploration prospects. The work programme associated with the farm-in has the potential to deliver significant value realisation," Mackay added.
"Europa's retained 15% interest exposes the company to substantial upside in the event of drilling success at either or both of these prospects at a much reduced risk and cost to our shareholders.
"We understand that the Eirik Raude rig is in Irish waters to drill Exxon's Dunquin well. An exciting new chapter in the exploration of Ireland is starting and we are delighted to be part of it."
The closing of the farm-in agreement is subject to approval from the Irish Government.
