3D Seismic Survey commences over the Barryroe Oilfield in the North Celtic Sea, offshore Ireland

Lansdowne Oil & Gas, ("Lansdowne") welcomes the announcement today that Providence Resources plc ("Providence"), as Operator, has commenced the 3D seismic acquisition project in the North Celtic Sea, offshore Ireland, using a vessel supplied by Polarcus Limited.

The survey, which is expected to be completed within 2 weeks, forms part of the planned pre-development drilling programme on the Barryroe oil discovery ("Barryroe"), in which Lansdowne holds a 20% interest, and is designed to progress Barryroe to first oil. The drilling of Barryroe is scheduled to commence late this summer, with the GSF Arctic III semi -submersible rig already contracted for the drilling programme. The partners believe that modern 3D seismic data, in tandem with modern well completions in the current high oil price environment, will be key components to unlocking value at Barryroe.

Upon completion of the Barryroe 3D seismic survey, Lansdowne will take over the Polarcus vessel for the acquisition of 3D seismic over the Rosscarbery, Amergin and Midleton prospects in the North Celtic Sea, covering an aggregate area of approximately 300 sq km.
