"We are pleased to have commenced drilling at the Nunya prospect offshore Ghana where we are looking to test the regionally proven Upper Cretaceous play that has yielded successful results elsewhere along the West Africa Transform Margin. Having made a successful start to our 2012 exploration drilling campaign with the Okoro East discovery, and with the JS-2 exploration well drilling ahead in the Kurdistan region of Iraq, the Company is firmly engaged in its most active phase of exploration activity to date with multiple wells planned across Afren's core areas, each of which has the potential to materially increase the Company's discovered reserves base."
