In 2004, Petroceltic acquired a licence called 'Isarene' in the Illizi basin of Algeria.[1] In 2006, the company started the first of its exploration wells in Algeria and over the next few years explored the Isarene field with 3D seismic and 13 wells which ultimately led to the discovery and appraisal of the Ain Tsila gas condensate field and the submission of the Field Development Plan. The Ain Tsila field is currently under development. Partners in the field include Sonatrach (the Algerian state energy company) and Enel, the Italian utility.[2]
