Repsol SA encountered gas at a depth of 1,307 m in the Tan Emellel Sud-Ouest-2 (TESO-2) exploration well of the Sud-Est Illizi block in southeast Algeria, yielding a flow rate of 175,000 cu m/day and 90 b/d of condensate on a 32/64-in. choke.
Four more wells are planned to appraise previous discoveries within the block. In 2012 the Tihalatine South-1 well—the first of a five-well exploratory program—tested at a rate of 3.7 MMcfd at 1,073 m (OGJ Online, Nov. 9, 2012).
Repsol operates the block with 52.5% interest. Partners are Enel SPA 27.5% and GDF-Suez 20%. Algeria’s state-owned Sonatrach will hold 51% interest in the development and production phases, with the existing members maintaining their existing proportions in the remaining 49%.
Repsol’s activities in Algeria, where the company produces 8,000 boe/d, comprise the Tin Fouye Tabankort production project, Reggane Nord development project, and Sud-Est Illizi and Boughezoul exploration projects. Sud-Est Illizi was awarded in December 2009 and Boughezoul in October 2014.
