The Chouchet El Atrous-1 (Cat-1) well, drilled by Mazarine Energy Tunisia BV in the Zaafrane permit in central Tunisia, has discovered two net oil-bearing reservoirs with combined 38-m net pay. Primary objectives of the Cat-1 were to test the Ordovician El Hamra and El Atchane formations. Each zone has confirmed 19-m net pay.
On test, the Cat-1 flowed 4,300 bo/d and 395,000 cu m/day of natural gas. The Cat-1 is the first of a two-well campaign, the company said. Compagnie Tunisienne de Forage drilled the Cat-1 well, which reached a total depth of 3,950 m. The DGH-1 well will follow.
The Zaafrane permit spans an area of 5,168 sq km in central Tunisia. Mazarine Energy is the operator of the permit, with state-owned Enterprise Tunisienne d’Activites Petrolieres (ETAP) and Medex Petroleum (Tunisia) Ltd. as partners.
