As of March 2019, Primoil is farming out a stake in its El Kef permit, onshore Diapir Zone, north-western Tunisia. The company is offering a 40% interest in the block in exchange for a USD 14 million investment.  Primoil and former partner Oil Search (Tunisia) Ltd were awarded the permit in May 2008. In November 2012, Primoil was granted a two-year validity extension of the first exploration period and in August 2015, the company entered into the second exploration period.  Primoil holds a 50% interest in the permit. The Tunisian state company Etap holds a 50% carried interest. El Kef covers 2,836 sq km.  Commitments of the first exploration period were the drilling of one exploration well to a depth of 3,000 m, the acquisition of 200 km of 2D seismic or 3D equivalent and the reprocessing of 600 km of existing 2D seismic data for a total expenditure of USD 5 million.Â  The seismic acquisition was completed in 2010.   Primoil has drilled one well in its permit in 2014: Secca Veneria 1 (SCV-1). The well had a planned TD of around 3,500 m and targeted reservoirs in the Lower Cretaceous. Industry sources indicated that in November 2017 Primoil re-entered SCV-1. The company intended to side-track the well for testing as during the initial drilling technical difficulties prevented a test. It is assumed that operations were completed in the second quarter of 2018 and that the test was not a success.  The Le Kef block is located in a geologically complex area renowned for numerous oil seeps. Cretaceous and Tertiary reservoirs are present and form trap geometries as a result of folding, thrusting and Triassic salt movement. Mature Cretaceous and Tertiary source rocks are present to charge the reservoirs with oil.
