Tunisia - Ashtart - OMV.

Found in 1971 by Elf Hydrocarbures Tunisie, Ashtart is Tunisia's first offshore field, located in the Gulf of Gabes 80 km south-east of Sfax. The discovery occurred at the same time as the coastal field Sidi el-Itayem was found by Total. Now the operator is a 50-50 JV of ETAP and OMV of Austria, which in June 2003 acquired the international E&P assets of Preussag of Germany including Ashtart and other blocks in Tunisia. The JV is called Societe de Recherche et d'Exploitation des Petroles en Tunisie (Serept). Ashtart at present is producing 10,500 b/d of sour 29.8? API crude oil, down from 11,000 b/d when OMV's acquisition took place, 14,000 b/d in 2002, 18,000 b/d in the first half of 1997, 19,000 b/d in the second half of 1996, 20,000 b/d in early 1996 and 30,000 b/d in 1987.

Production Services Network (PSN) of the US, formerly a unit of KBR of the US, in September 2008 got a two-year contract as part of a programme to upgrade existing offshore platforms and reverse Ashtart's decline and raise its production to 12,000 b/d by September 2010. PSN is managing the engineering, procurement and construction (EPC) contracts for upgrades on the platform topsides, pipelines and distributed control systems. The project aims to extend the field's lifespan and increase its reserves to more than 100m barrels.

Operators at Ashtart have changed hands four times since mid-1997, when Elf sold its Tunisian assets to Atlantic Richfield (Arco) of the US, which in 1999 was acquired by BP. These included Elf's 50% interest in Ashtart, then the second largest oilfield in Tunisia next to el-Borma, and shares in several blocks. Later Preussag acquired Ashtart and other assets.

In late March 2006, OMV made an oil and gas find in its 1,992 sq km Jenein-Sud block in the Ghadames Basin, 700 km south of Tunis. The first well, Warda-1, tested gas and oil. The well was spudded on Dec. 27, 2005, and encountered several oil and gas-bearing zones. During testing the well produced gas at a stable rate of 1,625 b/doe of gas and 1,500 b/d of 54? API oil. The well was later completed and suspended for further evaluation. A second well made similar finds in 2007. Each of OMV and ETAP holds 50% in this concession.

OMV first became active in Tunisia in the early 1970s. Membership in the group which discovered Halk el-Menzel was OMV's first ever foreign JV. The Preussag acquisition in 2003 brought OMV back to Tunisia by giving it control of seven small producing oilfields in the south-east of the country. The most prolific of these was Ashtart.

OMV in October 2008 announced the discovery and successful testing of condensate and gas in its Sourour-1 exploration well in the Jenein Sud permit in southern Tunisia. This was the fourth find in the permit since 2006 and highlighted the potential of this block. The well reached 4,013 m and encountered a total of 20 m net gas and condensate pay in several layers at depths ranging from 3,700 m to 3,950 m. Further exploration and appraisal were pursued later with plans to drilling additional wells. The cumulative flow rate of all layers of Sourour-1 amounted to 1,200 b/d of condensate and 58 MCF/d of gas. OMV and ETAP each holds a 50% interest in Jenein Sud, which covers 1,992 km2, 700 km south of Tunis.

OMV in mid-2008 announced discovery and successful testing of condensate and gas in its Ahlem-1 exploration well in Jenein Sud. The cumulative flow rate of all layers tested by the Ahlem-1 well amounted to 3,500 b/d of condensate and 120 MCF/d of gas.

OMV in February 2010 announced discovery and test of gas and condensate in Fella-1 exploration well in the Nawara production concession within the Jenein Sud block. A single 13 metre (gross thickness) zone was tested at the base of the Acacus Fm, resulting in a flow of 16 MCF/d of gas and 400 b/d of condensate. This is a 50-50 OMV-ETAP JV.

An agreement granting the Sidi Mansour permit was signed on June 8, 2009 by ETAP, OMV and UAE-based Thani Tunisia. This covered exploration, development and exploitation of petroleum deposits in an area of 6,592 sq km in the Gulf of Gabes. The work schedule was set for an initial three-year period and it consisted of carrying out a seismic operation and the drilling of an exploration well, with OMV and Thani Tunisia to spend $3m.
