Libya and Tunisia open bid round for shared offshore area

Joint Oil Exploration, Exploitation and Petroleum Services Company (Joint Oil), a joint venture between Libya and Tunisia, has announced the opening of a new bid round on 7 September for development of the promising Zarat discovery and further exploration of the Joint Oil Block border acreage

Located in the prolific Gabes-Tripoli Basin of the central Mediterranean, this offshore acreage represents a premier opportunity for cross-border energy cooperation between Tunisia and Libya. Moyes & Co., a global upstream advisory firm, has been engaged to seek industry partners for two separate commercial packages:

• Exploration: Further exploration of the Joint Oil Block for new plays, leads, and prospects under an Exploration and Production Sharing Agreement (EPSA). The area concerned spans 3,000 sq km in water depth of 80-120m, with seismic data covering 6,500km of 2D & 1,900km of 3D. Wells: Zohra-1 (1976), El Amal South 1 (1999), Besmah-1 (2002), El Amal North 1 (2002), Zarat North 1 (2010). Surrounding producing fields: El Bouri, El Jurf and Bihr El Salam in Libya; Hasdrubal, Ashtart, Miskar & Didon in Tunisia.

• Development: Development of the Zarat Discovery — which straddles the Tunisia-Libya border— as a unitised oil and gas resource. This will be governed by a Development and Production Sharing Agreement (DPSA), Unitisation Agreement (UA), Unit Operating Agreement (UOA), and Operating Services Contract (OSC).

The bid round will close on 31 December 2026.

Credible companies with proven offshore exploration and development capability are invited to apply for access to the Virtual Data Room (VDR) managed by Moyes. Bids must be received by 8 January 2027. Winning bidders will be informed by 26 February 2027, with formal awards expected by 30 April 2027.

The bid round opportunity will be presented at the London Mediterranean, Middle East & Africa Scout Group (MMEA) on 9 September 2026 and at the World Energy Summit in London on 29-30 September 2026 where Joint Oil will also be present at a booth.

Strong potential

Joint Oil has highlighted the exceptional potential of the Joint Oil Block and the Zarat Discovery, strategically positioned along the southern margin of the Pelagian Basin within the geological extension of the Sabratha–Gabes Basin. 

The concession benefits from a highly strategic offshore location near several major producing fields across the Sabratha–Gabes Basin, including Al Jurf, Bahr Essalam, and Bouri offshore Libya, as well as Ashtart, Didon, and Miskar offshore Tunisia. This positioning enhances the project’s long-term value proposition through access to established regional infrastructure, operational synergies, and export pathways.

Bordered by active Libyan exploration zones and major offshore concessions, the Joint Oil Block and Zarat discovery further underscore the substantial untapped hydrocarbon potential of the shared Tunisian-Libyan offshore basin, reinforcing its attractiveness as a high-impact exploration and development opportunity for investors and strategic partners. Zarat is the largest discovery in offshore Tunisia since the Miskar discovery in 1975, and is the largest undeveloped field in offshore Tunisia. Contingent resources at Zarat attributable to the Joint Oil Block totals 158 mmboe.

Joint Oil is a joint venture between Libya and Tunisia through the national companies, the Tunisian Corporation of Petroleum Activities (ETAP) and Ola Energy Holdings Ltd. (OLA Energy). The company has managed hydrocarbon resources within the Tunisia-Libyan offshore acreage since 1988.
