Eni strikes two adjacent gas structures off Libya with over 1 tcf of gas in place, paving the way for fast-track development via existing offshore infrastructure
Back-to-Back Strikes in Libyan Waters
The Italian major’s exploration campaign targeted two adjacent geological structures: Bahr Essalam South 2 (BESS 2)and Bahr Essalam South 3 (BESS 3), drilled through the B2-16/4 and C1-16/4 wells respectively. Both sit approximately 85 kilometers off the Libyan coast in roughly 650 feet of water — and just 16 kilometers south of the Bahr Essalam gas field, the largest producing offshore field in the country.
Gas-bearing intervals were encountered within the Metlaoui Formation, recognized as the main productive reservoir in the area. A well test carried out on the first well has already confirmed productive capacity, moving the finds from geological inference to commercial reality.
Infrastructure Proximity Changes the Math
What elevates these discoveries beyond their raw volume is the development equation. Their proximity to the Bahr Essalam field — in continuous operation since 2005 — means both BESS 2 and BESS 3 can be developed through tie-back to existing offshore infrastructure, bypassing the capital-intensive, time-consuming process of building standalone production facilities.
That matters enormously in Libya, a country where the gap between discovery and first gas has historically been measured in years rather than months. Eni’s ability to leverage its own infrastructure shortens that gap considerably.
Italy’s Supply Chain Calculus
Commercially, the discoveries reinforce Italy’s long-standing strategy of anchoring its natural gas supply to North African producers. Gas from the new fields will supply the Libyan domestic market and be exported to Italy — a bilateral energy relationship that Eni has been deepening for decades.
The company’s equity production in Libya reached approximately 162,000 barrels of oil equivalent per day in 2025. Three development projects are currently under execution, two of which are expected to reach startup this year.
A Continent Still Rethinking Its Gas Map
Europe’s push to reduce dependence on Russian pipeline gas has elevated North African producers to a central role in Mediterranean energy planning. Libya, despite persistent political instability, consistently ranks among the most promising exploration frontiers in the region.
Eni’s latest find comes roughly a month after the company announced a gas and condensate discovery offshore Côte d’Ivoire — part of a broader exploration offensive the major has been running across the African continent.
The Waterline Report
For decision-makers in the offshore energy sector, the Libya discoveries carry a message that transcends their headline volume. The real competitive advantage here is not the 1 tcf figure — it is the tie-back model. In a global environment where greenfield development economics are under scrutiny, the ability to monetize new reserves through existing offshore infrastructure represents the highest-return exploration strategy available.
Companies and national oil corporations holding underdeveloped acreage adjacent to producing fields should be paying close attention. The Bahr Essalam tie-back is a blueprint, not an exception.
