Italian energy major Eni announced on 16 March 2026 that it has made two significant new gas discoveries offshore Libya, with preliminary estimates pointing to combined resources in excess of one trillion cubic feet. The finds, made through an active exploration campaign in the Mediterranean, mark one of the most consequential upstream developments in the North African country in years and add fresh momentum to a development programme that is already one of the busiest Eni has run in Libya in over a decade.
Two New Wells Encounter Gas-Bearing Reservoirs South of Bahr Essalam
The discoveries were made at two adjacent geological structures identified as Bahr Essalam South 2 and Bahr Essalam South 3, drilled by the B2-16/4 and C1-16/4 wells respectively. Both wells sit approximately 85 kilometres off the Libyan coast in roughly 650 feet of water, positioned 16 kilometres south of the Bahr Essalam gas field, which has been Libya's largest producing offshore gas asset since coming onstream in 2005.
Gas-bearing intervals were encountered in both wells within the Metlaoui Formation, the primary productive reservoir across this part of the Mediterranean basin. Data acquired during drilling confirmed the presence of a high-quality reservoir, and productive capacity was validated through a well test already carried out on the first well. The combination of reservoir quality and confirmed flow rates gives Eni a strong technical foundation from which to accelerate development decisions.
Proximity to Existing Infrastructure Puts Production on a Fast Track
What distinguishes these discoveries commercially is not only their scale but their location. Sitting just 16 kilometres from the Bahr Essalam field's existing offshore infrastructure, both structures are candidates for rapid tie-back development, a route that avoids the cost and timeline burden of building standalone facilities from scratch. This positions Eni to move from discovery toward production at a pace that deepwater finds in less developed basins simply cannot match.
That development pathway connects directly into an upgrade programme already underway at Bahr Essalam. A gas compression project on the Sabratha platform is designed to sustain reservoir pressure and maintain production levels across the field, with full integration expected by the close of the first quarter of 2026. Once operational, the compression system is projected to add around 100 million standard cubic feet per day, stabilising existing output and improving overall system efficiency ahead of the new volumes that the two southern structures will eventually contribute.
Three Development Projects Running Simultaneously as Eni Expands Its Libya Portfolio
The discovery does not stand alone. Eni currently has three development projects in execution in Libya, two of which are scheduled to begin production in 2026. The Bouri Gas Utilization Project, targeting the recovery of associated gas previously flared at the offshore Bouri field, is scheduled for start-up in the third quarter of this year and is expected to contribute between 100 and 120 million standard cubic feet per day while simultaneously reducing upstream emissions in line with the company's zero-flaring objectives.
Looking further ahead, the Structures A&E development remains the centrepiece of Eni's Libya expansion strategy. Part of an $8 billion investment programme, the project is on track to reach a production plateau of 750 million standard cubic feet per day by 2027. Eni's equity production in Libya stood at approximately 162,000 barrels of oil equivalent per day in 2025, a figure that its current project pipeline is designed to grow substantially over the next two years.
Europe's Shifting Gas Supply Map Puts Libya's Mediterranean Position Back in the Spotlight
The timing of this announcement carries significance beyond the technical. With European gas markets still navigating the consequences of supply disruptions from the Middle East and demand for non-Russian, non-Gulf supply at levels not seen in years, Libya's ability to pipe gas directly to Italy via the GreenStream pipeline has rarely looked more strategically valuable.
Eni has operated in Libya since 1959 and remains the country's leading international operator. Its continued commitment to exploration alongside active development signals that Libya is not a legacy position being managed for decline but a growth asset in a supply environment where proximity to Europe and fast-track development capability have become defining commercial advantages.
For Libya itself, the discoveries arrive at a moment when the government has been working to attract sustained upstream investment and demonstrate to international partners that the country's subsurface potential remains significant. Whether political conditions continue to support the pace of development that Eni's programme demands remains the central variable, but on the technical and commercial side, what these two wells have returned is a picture of considerable promise.
