Eni and BP Announce 2 Tcf Gas Discovery at Temsah Concession Offshore Egypt

Eni has announced a significant natural gas and condensate discovery in Egypt's Eastern Mediterranean with the successful drilling of the Denise W-1 exploration well in the Temsah Concession. Preliminary estimates indicate approximately 2 trillion cubic feet (Tcf) of gas initially in place, along with 130 million barrels of associated condensates, making it one of the largest offshore discoveries in the region in recent years.

The Denise W-1 well is located approximately 70 kilometers offshore in 95 meters of water depth and sits less than 10 kilometers from existing production infrastructure. That proximity to operational facilities opens the door to what Eni described as a fast-track development pathway, significantly reducing the timeline and capital required to bring the discovery to first gas.

Reservoir Quality and Comparison to Temsah

The discovery encountered a gas-bearing sandstone reservoir of excellent quality with approximately 50 meters of net pay. Eni noted that the geological characteristics mirror those of the nearby Temsah field, which has been in continuous production since 2001 and remains a cornerstone of Egypt's offshore gas output.

The Temsah Concession itself was renewed in July 2025 under a binding agreement between Eni, the Egyptian General Petroleum Corporation (EGPC), and the Egyptian Natural Gas Holding Company (EGAS) for a 20-year term. The Denise W-1 drilling represents the first major exploration success under the renewed concession terms.

Joint Venture Structure

Eni operates the Denise Development Lease within the Temsah Concession with a 50% contractor working interest. BP holds the remaining 50%. Day-to-day operations are managed through Petrobel, the joint venture operating company between Eni and EGPC that has overseen Egyptian offshore production for decades.

The partnership between Eni and BP in Egypt dates back years and has produced a series of discoveries in the Eastern Mediterranean, including the supergiant Zohr field discovered by Eni in 2015. While the Denise W discovery is smaller than Zohr, its proximity to existing infrastructure makes it commercially attractive and developable on a faster schedule.

Implications for Egypt's Gas Balance

Egypt has been working to stabilize its domestic gas supply after a period of rising demand and declining output from mature fields. The country shifted from being a net LNG exporter to a net importer in recent years, creating urgency around new exploration and development. A 2 Tcf discovery with fast-track potential could meaningfully contribute to reversing that trend.

The find also reinforces the Eastern Mediterranean's position as a major gas province alongside Israel's Leviathan and Tamar fields and Cyprus's Aphrodite discovery. For Eni, the Denise W result validates its continued investment in Egyptian exploration at a time when the company is also pursuing deepwater opportunities in Libya, Mozambique, and Ivory Coast.

Price Environment and Development Economics

The discovery arrives in a constructive pricing environment for natural gas. Brent crude is trading near $96 per barrel, WTI at approximately $95, and global LNG spot prices remain elevated due to the ongoing disruption at the Strait of Hormuz and competition between European and Asian buyers for available cargoes. Western Canadian Select (WCS) has also strengthened on the back of constrained global supply routes.

For a shallow-water development close to existing infrastructure, the economics of bringing Denise W online are likely favorable even under more moderate price assumptions. Operators like Chevron, Shell, and TotalEnergies are all actively exploring in the Eastern Mediterranean, and a successful fast-track project at Temsah would further validate the region's attractiveness for capital investment.

Eni has not yet disclosed a specific timeline for a development plan submission or first gas target, but the company indicated that appraisal activities and development planning are already under way. Further details are expected as the partnership moves toward a final investment decision in the coming quarters.
