Energy Window International– Eni said it has made a significant gas and condensate discovery in Egypt, with the successful drilling of its Denise W 1 exploration well in the Temsah Concession, said to be located offshore in the Eastern Mediterranean. It said preliminary estimates indicated about 2 trillion cubic feet (Tcf) of gas initially in place (GIIP) and 130 Mbbl of associated condensates.
The Denise W discovery Eni said told Energy Window International (Media) in an email statement, lies 70 km offshore in 95 m of water depth and less than 10 km from existing infrastructure which it sees as an enabler in fast-tracking development. The facility features a gas-bearing sandstone reservoir of excellent quality with about 50 m of net pay. Eni compares it with its “nearby” Temsah field which it says has been in production since 2001
The discovery according to the firm reinforces its commitment to supporting Egypt’s national goals of boosting reserves and increasing gas production, thereby strengthening the country’s energy security. It also confirms its successful strategy in substantially rejuvenating producing assets through near-field and infrastructure-led exploration, Eni said.
It said the drilling of Denise W-1 followed the binding agreement signed in July 2025 with EGPC and EGAS for a 20-year renewal of the Temsah Concession. Eni says it operates the Denise Development Lease of the Temsah Concession with a 50% contractor working interest, alongside bp which holds the remaining 50%. The asset is operated through Petrobel, the joint venture operating company between Eni and EGPC, Eni said.
The Italian firm said that it has been active in Egypt since 1954, holding a diversified portfolio spanning exploration, development, and production, with oil and gas production of 242 kboed equity in 2025.
