ENI announced it had made a “world class supergiant” gas discovery at its Zohr Prospect, in the deep waters of Egypt.

The discovery could hold a potential of 30 trillion cubic feet of lean gas in place covering an area of about 100 square kilometres, the company said in a late August announcement.

According to Eni, Zohr is the largest gas discovery ever made in Egypt and in the Mediterranean Sea.

Eni will immediately appraise the field with the aim of accelerating a fast track development of the discovery that will utilise at best the existing offshore and onshore infrastructures.

The discovery well Zohr 1X NFW is located in the economic waters of Egypt’s offshore Mediterranean, in 4,757 feet of water depth.

Zohr 1X NFW was drilled to a total depth of approximately 13,553 feet and hit 2,067 feet of hydrocarbon column in a carbonate sequence of Miocene age with excellent reservoir characteristics.

Zohr’s structure has also a deeper Cretaceous upside that will be targeted in the future with a dedicated well, Eni said.

Eni chief executive Claudio Descalzi said it is an outstanding result and reconfirms the potential opportunities in Egypt.

“Our exploration strategy allows us to persist in the mature areas of countries which we have known for decades and has proved to be winning, reconfirming that Egypt has still great potential.”

“This exploration success acquires an even greater value as it was made in Egypt which is strategic for Eni, and where important synergies with the existing infrastructures can be exploited allowing us a fast production startup,” Mr Descalzi said.

Eni, through its subsidiary IEOC Production B.V., holds a 100 per cent of the contractor’s working interest in the Shorouk Block and is the operator of the concession.

Eni has been present in Egypt since 1954 through its subsidiary IEOC and is the main hydrocarbon producer in Egypt, with a daily equity production of 200,000 barrels of oil equivalent, the company said.
