Italian energy company Eni has discovered a "supergiant" natural gas field off Egypt, it revealed.

A company statement today is calling it the "largest-ever" found in the Mediterranean Sea.

Eni said after full development, the discovery will be able to ensure satisfying Egypt's natural gas demands "for decades."

The news came a day after Eni chief executive Claudio Descalzi met in Cairo with Egyptian president Abdel-Fattah el-Sissi, the Egyptian leader's office said.

Eni said the discovery - made in its Zohr prospect "in the deep waters of Egypt" - could hold a potential 30 trillion cubic feet of gas over an area of 100 sq km.

The discovery well is about 120 miles from the Egyptian coast, and is at a depth of 4,757ft in the Shorouk Block, the company said.

"Zohr is the largest gas discovery ever made in Egypt and in the Mediterranean Sea and could become one of the world's largest natural gas finds," Eni said in a statement.

"The discovery, after its full development, will be able to ensure satisfying Egypt's natural gas demand for decades."

"Eni will immediately appraise the field with the aim of accelerating a fast-track development of the discovery," the energy company said.

Mr Descalzi was quoted by Eni as saying that the discovery reconfirms that "Egypt still has great potential" energy-wise.

He said "important synergies with the existing infrastructures can be exploited, allowing us a fast production start-up".

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