Greek oil and gas company Energean is ready to buy and operate a 45% stake in the offshore gas field Gaza Marine as soon as both the Israeli and Palestinian authorities give their green light, its CEO said on July 6.

The field has long been seen as an opportunity for the cash-strapped Palestinian Authority to join the eastern Mediterranean gas bonanza, providing a major source of income to reduce its reliance on foreign aid and Israeli energy.

But Palestinian political disputes and conflict with Israel, as well as economic factors, have delayed plans to develop the field.

Energean CEO Mathios Rigas told Reuters on July 5 that the company was ready to buy the gas field stake “if that is something the host governments approve”. “We have proven we can get gas flowing quickly,” he said.

Gaza Marine, located about 30 km (20 miles) off the Gaza coast between the giant gas fields Leviathan and Zohr, is estimated to hold over 1 trillion cubic feet of natural gas, the equivalent of Spain’s consumption in 2016. But plans to develop it have been put off several times over the past decade.

Earlier this year Shell (NYSE: RDS.A) relinquished the 55% stake in the field that it took over as part of its acquisition of BG Group in 2016, after struggling to find a buyer.

The Palestine Investment Fund (PIF) then became the field’s sole owner. It is now looking for an operator and buyer for a 45% stake.

A PIF official, who asked not to be named, told Reuters that negotiations were ongoing with several potential international operators.

“PIF and its partners are very keen and committed in accelerating the exploitation of Gaza marine. The final decision will be made in coordination with the Palestinian government and for the best interests of the Palestinian economy.”

Israel has said in the past it supports the field’s development.

The gas would most likely go to Israel’s Ashkelon natural gas terminal and from there to a Palestinian power plant in Jenin in the West Bank, according to a source with knowledge of the matter.
