Officials from the world’s largest listed oil producer recently held talks with Egypt’s petroleum ministry to discuss investments in oil and gas production, known as upstream operations, Petroleum Minister Tarek El Molla told Reuters.

“We have been discussing with them, visiting them. They’ve visited us... We are exploring all opportunities for having more and further upstreamers in Egypt,” Molla said on the sidelines of an OPEC meeting in Vienna.

“I would be happy to have them with us,” he said, adding that no decision has been made yet.

Exxon declined to comment. The Irving, Texas-based company currently has no upstream operations in Egypt, according to its website.

The company is looking at exploring the eastern Mediterranean offshore basin, according to industry sources.

Italy’s Eni  this month is set to begin producing gas from the Zohr field in the Mediterranean, among the biggest discoveries of the past decade.

“After Zohr there was a reassessment of the portfolio profitability in Egypt” by Exxon, one source said, adding that Exxon was looking for “tier one assets” with significant potential.

Exxon is also considering opportunities in the Red Sea, where Cairo is preparing to tender exploration blocks, industry sources briefed on the matter told Reuters.

Egypt in 2016 had reserves of 3.5 billion barrels of oil and 1.8 trillion cubic meters of gas, according to BP’s Statistical Review of World Energy.
