Iraq's Prime Minister Mustafa al-Kadhimi said on July 26 he wants another American company to replace Exxon Mobil Corp. when it exits Iraq.

Exxon, which in 2019 had looked poised to move ahead with a $53 billion project to boost Iraq's oil output, has been seeking to sell its 32.7% stake in one of Iraq's biggest oil fields, West Qurna 1.

"Exxon Mobil is considering exiting Iraq for reasons that are to do with its internal management practices, decisions, and not because of the particular situation in Iraq," Kadhimi told a small group of reporters in Washington after talks with President Joe Biden.

"When Exxon Mobil departs, we will not accept its replacement to be other than another American company," he added, speaking through a translator.

Kadhimi did not specify which American companies might be interested. Chevron Corp. also operates in Iraq.

In May, Iraq's Oil Minister Ihsan Abdul Jabbar said the country was considering purchasing Exxon's West Qurna stake through state-owned Basra Oil Co.

When contacted by Reuters, Exxon said in a statement that it had entered into an agreement with Petrochina and China's offshore oil and gas major CNOOC Ltd. to sell its West Qurna interest in January 2021.

Exxon added that Indonesia's Pertamina has since exercised its right to purchase the interest that would have been sold to CNOOC.

The statement also said Exxon has filed for arbitration against Basra Oil over Exxon's sale of the West Qurna stake. It did not mention a sale to a U.S. firm.

"The sale aligns with Exxon Mobil’s strategy to focus on advantaged assets with the lowest cost of supply, including developments in Guyana, Brazil and the U.S. Permian Basin," the statement said.

Securing foreign investment is critical for Iraq, the second-largest producer in OPEC. Oil revenue represents at least 95% of Iraq's income.
