The Iraqi government said Friday that Exxon Mobil Corp. (XOM) could lose its current contract to redevelop the giant West Qurna oil field if it proceeds with an agreement to explore for oil in the Kurdish region of the country.

The spat highlights the political challenges for foreign companies operating in
Iraq and threatens to further inflame tensions between the Baghdad government and the semi-autonomous Kurdish region, who have long disputed the right to grant oil licenses.

"Exxon should choose between either continuing with its deal with the Kurdistan Regional Government or lose its contract in southern
Iraq ," Abdul Mahdi al-Ameedi, head of petroleum contracts and licensing directorate at Iraq 's Oil Ministry, said in an interview with Dow Jones Newswires.

ExxonMobil has signed agreements to explore for oil and gas in six blocks in the Kurdish region of
Iraq , Michael Howard, communications adviser to the resources minister of the Kurdistan Regional Government, told Dow Jones Newswires.

ExxonMobil declined to comment.

A number of smaller foreign companies already produce oil in
Iraq 's Kurdish region, but ExxonMobil is the first of the major international oil companies to reach such an agreement.

The KRG is embroiled in a long and often contentious dispute with
Iraq 's central government over oil licenses issued to foreign companies. The dispute has periodically caused the disruption of oil exports from the Kurdish region.

Iraq 's central government sent ExxonMobil three warning letters before it signed its deal to explore for oil and gas with the KRG, al-Ameedi said. "The letters stressed that, according to regulations of the central government, any company which signs deals with the KRG wouldn't be allowed to work in the center and south of the country," he said.

"We are not going to give Exxon a long time to decide," he said. "This is very sensitive issue and companies working in southern
Iraq such as BP, Lukoil, Shell are watching the situation closely."

ExxonMobil is already producing around 370,000 barrels a day of oil from the
West Qurna field in southern Iraq , under a service contract with the Baghdad government. Many other large oil companies, including BP PLC (BP), Royal Dutch Shell PLC (RDSB.LN), Eni SpA (E) and Lukoil Holdings (LKOH.RS) have similar contracts to redevelop aging oil fields.

These contracts have helped
Iraq increase its oil output to around 2.7 million barrels a day in recent months, compared with 2.4 million barrels a day a year ago. They haven't been especially lucrative for the companies, who receive a nominal fee of a few dollars for each extra barrel of oil they can produce.

Al-Ameedi said the KRG has approached other companies operating in southern
Iraq , without naming the companies. KRG communications adviser Howard denied this.

A spokesman said BP isn't talking to the KRG about similar deals. "We're quite happy with what we've got in
Iraq , namely our commitment to developing Rumaila, the fourth-largest oil field in the world," the spokesman said.

Shell declined to comment.

Iraq 's council of ministers is expected to meet immediately after the Muslim Eid holiday to decide whether ExxonMobil's existing contract to develop the super giant West Qurna oil field remains valid, al-Ameedi said. si�gap� `^ mso-fareast-language:EL;mso-bidi-language:AR-SA'>South Africa to talk to President Jacob Zuma about exporting some of the Mozambique gas to South Africa .
