Exxon Mobil Group, whose CEO is Rex Tillerson, whom Donald Trump appointed the US secretary of state, has serious business interests in Azerbaijan. Exxon Mobil was founded in Azerbaijan in 1995. The Azerbaijani ExxonMobil owns 8 percent of the stake in the oil development project of Azeri-Chirag-Deepwater Gunashli.

As Reuters announced, in July of this year, the American oil giant Exxon Mobil and British BP did not reach an agreement on the major deal of processing Azerbaijani mines, blocking the so-called extension of the "Contract of the Century".

The BP that operated the Azeri-Chirag- Gunashli (ACG) in the Caspian Sea, which owns the 10th part of its world exportation, had previously agreed to extend the terms of a 30-year contract with the government, the sources reports.

However, Exxon, which accounts for 1 percent of hydrocarbon extraction of ACG, in 2014, after almost double fall in world oil prices expressed a hope for a better condition for the deal.

As a result, negotiations on the draft, which would allow them to produce more oil at current price of $ 100 billion, entered a deadlock, intensifying existing tensions between Exxon CEO Rex Tillerson and his BP partner Bob Dudley, said the sources.

8 years is left for the current argents to expire. However, in case of such long-term contracts of mutual processing of the mines, it is accepted to begin negotiations as soon as possible, preferably 10 years earlier, to plan new investments. Consortium partners have already invested $ 32 billion into the project.

Three fourth of the total Azerbaijani oil export, or about 600 thousand barrels per day of oil production, 0.7 percent of world production is at stake. Mining processing is carried out under the agreement between the consortium members and the government of Azerbaijan.

BP’s share in the project makes 35.8 percent, while Exxon’s only 8 percent. Among other members of consortium are Azerbaijan's SOCAR state oil company and American Chevron; the share of each makes 11 per cent.  The Japanese Inpex has the same share. Norwegian Statoil reached 8.6 percent, the Turkish TPAO, Japanese ONGC and Indian Itochu have smaller shares.

The mines should have produced 1 million barrels per day, but in 2010, after reaching a daily production of 820 thousand barrels, they registered a decrease. The Azerbaijani President Ilham Aliyev accused BP of giving "false promises".

Azerbaijan was even talking about a possibility of processing its own mines in 2024, after the contract expires. However, BP managed to begin negotiations on a contract extension until 2040, possibly until 2060, at a price of $ 50 per barrel at the cost of $ 100 billion till 2 billion barrels of oil to produce.
