Tuapse field

The Tuapse field is a large offshore oil field located in the Black Sea, roughly 4,300 mi2 in size and between 1000 and 2000 m underwater, containing between 2.2 and 7.2 Goilbbl of oil.

History
In August 2003, Rosneft was awarded a license to explore the field, allowing the company to carry out surveys and small-scale exploratory drilling.

In February 2011, Rosneft and ExxonMobil reached a preliminary agreement to develop the field; the agreement was officially announced on 30 August 2011 as part of a US$3.2 billion joint venture between the two companies that also included the development of the East-Prinovozemelsky field in the Arctic Kara Sea. Under the terms of the contract, Rosneft will own two-thirds of the joint venture, with Exxon controlling the remainder.

After Russia annexed Crimea in 2014, the US imposed sanctions that blocked the partnership. ExxonMobil was later granted a limited waiver to maintain "administrative actions" in the joint venture, and in March 2017 applied to the US government for a full waiver that would allow it to resume drilling in partnership with Rosneft. The request was denied in April, leaving ExxonMobil with little chance of beginning drilling before the joint venture agreement expired at the end of the year.
