The Tengiz Field
Tengiz is located on the 2,500 square kilometer (1,600 square mile) project license area which includes the super giant Tengiz field, and a smaller but sizable Korolev field and several exploratory prospects. The Tengiz and Korolev fields have potential for an estimated 750 million to 1.1 billion metric tonnes (6 billion to 9 billion barrels) of recoverable oil. Estimated original oil in place in the drilled and un-drilled portions of Tengiz field is about 3 billion metric tonnes (26 billion barrels). At a world class size of 190 million metric tonnes (1.5 billion barrels), Korolev is one-sixth the size of Tengiz.
Tengiz field is one of the world's deepest developed super giant oil fields, with the top of the reservoir at about 4,000 meters (13,000 feet). Tengiz reservoir is 19 kilometers (12 miles) wide by 21 kilometers (13 miles) long. The oil column measures an incredible one mile thick. The reservoir area is so large that one would have to run nearly two marathons to cover the entire distance around it.
