Not to split hairs- but it's LUKoil that has the 68% share of the oil fields, and from that- Mother Russia has a 14% stake (in the 68%). My reason for pointing this out is to address who the other 86% share in ownership of LUKoil is... who are they ?
68% = 272 billion $, 14% = 38.08 billion $
Does Iraq own the remainder (32%) of the oil fields ?
Iraq. We have a 68.5% interest in a PSA relating to the development of the second stage of the West Qurnah oil field. Other parties involved include the Russian Foreign Economic Association Zarubezhneft, the Russian State Foreign Economic Association Machinoimport and the Iraqi Oil Ministry. The agreement terminates in 2020 and contemplates that the parties will invest a minimum of $6 billion on a pro rata basis. To date we have limited our activities in Iraq to comply with United Nations sanctions as implemented and followed by the Russian Federation and have delayed our performance of certain obligations under the agreement. We will continue to abide by such sanctions and do not currently anticipate any capital expenditures for such project.
