Lukoil has completed the acquisition of a 50% operator interest in the Block 4 project in Mexico for $435 million. The license areas of the project include two oil fields Ichalkil and Pokoch with recoverable hydrocarbon reserves of 564 million boe, of which more than 80% is oil. At the end of last year, production was already started at the fields, but the project will require about $500 million in investments.
