Iran has sold its first cargo of West Karoun crude to Spain’s Repsol. Iran exported 2.4 million bpd of crude oil last month, and 300,000 bpd of natural gas condensate. National Iranian Oil Co. has already circulated samples of the heavy oil to some customers. Production from the West Karoun oil fields has nearly doubled in the past year, convincing Repsol to agree to take up 500,000 barrels of oil.
