About the Project

PL-4 process line of the oil and gas processing facility (OGPF) at the Eastern area of the Orenburg oil-and-gas-condensate field. PL-4 carries out primary processing of oil and gas for transportation to the Orenburg gas processing plant. Despite challenging conditions and large H2S content in the oil, the technology developed by OZNA engineers is capable to ensure high processing quality for oil products: the chloride content in the output oil does not exceed 100 mg/l; the water cut is 0.5 % by weight max.
