S-OIL Marks 50 Years, Declares Shift to Energy and Chemical Giant with Shaheen Project Nearing Completion

South Korean refiner S-OIL is marking its 50th anniversary by announcing its strategic pivot towards becoming a future-oriented energy and chemical company. Founded in 1976, S-OIL has grown into a leading domestic refiner through continuous investment and management innovation over the past five decades. The company boasts world-class crude oil refining capacity at a single plant, a unique domestic production system for Group I, II, and III lubricant base oils, and large-scale petrochemical facilities.

Anwar Al-Hejazi, CEO of S-OIL, stated, "2026 is the 50th anniversary of S-OIL's founding and a meaningful year as the Shaheen project bears fruit. Based on the competitiveness and innovative DNA accumulated over the past 50 years, we will continue to grow into the most competitive, innovative, and trusted energy and chemical company for the next 50 years."

In response to the global energy transition and carbon neutrality trends, S-OIL has invested over 14 trillion won in the last decade to ensure sustainable growth. The company laid the groundwork for expansion into petrochemicals beyond its refining-centric business structure with the RUC & ODC project, which began commercial operation in 2018. This year, coinciding with its 50th anniversary, S-OIL is on the verge of completing the Shaheen project, the largest of its kind in South Korea's petrochemical industry, with a total investment of 9.258 trillion won.

The Shaheen project involves advanced facilities designed to convert low-value fractions from the crude oil refining process into high-value petrochemical products. S-OIL anticipates this project will significantly enhance the value chain competitiveness of the domestic petrochemical industry, which has faced challenges from global supply chain shifts and oversupply from China. The company has also strategically expanded its petrochemical business, notably with the 2011 launch of the world's largest single paraxylene production facility, a key raw material for polyester fibers and PET bottles.
