The Most Competitive OIL REFINERY in the Asia-Pacific - 669,000 BPD of Crude distillation - 1.8 Mil ton of PX Production (World NO.1 Complex) - 42,700 BPD of Base Oil Capacity

The most competitive and admired
energy & chemistry company

S-OIL, established in 1976 has grown into one of the most competitive oil refiners in the Asia-Pacific region by establishing profitability-oriented management strategies and nurturing dynamic and progressive spirit in the management. We operate the oil refinery facility with the capacity of 669,000 barrels per day (BPD) and other facilities that can produce petrochemicals and lube base oil in the Onsan Refinery in Ulsan. We are strengthening our status as a leader in protecting customers and the environment by producing and supplying the best quality oil products based on the world-class Bunker-C Cracking Center (BCC) and the Xylene Center, a PX plant with the world’s highest production capacity for a single facility.

S-OIL is not only a leader in the local lube base oil market, but also a globally competitive lube base oil maker as it has made bold investments in the high-quality lube base oil business since its foundation succeeding in domestically producing premium lube base oil. S-OIL Total Lubricants, a joint venture with TOTAL Raffinage Marketing S.A. in 2008, has clearly positioned itself as a leader in the domestic lubricant market as well.

Global DJSI World
for nine consecutive years

S-OIL has been listed on the DJSI World (Down Jones Sustainability index) for nine years in a row. In the oil and gas industry, S-OIL is the first and only Asian and Korean oil refinery to be included in the DJSI World list for nine consecutive years. DJSI was an index created by Dow Jones & Company by selecting 10% of leading sustainability driven companies through the integrated assessment of financial, economic, environmental, and social performances of the largest 2,500 firms worldwide. Being included in the DJSI World itself is considered as having long-term competitiveness. The DJSI World recognized our continuous efforts and achievements based on the excellent corporate governance structure and transparent management under the philosophy of sustainable management.

S-OIL included
on the Fortune 500

S-OIL has been repeatedly included on the Fortune 500 that lists the largest companies by total revenue every year by Fortune, an American business magazine, since it was named to the list for the first time in 2007. Being selected for the Fortune 500 proves that S-OIL is a truly world-scale company. S-OIL avoids resting on the laurels but continues to evolve; S-OIL was not content with the present status and for its sustainable development has built the Magok R&D Center and engaged in large-scale new investment projects such as setting up the Residue Upgrading Complex and the Olefin Downstream Complex
