Business Overview
Refinery production
GS Caltex imports 80 types of crude oil from some 30 countries spread across the Middle East, US, Southeast Asia, Australia and Europe. Diversified sourcing ensures a stable supply. We produce high-quality petroleum products using our refining capacity of 800,000 barrels per day (bpd) and cutting-edge production systems that include facilities to desulfurize kerosene and diesel.
Additionally, heavy oil upgrading(HOU) facility, the largest in the nation, has a capacity of 275,000 bpd and produces light oil products and high-grade gasoline. It has brought GS Caltex a step closer to realizing a ‘perfect complex.’
