History
Founding and Early Development
GS Caltex was established in May 1967 as Honam Oil Refinery Co. Ltd., marking South Korea's first private oil refining venture. It originated as a 50-50 joint venture between Caltex—then a partnership of Chevron and Texaco—and Lucky-Goldstar Oil, the predecessor to the LG Group, with headquarters in Seoul. This collaboration leveraged Caltex's international expertise in petroleum refining to support South Korea's rapid post-Korean War industrialization, which demanded reliable domestic fuel supplies for economic reconstruction and growth.[4][5][6] The company's initial operations centered on oil refining, commencing with the construction of a refinery in Yeosu, South Jeolla Province. The facility began production in 1969 with an initial capacity of 60,000 barrels per day, focusing on processing crude oil into essential petroleum products like gasoline, diesel, and kerosene to fuel the nation's burgeoning manufacturing and transportation sectors. This setup addressed the acute energy shortages of the era, enabling South Korea to reduce reliance on imported finished fuels and integrate refining into its heavy industry push.[5][4] The 1970s presented significant challenges due to the global oil crises of 1973 and 1979, which disrupted supply chains and spiked prices, straining South Korea's import-dependent economy. Honam Oil Refinery adapted by prioritizing expansions to bolster domestic refining capabilities and secure diverse crude imports. Between 1970 and 1981, the Yeosu plant underwent four major expansions, increasing its throughput and enhancing supply chain resilience through strengthened international sourcing networks. These measures aligned with national policies to mitigate energy vulnerabilities during the shocks, allowing the company to maintain steady production amid volatility.[7] During the 1980s and 1990s, Honam Oil Refinery—renamed LG-Caltex Oil Corporation in 1996—experienced robust growth, evolving from a domestic supplier to a more technologically advanced operator. The company invested in refining upgrades and diversified into petrochemicals, constructing a polypropylene plant in 1988 and expanding into aromatics production in 1990, which improved product yields and operational efficiency. These developments fostered greater self-sufficiency in refining processes through localized technology adoption and capacity enhancements, culminating in exports of petroleum and petrochemical products to Asian markets by the late 1990s. This phase solidified its role in South Korea's energy sector, with refining output scaling significantly to meet rising demand.[5][1]Key Milestones and Expansion
In 2005, following the split of GS Group from LG Corporation, the company was renamed from LG-Caltex Oil Corporation to GS Caltex Corporation, marking a significant corporate restructuring that aligned it with the newly independent GS Holdings as its flagship entity.[8][9] This change reflected the broader demerger of GS affiliates from LG, enabling focused growth in energy sectors while maintaining its joint venture partnership with Chevron.[4] A key expansion milestone occurred in 2009 with the completion of a major heavy oil upgrading (HOU) facility at the Yeosu refinery complex, which contributed to the company's total HOU capacity reaching 274,000 barrels per day by the 2010s.
