- Oil Refinery Throughput refers to the actual volume of crude oil and other refinery feedstocks processed by petroleum refineries during a given period.
South Korea Oil Refinery Throughput was 2,758 Thousand Barrels Daily in 2023, down 1.9% on 2022. The Oil Refinery Throughput dataset of South Korea from 2015 to 2023 provides a comprehensive overview of the country's petroleum refining activity, highlighting annual crude oil processing volumes, refinery performance, and developments across the downstream oil industry. Measured in million barrels daily, the dataset represents the actual volume of crude oil processed by domestic refineries each day.
South Korea Oil Refinery Throughput moved from 2,784 Thousand Barrels Daily in 2015 to 2,758 Thousand Barrels Daily in 2023 (−0.9%), an average of −0.1% a year. The series high was 3,061 Thousand Barrels Daily in 2017 and the low 2,634 Thousand Barrels Daily in 2021.
The gap between the series high (2017) and low (2021) is 427 Thousand Barrels Daily. The sharpest single-year move was −8.3% in 2020.
Among the 44 countries in this dataset, South Korea ranks 6 for 2023, behind U.S. (15,963 Thousand Barrels Daily) and China (15,102 Thousand Barrels Daily). It accounts for 3.3% of the global total in 2023.

Data definition
Oil Refinery Throughput — - Oil Refinery Throughput refers to the actual volume of crude oil and other refinery feedstocks processed by petroleum refineries during a given period. It is typically measured in thousand barrels per day (kb/d) and represents the operational output of the refining sector rather than its installed capacity. This indicator reflects the extent to which refinery infrastructure is utilized to convert crude oil into refined petroleum products such as gasoline, diesel, jet fuel, kerosene, fuel oil, liquefied petroleum gas (LPG), and other petroleum products. Oil Refinery Throughput is widely used to assess refinery operations, downstream petroleum activity, fuel production levels, and the efficiency of refinery utilization.
The data includes the actual quantity of crude oil and eligible refinery feedstocks processed by petroleum refineries during the reporting period. It covers throughput from both public and privately operated refineries, including onshore and, where applicable, offshore refining facilities. The indicator reflects crude oil processed into refined petroleum products regardless of whether the crude oil is domestically produced or imported. It includes refinery operations across all major processing units involved in converting crude oil into finished petroleum products. Data is compiled from national energy authorities, refinery operators, and standardized international energy databases using internationally recognized reporting methodologies, enabling consistent comparison of refinery throughput across countries and over time.
The data excludes refinery nameplate capacity, crude oil production, crude oil reserves, oil consumption, imports and exports of refined petroleum products, and refinery utilization rates when reported separately. It does not include production from natural gas processing plants, biofuel refineries, synthetic fuel facilities, gas-to-liquids (GTL), or coal-to-liquids (CTL) plants unless specifically classified within refinery operations. The indicator also excludes petrochemical manufacturing processes that do not involve crude oil refining and does not directly measure refinery efficiency, product quality, profitability, or environmental performance. Minor variations may occur due to differences in national reporting standards, feedstock classifications, refinery accounting practices, and statistical estimation methodologies across countries.

Oil Refinery Throughput is widely used to assess refinery operations, downstream petroleum activity, fuel production levels, and the efficiency of refinery utilization.
It serves as an important indicator of refinery utilization, fuel production, industrial efficiency, energy security, and South Korea's role as a major refining and petroleum products export hub in Asia.
South Korea recorded oil refinery throughput of 2.78 million barrels daily in 2015, increasing to 2.93 million barrels daily in 2016 and 3.06 million barrels daily in 2017, the highest level during the early review period. Throughput remained strong at 3.03 million barrels daily in 2018 before easing to 2.92 million barrels daily in 2019. In 2020, refinery throughput declined to 2.68 million barrels daily because of reduced fuel demand and pandemic-related market disruptions. Processing volumes fell slightly to 2.63 million barrels daily in 2021, recovered to 2.81 million barrels daily in 2022, and moderated marginally to 2.76 million barrels daily in 2023, reflecting stable refinery operations and resilient downstream demand.
Overall, the dataset indicates relatively stable refinery throughput with moderate fluctuations throughout the review period. Despite temporary declines during the pandemic, refinery activity recovered steadily, supported by strong export demand and improving refinery utilization.
The dataset is valuable for evaluating South Korea's refinery throughput trends, analyzing downstream industry performance, and assessing crude oil processing activity. It supports refinery utilization analysis, investment planning, energy security assessments, and policy evaluation while providing valuable insights for researchers, analysts, industry stakeholders, and policymakers studying refinery efficiency, infrastructure utilization, and the long-term competitiveness of South Korea's petroleum refining industry.
