PetroChina ranks fifth globally by refining throughput, processing approximately 170–180 million tonnes per annum (MTA) across a network of refineries that stretches from northeast China to Guangdong province. As the publicly listed arm of China National Petroleum Corporation (CNPC), PetroChina downstream refining sits at the centre of China’s energy supply chain — integrating crude production, processing, petrochemicals, and retail fuel distribution at a scale few companies outside China can match.
Company Overview
PetroChina Company Limited was formed in 1999 as CNPC’s vehicle for public capital markets, listing on the Hong Kong Stock Exchange (HK: 0857) and the Shanghai Stock Exchange (SH: 601857). It held a New York Stock Exchange listing until 2022, when it voluntarily delisted from the NYSE alongside several other major Chinese state enterprises. CNPC retains approximately 86% ownership, giving Beijing effective control over strategic decisions including capital allocation and refinery investment.
The company operates an integrated model spanning upstream exploration and production, refining and chemicals, natural gas distribution, and retail marketing through its extensive petrol station network across China. Revenue reached approximately RMB 3.0 trillion (~$416 billion USD) in 2023, placing PetroChina among the largest companies in the world by turnover.
Refining Network & Key Assets
PetroChina downstream refining capacity of 170–180 MTA places it behind only Sinopec, ExxonMobil, Shell, and Saudi Aramco in global throughput terms. The refinery estate is weighted toward northern and northeastern China, where crude pipelines from Daqing — China’s historic oil heartland — have historically fed processing capacity.
Key assets include Fushun Petrochemical in Liaoning province, Daqing Petrochemical in Heilongjiang, and Lanzhou Petrochemical in Gansu, each representing decades of integrated refining and chemicals production. The most significant recent addition is Guangdong Petrochemical in Jieyang, Guangdong province — a 40 MTA refinery-chemical complex that began operations in 2023 and ranks among China’s largest single-site refinery-chemical integrations. The Guangdong complex is designed to produce high-value petrochemical feedstocks alongside transport fuels, reflecting PetroChina’s push toward higher-margin output. As of 2026, the facility is ramping toward full design capacity.
Petrochemical production across the network includes ethylene, synthetic fibres, and fertilisers — extending the value chain beyond fuel refining and providing exposure to China’s domestic industrial demand base. PetroChina features prominently in rankings of the top 10 downstream oil and gas companies globally.
Natural Gas, LNG & Pipeline Position
PetroChina is China’s largest natural gas producer and a major distributor, supplying residential, industrial, and power generation consumers across the country. Gas and LNG have been designated strategic growth priorities as China targets a lower-carbon energy mix through the 2030s and 2040s.
The company holds interests in LNG import terminals and participates in long-term supply agreements supporting China’s growing regasification infrastructure. A significant structural change occurred in 2020, when CNPC transferred the national pipeline grid assets to PipeChina — China Oil and Gas Pipeline Network Corporation — a newly created state entity designed to provide open-access pipeline infrastructure. PetroChina retains pipeline interests but is no longer the operator of China’s national transmission grid. This separation mirrors regulatory models used in Europe and was intended to encourage third-party access and competition in gas supply.
International Operations
PetroChina’s most prominent international asset is its participation in the Rumaila oilfield in southern Iraq — one of the world’s largest producing fields, operated under a BP-led consortium. Rumaila produces approximately 1.4 million barrels per day and represents a cornerstone of Iraq’s export volumes. PetroChina holds a significant equity stake in the technical service contract structure governing the field.
In Kazakhstan, PetroChina operates through joint ventures with KazMunayGas, maintaining upstream positions in a producing basin with established infrastructure. The company has historically held oil sands positions in Canada and upstream assets in Sudan and Niger, though exposure to higher-cost or higher-risk international positions has been managed down in recent years as capital discipline has increased. As one of the largest upstream oil and gas companies globally, PetroChina reported upstream production of approximately 1.67 billion BOE in 2023.
2026 Strategy
The Guangdong Petrochemical complex ramp-up is the defining near-term capital story for PetroChina downstream refining in 2026. Bringing 40 MTA of integrated capacity to full utilisation is a multi-year process, and the facility’s petrochemical integration is expected to drive margin improvement as China’s appetite for high-value chemical products grows alongside its manufacturing base.
On gas and LNG, PetroChina is investing in supply security and distribution reach, aligned with national targets to increase gas as a share of China’s primary energy mix. Carbon neutrality by 2050 is a stated corporate target, supported by green hydrogen pilot projects and efficiency programmes across the refining estate. At Rumaila in Iraq, output expansion continues under the BP-led consortium — a long-cycle asset that contributes steady production volumes to PetroChina’s upstream base. The company’s pipeline interests and infrastructure position are also detailed in coverage of the top pipeline companies operating globally.
