PetroChina

PetroChina is a major Chinese oil and gas company engaged in the exploration, production, refining, and marketing of petroleum and petrochemical products. It operates both upstream and downstream businesses, supplying fuels and lubricants to domestic consumers and exporting crude oil and refined products to international markets. The company is headquartered in Beijing, China. PetroChina’s activities include the development of oil and gas fields, the operation of refineries, and the manufacture of chemicals such as polyethylene and polypropylene. Its integrated approach enables it to manage the value chain from extraction to end‑user distribution. The firm serves a broad customer base that includes industrial users, transportation operators, and retail motorists.

As a subsidiary of China National Petroleum Corp, PetroChina draws on the parent’s extensive resource portfolio and infrastructure. It is listed on the Hong Kong and Shanghai stock exchanges while remaining a state‑owned enterprise under the ultimate oversight of the Chinese government. The company maintains a significant domestic footprint, with a widespread network of service stations and pipelines that transport hydrocarbons across the country. PetroChina is often cited for its contribution to China’s energy security, providing a stable supply of crude oil and refined products to support national economic activity. The WannaCry ransomware attack in May 2017 affected some of its petrol stations, disrupting card payment systems and forcing customers to seek alternative payment methods. These facts illustrate PetroChina’s scale, operational scope, and structural ties within China’s state‑led energy sector.
