CCUS project at Jilin Oilfield

Jilin Oilfield has independently developed core technologies for carbon dioxide capture, storage and enhanced oil recovery (CCUS-EOR), and has created China's first and Asia's largest full industry chain and full-process CCUS-EOR demonstration project. Within China, this project is the first to adopt centralised CO2 injection technology, has the largest hydrocarbon pore volume (HCPV) injected, the most comprehensive CCUS process, the most CO2 injected underground, and the best oil recovery performance. As of the end of 2024, over 3.50 million tonnes of CO2 have been injected and stored under Jilin Oilfield, the highest storage amount in China, which is equivalent to planting more than 30 million trees. The project has therefore made significant contributions to the reduction of GHG emissions and the mitigation of climate change.

Independent Research and Development, Creating a Complete Set of CCUS Technology. Jilin Oilfield has continuously researched the mechanisms of CO2 oil recovery, capture, transportation, and injection technologies. It has gradually carried out pilot tests to adjust and perfect the supporting technologies for the entire CCUS process and independently developed a technology that extracts and recycles energy-associated CO2 for underground injection—the first of its kind in China. Jilin Oilfield has also built and is operating China’s first industrial-scale CO2 recycling and injection station. This enables “zero emission” of associated gas, completing the full technological framework for CO2 capture, transportation, injection and recycling.

Committed to the Concept of Shared Development, Enhancing CCUS Social Benefits. Jilin Oilfield has formed collaborative alliances with Jilin Petrochemical, Daqing Petrochemical and other companies to join hands with other upstream carbon capture companies in forming a local green and low-carbon industrial cluster, fostering the green transition of the entire sector. Additionally, Jilin Oilfield has built a CCUS technology training base to cultivate CCUS talents for the society, thus completing the development of a CCUS training system.
