URUMQI, December 29 (Xinhua) — The Xinjiang oilfield, one of northwest China's largest oil bases, has injected more than 1 million tons of carbon dioxide (CO2) into the oil reservoir by 2025 as of December 28. The China National Petroleum Corporation (CNPC), which announced the achievement on Monday, hailed it as a breakthrough in the large-scale application of carbon capture, utilization, and storage (CCUS) technology in the country.
The Xinjiang oil field, located in the Junggar Basin of the Xinjiang Uygur Autonomous Region and the first in China to be classified as a major oil producer, has once again become the country's largest in annual carbon dioxide injection volume.
In recent years, the oil field has been studying and developing a method of enhancing oil recovery using CO2, which is captured and re-injected underground.
As Shi Daohan, executive director and party secretary of the Xinjiang Oilfield, noted, one million tons of CO2 injected into oil reservoirs is equivalent to nearly nine million trees in terms of carbon storage.
According to him, specialists had to overcome a number of technical challenges to master the CCUS technology. Innovations in management, technology, and production helped them achieve this. As a result, the annual CO2 injection volume was increased from 126,000 tons in 2022 to 1 million tons in 2025, bringing the total injection volume to over 2 million tons.
CCUS technology achieves a win-win outcome in terms of reducing harmful emissions and increasing oil production, contributes to the achievement of carbon peaking and carbon neutrality goals, and is of strategic significance to ensuring the country's energy security, said Ding Chao, head of the Xinjiang Oil Field Development Department.
The estimated potential capacity of underground CO2 storage reservoirs in the Xinjiang oil field's production zones could reach 2 billion tons. Furthermore, the concentration of industrial enterprises nearby is noted to create favorable conditions for the development of a large industrial cluster based on CCUS.
China plans to achieve peak carbon emissions by 2030 and carbon neutrality by 2060. -0-
