The shale oil resources at Changqing are characterized by thin oil layers and high variability, presenting unique challenges. As a rare low-pressure shale oilfield globally, it requires advanced techniques for seismic exploration and reservoir fracturing, which complicates cost-effective production.
Since 2018, Changqing Oilfield has significantly increased its shale oil production capacity through advancements supported by Chinese scientific and technological initiatives. The oilfield established a large-scale underground hydraulic fracturing experimental site, enhancing key technologies. These efforts have boosted single-well output from 1.5 tonnes to 18 tonnes, improving efficiency.
The oilfield has also streamlined its operations, reducing the workforce needed for 1 million tonnes of production from over 2,000 workers to just 200. This optimization reflects significant progress in operational efficiency and resource management.
“Changqing Oilfield’s advancements demonstrate our commitment to innovative energy solutions,” said a company spokesperson. “These achievements strengthen our role in meeting the nation’s energy demands sustainably.”
In 2024, Changqing Oilfield accounted for 52.2 percent of China’s total shale oil output, solidifying its position as a leading production hub. The oilfield is projected to produce 3.5 million tonnes annually by 2025, further supporting the country’s energy needs.
The success of Changqing Oilfield highlights the importance of technological innovation in overcoming the challenges of shale oil extraction. Its contributions are expected to play a vital role in the sustainable development of China’s energy resources.
