Carbon capture tech makes oilfield go greener

Editor's Note: As protection of the planet's flora, fauna and resources becomes increasingly important, China Daily is publishing a series of stories to illustrate the country's commitment to safeguarding the natural world. Ma Chenglong, head of the sixth oil extraction area in Liaohe Oilfield and the person-in-charge of the CCUS cyclic injection station, said that since the trial operation of the first carbon storage facility, the 229 Block CCUS cyclic injection station, in Liaohe Oilfield in December, nearly 50,000 metric tons of liquid carbon dioxide isolated from petroleum production emissions have been injected underground. "This is the only carbon storage facility in Liaohe Oilfield, and by 2026, it will be able to store 100,000 tons of carbon dioxide," Liang Fei, a senior engineer at the research institute, said. "The total carbon dioxide storage capacity can reach 2.36 million tons, which is equivalent to the function of reducing carbon dioxide emissions by planting a forest of 950,000 trees in an area of 10,000 mu." The construction of this carbon storage facility is an important project for Liaohe Oilfield to help reach national dual carbon targets and achieve green, low-carbon and clean development.
