The article discusses using CO2 and combustion gases to help recover more oil in Russia. They tested this method in the 1980s and found that most of the injected CO2 was recovered within 1-1.5 years. They didn't measure how much CO2 stayed in the reservoir. To understand how CO2 is stored in the ground, they suggest studying how it interacts with oil, water, and rocks during oil displacement.
