In a 2022 research article, CO2 injection consistently outperformed the conventional waterflooding in Enhanced Oil Recovery (EOR). Injection of CO2 presents an effective enhanced oil recovery (EOR) approach for several reasons such as low CO2-miscibility pressure, CO2 sequestration, oil swelling, and viscosity reduction. On average, each enhanced oil recovery (EOR) operation could store about 7,928 tons of CO2, reducing environmental impact. CO2 injection into the water zone proved highly effective, increasing oil recovery to about 68-70%. Using the Computer Modelling Group software to investigate different injection scenarios, injecting CO2 with vertical wells maximised oil recovery, achieving up to 73% of the original oil-in-place (OOIP) in the reservoir. Studies show that the captured CO2 stays in the oil reservoir permanently when it is injected in this way. And if enough CO2 is injected during oil production, it might make up for the combustion emissions of the produced oil, or even result in overall negative emissions. Carbon capture is today the cheapest way to deal with emissions from heavy industries that require combustion. It has the advantage that it can also capture CO2 emissions that come from the process itself, rather than from fuel combustion,
