CO2 INJECTION

CO2 Injection is an "enhanced oil recovery" (EOR) technology that represents the greenest way for recovering America's oil that was, at one time thought to be unrecoverable... CO2 Injection, and "CO2 Flooding," have been heralded as the greenest way to recover stranded oil as carbon dioxide frees the stranded oil easily and affordably - and after the oil has been recovered, the co2 is "trapped" in the reservoir, in a solution called "carbon capture and sequestration." In CO2 injection, carbon dioxide, under pressure, is injected between oil wells to freeing the stranded oil. At one time, water was injected to free the stranded oil, but the water mixed with the oil and the recovered liquid quickly became mostly water, that had to be separated from the oil. CO2 is a superior agent in recovering stranded oil as the CO2 naturally reduces the surface tension that traps the liquid oil to in the oil reservoir. When the oil is recovered from the production well, CO2 is also produced, but is..
