┬áThe injection of CO2 gas into oil reservoirs at high pressure forces the CO2 to mix with oil. This reduces the oil’s viscosity and causes the oil to increase in volume (swell). The result is an increase in the total cumulative volume of oil produced and in the percentage of oil-in-place that is recovered. The decision by a producer whether or not to employ this technique depends on a number of factors, including the geophysical properties of the reservoir, the oil within that reservoir, the cost of applying CO2 EOR, and the revenue received from additional production. The injection of miscible (capable of […]
