... are as the following: Abstract In spite of CO 2 mobility reduction during CO 2 and surfactant solution co-injection, CO 2 -foam flooding in heavy oil reservoirs has relatively poor sweep efficiency due to the high viscosity the oil. Therefore, reducing the oil viscosity is necessary to improve CO 2 -foam sweep...
