Performance of surfactant blend formulations for controlling gas mobility and foam propagation under reservoir conditions

The use of surfactant is one of the possible solutions to minimize the mobility of gases and improve the sweep efficiency, but the main problem with this process is its stability in the presence of injection water and crude oil under reservoir conditions. In this study, the three types of surfactant...
