simulation of polymer-surfactant flooding and comparison of adsorption and retention of polymer and surfactant using utchem software

With increasing energy demand and decreasing oil reserves, the importance of eor processes has increased. since a large volume of primary in situ oil remains intact in the reservoir after production, so using eor methods to estimate future energy needs is a must. many flooding projects do not have good displacement efficiency, nor do they have good displacement sweep efficiency. we can modify them by adding chemicals. surfactant - polymer flooding is one of these methods. one of the damages resulting from these methods is the issue of absorption and retention of polymer molecules and surfactant micelles. in this study, we used utchem software to simulate the retention intensity of surfactant and polymer.
