Investigation of Temperature and Hydrolyzed Polyacrylamide Polymer on Adsorption Density of the Triton X-100 Surfactant in Carbonate Rocks

Nowadays, the natural energy of the reservoir is not capable of producing remained oil in reservoirs due to the drop in the bottomhole pressure in oil reservoirs. Hence, oil industry professionals are always searching for new ways to recover remained oil in reservoirs. Chemical injection has been used extensively for EOR purposes in recent decades. But this method has always been subject to limitations. The waste of surfactant and polymer during injection operations in reservoirs is considered as the most important issue in the feasibility of chemical injection operations. Many efforts have been made to reduce the absorption of surfactants on rock surface for the economic operation. Adding polymer to injectable chemicals is used as the most practical method, due to a better control of the water-oil mobility ratio and also the impact on the absorption of surfactants in different ways. In this study, the effect of temperature on the adsorption of chemical surfactant, Triton X100, has been investigated. In addition, the effect of hydrolyzed polyacrylamide polymer on the absorption of this surfactant has also been evaluated.
