Effect of Sand Grain on Adsorption of Xanthan Gum and Polyacrylamide

Abstract Polymer flooding is an Enhanced oil recovery (EOR) method using chemicals, such as xanthan gum and polyacrylamide which are widely used in the field. can improve mobility of injection fluid, but reservoir polymer has interaction with sand known adsorption causes some to be bound surface pore sand, so that it impact on ineffectiveness injection. The purpose this study want determine compare effect grain solutions. Based experiment results, was found increase proportional concentration. From two polymers used, showed lower than polyacrylamide. grain, occurs greater size for large small.
