C Chemical flooding (chemical injection) is one type of method draining oiladvanced stage (EOR) with adding a chemicals substances into water injection to raise oil revenue so will raise sweeping efficiency or lowering the saturation of the remaining oil who is left in a reservoir.The variables were analysed of the physical properties of fluid among othersthe viscosity, the density and voltage interface. The results of the measurement of the density and viscosity from the surfactant and brine show increasing the concentration of the density and the viscosity .This is shown of the results of the measurement of the density and thesurfactant viscosity that produces the value of the smallest in the concentration of 0.1 % which is 1,031 gr / cc , 0,615cp and the largest of 0.5 % which is 1,059 gr / cc , 1,083cp .The results of the measurement of voltage interface shows a continued to decline with increasing concentration .This is shown of the results of the measurement of voltage interface produce the greatest value in the concentration of 0.1 % which is 49 dyne , and the smallest value in the concentration of 0.5 % which is 47,06 dyne.
