Displacement tests to date of oil field core with alkaline solutions at reservoir temperature show low tertiary oil recovery. Inadequate mobility control is singled out as the reason for such poor recovery. To test the validity of this reasoning, a laboratory study was undertaken in which a high heat resistant polymer was used as the mobility control agent in a hot alkaline solution recovery technique. A combination of varying concentration and volumes of the polymer solution was injected into the sandpack which was then flooded with hot sodium hydroxide solution. The range of polymer concentration was between 0.0% and 3.0%, while the volume varied between 0.0 pore volume and 1.7 pore volume. It was observed that polymer injection actually did improve recovery substantially and that there is an optimum concentration and slug size of polymer for a particular reservoir. Higher concentrations of pore volumes injected did not improve recovery significantly.
