Jones, S C

Slugs of micellar solutions, displaced by thickened water, were evaluated in Berea sandstone cores, previously waterflooded to residual oil saturation. The performance and flow behavior of one of these slugs is described. Flooding performance is remarkable: A 1% pore volume slug recovered 59% of the tertiary oil-in-place, while a 5% pore volume slug recovered 100% of the crude oil from a 4-ft long by 2-in. diam. consolidated core. High displacement efficiencies are maintained by avoiding unfavorable mobility ratios. The displacements do not suffer from the high degree of viscous fingering associated with most miscible floods. Equations are presented which describes several aspects of the flow behavior of the Maraflood oil recovery process. These include oil breakthrough, oil cut during production of the stabilized oil bank, breakthrough of banked water and the resulting decreased fractional flow of oil, fluid mobilities, etc. Breakthroughs, calculated from the equations, are compared with experimental data.
