Tertary recovery of the Bradford crude oil by micellar solutions, from linear and two-dimensional porous media
Micellar solutions should be tailored for a given crude oil, so that the 2 are miscible over the widest possible range. Lack of miscibility would lead to inefficient displacement. Mobility control at the rear of the slug is critical in determining oil recovery, which increased with the polymer concentration in the buffer. Buffers, consisting of glycerin/water mixtures, showed that even partial mobility control (mobility ratio > 1) can be adequate. Small amounts of isopropyl alcohol in the buffer tended to increase recovery. Oil recovery increased with an increase in the mobility buffer size, however, a 20% buffer is nearly as effective as larger buffers. Oil recovery increases with solvent slug size, however, the recovery ratio decreases, over the range studied. A micellar solution flood, with adequate mobility control, would sweep approx. 60% of the pattern area. Micellar solution floods are relatively insensitive to flood advance rate.
