A surfactant was added to the end of a waterflood recovery and gave an additional oil recovery of about 9 percent over the amount projected for the waterflood. The reservoir was Bartlesville sand, Batesville pool, Toronto District of Woodson County, Kansas (porosity 16.5 to 21 percent, 55 md average permeability, crude oil gravity 40/sup 0/ API, crude oil viscosity 1 cp at 80/sup 0/F). The surfactant, Pluronic L64 (a nonionic copolymer of ethylene and propylene oxide) had a very low order of adsorption, which was not affected by the addition of salt to the solution. The flood water, Kansas City lime brine contained 14,000 ppM divalent cations.
