Enhanced oil recovery using mobility control crosslinked polymers

Emulsions of mobility control polymers can be used to increase recovery of crude oil from a subterranean hydrocarbon-containing formation. A flooding fluid comprising the polymer emulsions are injected into a well that is in contact with the subterranean hydrocarbon-containing formation. The polymers can be temporarily cross-linked via hydrolyzable crosslinking moieties derived from a multifunctional hydrazide, a multifunctional amine, a multifunctional hydroxylamine, or a combination thereof and have improved injectivity into the well; the improved injectivity can be measured in terms of the flooding fluid's filter ratio, flow rate, and viscosity.
