| titleOfInvention | Polymer Emulsion for Crude Oil Recovery |
| abstract | The present invention provides polymer emulsions for crude oil recovery. Emulsions of fluidity-controlling polymers can be used to increase the recovery of crude oil from subterranean hydrocarbon-bearing formations. A flooding fluid comprising the polymer emulsion is injected into a well in contact with a subterranean hydrocarbon-bearing formation. The polymers can be temporarily cross-linked and have protected shear degradation and improved injectability into the well; shear resistance can be measured in terms of viscosity loss due to shear, and improved injectability can be measured in terms of filtration of flooding fluids. Over ratio, flow rate and viscosity are measured. |
