摘要： A process for recovering heavy oil with the steps of: a) injecting into one or more injection wells an aqueous injection fluid containing one or more surfactants designed to form a pseudo-emulsion between the injection fluid and the heavy oil, and, b) recovering the oil from one or more producing wells. The process does not require the addition of outside mechanical or thermal energy or solvents to recover the heavy oil and does not form emulsions between the injection fluid and the heavy oil that may be difficult to break when brought to the surface or may cause increased viscosity and injectivity problems within the reservoir.

摘要： Sulfonated betaines amine oxides, and sultaines are made by the reaction of the corresponding unsaturated betaines or sultaines. These are formulated into injection fluids suitable for the recovery of residual oil from subterranean reservoirs. The sulfonated betaines, amine oxides, and sultaines exhibit lower adsorption onto reservoir rock compared to their corresponding unsulfonated betaines, amine oxides, and sultaines. They can be used in applications where their respective amphoteric surfactants are currently used such as personal care, mining, improved oil recovery (IOR), oil field drilling, fracturing, acidizing, foaming, oil field stimulation, and agricultural formulations.
