n: a method of improved recovery in which alkaline chemicals such as sodium hydroxide are injected during a water flood or combined with polymer flooding. The chemicals react with the natural acid present in certain crude oils to form surfactants within the reservoir. The surfactants enable the water to move additional quantities of oil from the depleted reservoir. Compare chemical flooding, polymer flooding, water flooding.

linear or ring compounds with a CO-NH2 attachment. Common in surfactants.

a surfactant whose charge is dependent on another variable, normally pH.

n: The active agent which has alcaline base and acid base.

a negatively charged surfactant. Normally water wets sands.

n: A kind of surface acting agent. It can produce hydrophobic negative ion.

a positively charged surfactant, normally oil wets sands.

n: Refers to the surfactants that cation is the active part after the surfactants breakdown in the water.

a common zeolite mineral with sensitivity to some surfactants.

n: the quality of being corrosive. cosurfactant n: a surfactant, generally an alcohol, added to a micellar solution to adjust the viscosity of the solution, maintain its stability, and prevent adsorption of the main surfactant by reservoir rock.
