ABSTRACT:
Betaines containing the pyridine nucleus, some of which are novel per se, are dissolved in sea water or formation water, the concentration of betaine being from 200 to 100,000 ppm, to give a surfactant solution suitable for displacing crude oil from a formation in an enhanced oil recovery process. These betaines have low interfacial tension (against oil), a high tolerance towards divalent metal ions and good temperature stability as compared with betaines previously proposed for enhanced oil recovery.
