ABSTRACT:
This specification is directed to a method of producing oil from an oil-containing subterranean formation by a caustic waterflood. Oil containing carboxylic acids is passed through an ion-exchange resin to selectively remove the carboxylic acids therefrom. The removed carboxylic acids are injected into the formation in conjunction with the caustic waterflood to enhance the production of oil from the formation.
