ABSTRACT:
A method of treating a carbonate-containing subterranean formation to increase the production of hydrocarbons therefrom. The formation is contacted with an aqueous solution of one or more of certain anionic aminophosphonate compounds whereby the composition is caused to be absorbed onto the solid surfaces present in the subterranean limestone-containing formation and substantially reduces the tendency of such surfaces from becoming water or hydrocarbon wet.
