Abstract

See full text

A composition useful for crosslinking phosphate esters in hydrocarbon gels used in formation fracturing performs especially well in cold temperatures, such as temperatures lower than (−)20° C. Methods of making the crosslinking composition and the gel are described; also methods of fracturing subterranean formations. Specific forms of ferric sulfate and ferric ammonium citrate are useful as ingredients of the crosslinking composition.
