Abstract

This invention relates to improved hydrocarbon gels which find use in the fracturing of petroleum producing formations. In particular it relates to the use of a define class of gelling agents for hydrocarbons which provide excellent results in such fracturing. The gelling agents comprise combinations of selected orthophosphate esters and ferric ammonium citrate or lower alkyl amine derivative thereof. The lower alkyl amine derivatives are referred to as ferric alkylamine citrates.
