This invention relates to improved hydrocarbon gels finding use in the fracturing of formations which produce petroleum and other hydrocarbons. The gelling agents comprise combinations of ferric salts, selected orthophosphate esters, a low molecular weight amine such as triethonolamine or triethylamine, and a surfactant.
