A hydrocarbon fracturing fluid for fracturing a subterranean formation containing a gelled liquid hydrocarbon made by adding a phosphonic acid ester having the formula:
where R is an alkyl group having from 8 to 24 carbon atoms.
A stoichiometric amount of a polyvalent metal source selected from ferric iron salts and aluminium compounds is also added. Water and an amount of a delayed gel breaker effective to break the gelled liquid hydrocarbon fracturing fluid is added to the hydrocarbon gelled liquid.
