Abstract: A method for use of a liquid composition and a liquid composition comprising between about 60 to about 95 volume percent of a water-soluble acid for use in treating subterranean strata, and a base fluid comprising between about 90 to about 60 volume percent of a mixture of at least one eight-carbon aliphatic alcohol and at least one aliphatic alcohol with between one and five carbon atoms and between about 10 to about 40 volume percent of a foaming agent, which when a suitable gas is added will produce a foam suitable for use in stimulating oil and gas wells. Optionally, the base fluid can contain a surfactant comprising a phenoxy polyoxy ethylene alcohol containing 10 to 18 oxyethylene units.
