Abstract (en)
[origin: WO2018007305A1] The invention concerns a method for forming a stabilised foam suitable, in particular, for enhanced oil recovery, by expanding a foaming composition by means of at least one gas and/or steam, in which said foaming composition comprises, within an aqueous medium: - a surfactant or a mixture of surfactants suitable for forming a foam, under the effect of the introduction of the gas and/or the steam; and - clay particles. The foam formed is advantageously subjected to a heat treatment step, subsequent or simultaneous to the formation of same, at a temperature higher than the thermolysis temperature of said surfactant or mixture of surfactants.
