    摘要： A process for drilling cavities in subterranean formations includes a step of removal of the drill cuttings using an aqueous fluid in the form of a foam, obtained by mixing: an aqueous composition (Ci) including, per 100% by weight: from 0.5% by weight to 25% by weight of a compound of formula (I): R1—C(O)—NH—CH(COOM)-(CH2)n—COOM′ (I) in which n represents an integer equal to 1 or 2, R1 represents a linear or branched, saturated or unsaturated aliphatic hydrocarbon-based radical including from eight to eighteen carbon atoms, M represents a monovalent cation and M′, which is identical to or different from M, represents a hydrogen atom or a monovalent cation; or of a mixture of compounds of formula (I), and from 75% to 99.5% by weight of water, with a gas or a mixture of gases, chosen from air, nitrogen or carbon dioxide.
