A method for controlling the rheology of aqueous systems, particularly for those intended for underground use, includes injecting an aqueous fluid containing a surfactant gelling agent into the system. The surfactant gelling agents are, for example, fatty aliphatic amidoamine oxides, salts of an alkoxylated monoamine with an aromatic dicarboxylic acid, and salts of an alkyldiamine with an aromatic dicarboxylic acid. The surfactant gelling agents can be adsorbed onto particulate supports to facilitate delivery of the gelling agent. The additives may be incorporated in the viscoelastic fluid to tailor its use in hydraulic fluids, drilling muds, fracture fluids, and in applications such as permeability modification, gravel packing, cementing, and the like.

La présente invention concerne un procédé permettant de réguler la rhéologie de systèmes aqueux, en particulier ceux qui sont destinés à un usage souterrain, lequel procédé est caractérisé en ce que l'on injecte un fluide aqueux contenant un agent gélifiant tensio-actif dans le système. Les agents gélifiants tensio-actifs sont constitués, par exemple, par des oxydes d'amidoamine aliphatique grasse, des sels d'une monoamine alcoxylée avec un acide dicarboxylique aromatique, et des sels d'une alkyldiamine avec un acide dicarboxylique aromatique. Les agents gélifiants tensio-actifs peuvent être adsorbés sur des supports particulaires qui facilitente leur délivrance. Les additifs peuvent être incorporés dans le fluide viscoélastique afin de l'adapter à une utilisation dans les fluides hydrauliques, les boues de forage, les liquides de fracturation, et dans des applications telles que, entre autres, la modification de perméabilité, le gravillonnage de crépines et la cimentation.
