CA 2595073

The present invention relates to novel aqueous wellbore treatment fluids containing a gas component, a heteropolysaccharide, an electrolyte, and a surfactant, wherein the fluids may further include an organoamino compound. The fluids exhibit good rheological properties at elevated temperatures. Methods of use of fluids comprising at least an aqueous medium, a gas component, a heteropolysaccharide and a surfactant for hydraulically fracturing, well cleanup and gravel packing operations, are also disclosed.

L'invention concerne des fluides aqueux de traitement de trou de forage qui contiennent un élément gazeux, un hétéropolysaccharide, un électrolyte, et un tensioactif, mais aussi éventuellement un composé organoamino. Ces fluides ont de bonnes propriétés rhéologiques à des températures élevées. On décrit aussi des procédés d'utilisation de fluides qui comprennent au moins un milieu aqueux, un élément gazeux, un hétéropolysaccharide et un tensioactif, pour la fracturation hydraulique, le nettoyage de puits et le gravillonnage des crépines.
