The present invention relates to aqueous oilfield treatment fluids containing a gas component and fibers, wherein the fluids may further include a viscosifying agent and/or proppant. The fluids have good proppant suspension and transport properties as well as excellent gas phase stability. Use of fluids comprising an aqueous medium, a gas component, viscosifying agent, and fibers for hydraulically fracturing a subterranean formation, cleanup operations, and gravel packing a wellbore, are also disclosed.
L'invention concerne des fluides de traitement aqueux pétrolifères qui contiennent un composant gazeux et des fibres, ces fluides pouvant également contenir un améliorant d'indice de viscosité et/ou un agent de soutènement. Par ailleurs, ces fluides présentent de bonnes propriétés de transport et de suspension de l'agent de soutènement ainsi qu'une excellente stabilité de la phase gazeuse. De plus, l'invention concerne l'utilisation de fluides contenant un support aqueux, un composant gazeux, un améliorant d'indice de viscosité, ainsi que des fibres, en vue de fracturer hydrauliquement une formation souterraine, exécuter des opérations de dépollution et gravillonner des crépines de puits.
