A method for suppressing fluid communication to or from a wellbore in a subsurface formation, which method comprises providing a well fluid which comprises solid particles in a carrying fluid, which solid particles include a reactive polymer; introducing the well fluid into the wellbore so that carrier fluid passes through an interface between the wellbore and its surroundings, wherein particles are accumulated at the interface; and allowing the polymer to form a solid plug suppressing fluid communication through the interface; and a well fluid for use in a wellbore, which well fluid comprises solid particles in a carrying fluid, which solid particles include a reactive polymer.

Procédé de suppression de la communication fluidique vers et à partir d'un puits de forage dans une formation souterraine, consistant à prévoir un fluide de forage comportant des particules solides dans un fluide véhicule, lesdites particules solides comprenant un polymère réactif ; à introduire le fluide de forage dans le puits de forage de telle manière que le fluide véhicule traverse une interface entre le puits de forage et son environnement, les particules étant accumulées au niveau de l'interface ; et à permettre au polymère de former un bouchon solide qui supprime toute communication fluidique au travers de l'interface ; et fluide véhicule utilisable dans un puits de forage, ce fluide comportant des particules solides dans un fluide véhicule, et lesdites particules solides comprenant un polymère réactif.
