Abstract
L'invention porte sur un procédé de disposition d'un mélange de particules dans une fracture formée dans une formation souterraine à partir d'un puits de forage, lequel procédé met en œuvre l'injection à travers le puits de forage d'un premier fluide de traitement pour déclencher ou propager la fracture dans la formation souterraine ; le premier fluide de traitement comprenant un coulis de mélange de particules ; le mélange de particules comprenant au moins une première quantité de particules ayant une première taille de particules moyenne entre environ 100 et 5000 micromètres et au moins une seconde quantité de particules ayant une seconde taille de particules moyenne entre environ trois et vingt fois plus petite que la première taille de particules moyenne ; l'injection à travers le puits de forage d'un second fluide de traitement ayant une viscosité différente de celle du premier fluide de traitement ; et la formation avec le coulis de mélange de particules d'une pluralité d'amas riches en particules mutuellement espacés par des régions sans particule formant des canaux ouverts.
