The invention provides a method of treating a subterranean formation penetrated by a wellbore, the method comprising the steps of: (a) mixing a particulate and an active material to obtain an at least partially coated particulate, wherein: (i) water forms a contact angle of less than 90 degrees with a surface of the particulate, (ii) the active material is capable of forming a coating on the particulate, (iii) the active material forms a contact angle less than 90 degrees with the particulate, and (iv) water forms a contact angle of greater than 90 degrees with a layer of the active material; (b) mixing the at least partially coated particulate and a carrier fluid to obtain a treatment fluid; and (c) introducing the treatment fluid into the subterranean formation through the wellbore to deposit the at least partially coated particulate into the subterranean formation.
L'invention concerne un procédé de traitement d'une formation souterraine pénétrée par un puits. Ce procédé consiste à: (a) mélanger une matière particulaire et une matière active pour obtenir des particules au moins partiellement enrobées, où: (I) l'eau forme un angle de contact inférieur à 90° avec une surface des particules; (II) la matière active est capable de former un enrobage sur les particules; (III) la matière active forme un angle de contact inférieur à 90° avec les particules; et (IV) l'eau forme un angle de contact supérieur à 90° avec une couche de la matière active; (b) mélanger les particules au moins partiellement enrobées avec un fluide porteur pour obtenir un fluide de traitement; et (c) introduire le fluide de traitement dans la formation souterraine à travers le puits pour déposer les particules au moins partiellement enrobées dans la formation souterraine.
