Title
(EN) METHODS TO CREATE HIGH CONDUCTIVITY FRACTURES THAT CONNECT HYDRAULIC FRACTURE NETWORKS IN A WELL
(FR) PROCÉDÉS POUR CRÉER DES FRACTURES À HAUTE CONDUCTIVITÉ QUI RACCORDENT DES RÉSEAUX DE FRACTURE HYDRAULIQUE DANS UN PUITS
Abstract
(EN)
The application discloses a method of treating a subterranean formation of a well bore, that provides a first treatment fluid; pumps the first treatment fluid to initiate a network of low conductivity fractures in the subterranean formation; provides a second treatment fluid comprising a second carrier fluid, a particulate blend including a first amount of particulates having a first average particle size between about 100 and 2000 µm and a second amount of particulates having a second average particle size between about three and twenty times smaller than the first average particle size, such that a packed volume fraction of the particulate blend exceeds 0.74; and pumps the second treatment fluid to initiate at least one high conductivity fracture in the subterranean formation. The high conductivity fracture has a conductivity higher than the average of conductivity of the low conductivity fractures and connects the network of the low conductivity fractures.

La présente invention concerne un procédé de traitement d'une formation souterraine d'un forage de puits, qui fournit un premier fluide de traitement; pompe le premier fluide de traitement pour commencer un réseau de fractures à basse conductivité dans la formation souterraine; fournit un second fluide de traitement qui comprend un second fluide transporteur, un mélange particulaire qui comprend une première quantité de particules en suspension qui possède une première taille moyenne des particules entre environ 100 et 2 000 µm et une seconde quantité de particules en suspension qui possède une seconde taille moyenne des particules entre environ trois et vingt fois inférieure à celle de la première taille moyenne des particules, de sorte qu'une fraction de volume tassé du mélange particulaire dépasse 0,74; et pompe le second fluide de traitement pour commencer au moins une fracture à haute conductivité dans la formation souterraine. La fracture à haute conductivité possède une conductivité supérieure à la moyenne de conductivité des fractures à basse conductivité et raccorde le réseau des fractures à basse conductivité.
