Title (EN) METHODS FOR DIVERSION AND CONTROLLING FLUID-LOSS USING FORMATE BRINE COMPOSITIONS
(FR) PROCÉDÉS DE DÉRIVATION ET DE COMMANDE DE PERTE DE FLUIDE À L'AIDE DE COMPOSITIONS DE SAUMURE DE FORMIATE
Abstract:
(EN) Methods of temporarily blocking zones of a subterranean formation for diversion, isolation, and fluid-loss control are provided. The method of diverting a fluid includes introducing a treatment fluid comprising a formate brine, xanthan gum, and a cross-linking agent into the formation; allowing the treatment fluid to set into a gel in perforations in a first zone of the formation to block the perforations in the first zone; introducing a stimulation fluid into the formation; and diverting the stimulation fluid away from the perforations in the first zone to perforations in a second zone of the formation.
(FR) La présente invention concerne des procédés de blocage temporaire de zones d'une formation souterraine pour une dérivation, une isolation et une commande de perte de fluide. Le procédé de dérivation d'un fluide consiste à introduire un fluide de traitement, qui comprend une saumure de formiate, de la gomme de xanthane et un agent de réticulation, dans la formation ; laisser le fluide de traitement se solidifier pour former un gel dans des perforations dans une première zone de la formation pour bloquer les perforations dans la première zone ; introduire un fluide de stimulation dans la formation ; et dériver le fluide de stimulation pour l'éloigner des perforations dans la première zone et l'amener vers des perforations dans une seconde zone de la formation.
