Title
(EN) SELF-SUSPENDING MATERILAL FOR DIVERSION APPLICATIONS
(FR) MATÉRIAU À SUSPENSION AUTOMATIQUE POUR APPLICATIONS DE DIVERSION
Abstract
(EN)
A method of servicing a wellbore in a subterranean formation including combining diverter material and aqueous base fluid to form a diverter fluid, wherein the diverter material is self-suspending and comprises psyllium husk particulates; introducing the diverter fluid into the wellbore; and allowing the diverter material to form a diverter plug in the wellbore or the formation. A method of servicing a weiibore in a subterranean formation including combining diverter material including psyllium husk particulates and a first wellbore servicing fluid; introducing the first wellbore servicing fluid into the wellbore; allowing the diverter material to form a diverter plug in a first location in the wellbore or the formation; diverting the flow of a second wellbore servicing fluid to a second location in the wellbore of formation; and removing the diverter plug, wherein the first and second wellbore servicing fluids may be the same or different.

L'invention concerne un procédé d'entretien d'un puits de forage dans une formation souterraine consistant à combiner un matériau de diversion et un fluide de base aqueux pour former un fluide de diversion, le matériau de diversion étant à suspension automatique et comprenant des particules d'enveloppe de psyllium ; à introduire le fluide de diversion dans le puits de forage ; et à permettre au matériau de diversion de former un bouchon de dérivation dans le puits de forage ou dans la formation. L'invention concerne un procédé d'entretien d'un puits de forage dans une formation souterraine consistant à combiner un matériau de diversion comprenant des particules d'enveloppe de psyllium et un premier fluide d'entretien de puits de forage ; à introduire le premier fluide d'entretien de puits de forage dans le puits de forage ; à permettre au matériau de diversion de former un bouchon de dérivation dans un premier emplacement dans le puits de forage ou dans la formation ; à dériver l'écoulement d'un second fluide d'entretien de puits de forage vers un second emplacement dans le puits de forage de la formation ; et à retirer le bouchon de dérivation, les premier et second fluides d'entretien de puits de forage pouvant être identiques ou différents.
