Title
(EN) METHODS AND COMPOSITIONS FOR MITIGATING FLUID LOSS FROM WELL BALLOONING
(FR) PROCÉDÉS ET COMPOSITIONS D'ATTÉNUATION DE PERTE DE FLUIDE À PARTIR D'UN BALLONNEMENT DE PUITS
Abstract
(EN) A method of servicing a wellbore in a formation comprising circulating in the wellbore a wellbore servicing fluid wherein an equivalent circulating density of the wellbore servicing fluid is from about 1% to about 15% greater than a fracture pressure of the formation, and introducing to the wellbore a balloon-inhibiting tunable spacer (BITS) fluid wherein at least about 1 wt.% of the BITS fluid is retained by the formation.
(FR) L'invention concerne un procédé d'entretien d'un puits de forage dans une formation comprenant la circulation dans le puits de forage d'un fluide d'entretien de puits de forage, une densité de circulation équivalente du fluide d'entretien de puits de forage étant d'environ 1 % à environ 15 % supérieure à une pression de fracture de la formation, et l'introduction dans le puits de forage d'un fluide de régleur d'écartement accordable inhibant les ballons (BITS), au moins environ 1 % en poids du fluide BITS étant retenu par la formation.
