Title (EN) METHODS FOR WELLBORE STRENGTHENING AND CONTROLLING FLUID CIRCULATION LOSS
(FR) PROCÉDÉS PERMETTANT DE RENFORCER UN PUITS DE FORAGE ET DE RÉGULER LA PERTE DE CIRCULATION DE FLUIDE
Abstract:
(EN) A sealant composition and methods for using the same are disclosed. In an embodiment, a method of servicing a wellbore in contact with a subterranean formation is disclosed. The method comprises placing a sealing agent and a nonaqueous carrier fluid in the wellbore. The method further comprises placing a nonaqueous activating fluid in the wellbore. In addition, the method comprises contacting the sealing agent with the nonaqueous activating fluid to form a sealant composition.
(FR) La présente invention concerne une composition de scellant et des procédés utilisant cette composition. Dans un mode de réalisation, on utilise un procédé permettant d’entretenir un puits de forage communiquant avec une formation souterraine. Le procédé consiste à placer un agent d’étanchéité et un fluide porteur non aqueux dans le puits de forage. Le procédé consiste également à placer un fluide d’activation non aqueux dans le puits de forage. En outre, le procédé consiste à mettre en contact l’agent d’étanchéité avec le fluide d’activation non aqueux afin d’obtenir une composition de scellant.
