Title (EN) WATER SWELLABLE POLYMERS AS LOST CIRCULATION CONTROL AGENTS MATERIAL
(FR) POLYMÈRES GONFLANT DANS L’EAU SERVANT DE MATÉRIAU D’AGENTS DE RÉGULATION DE PERTES DE CIRCULATION
Abstract:
(EN) A sealant composition comprising an inverse emulsion polymer and methods of servicing a wellbore using the same are disclosed. In one embodiment, a method of servicing a wellbore that penetrates a subterranean formation is disclosed. The method comprises placing a sealant composition comprising an inverse emulsion polymer into the wellbore to reduce a loss of fluid to the subterranean formation during placement of the fluid in the wellbore.
(FR) La présente invention concerne une composition de matériau d’étanchéité comprenant un polymère d’émulsion inverse et des procédés destinés à l’entretien d’un puits de forage utilisant cette composition. Dans un mode de réalisation, on utilise un procédé d’entretien d’un puits de forage qui pénètre une formation souterraine. Le procédé consiste à placer une composition de matériau d’étanchéité comprenant un polymère d’émulsion inverse dans le puits de forage afin de réduire une perte de fluide dans la formation souterraine lors du placement du fluide dans le puits de forage.
