Title (EN) FRACTURING A FORMATION WITH MORTAR SLURRY
(FR) FRACTURATION D'UNE FORMATION AVEC UNE SUSPENSION DE MORTIER
Abstract:
(EN) A method to provide a plurality of fractures in a subterranean formation includes providing an essentially horizontal wellbore in the subterranean formation and providing a casing in the essentially horizontal wellbore. The method also includes providing communication between an inside of the casing and the formation and providing a mortar slurry within the casing. The method further includes initiating a fracture from the communication between the inside of the casing and the subterranean formation and propagating the fracture by adding mortar slurry to the wellbore. The pressure forcing propagation of the fracture is essentially provided by a hydrostatic head of mortar slurry in the wellbore.
(FR) Cette invention concerne un procédé de création d'une pluralité de fractures dans une formation souterraine, comprenant la création d'un puits de forage sensiblement horizontal dans la formation souterraine et la mise en place d'un tubage dans le puits de forage sensiblement horizontal. Le procédé comprend en outre l'établissement d'une communication entre un intérieur du tubage et la formation et l'introduction d'une suspension de mortier à l'intérieur du tubage. Le procédé comprend en outre l'initiation d'une fracture à partir de la communication entre l'intérieur du tubage et la formation souterraine et la propagation de la fracture par ajout d'une suspension de mortier dans le puits de forage. La pression qui assure la propagation forcée de la fracture est essentiellement assurée par une charge hydrostatique de la suspension de mortier dans le puits de forage.
