Abstract
(EN)
The present invention relates to improved methods for well stimulation and completion. More particularly, the present invention relates to methods of stimulating and completing well bores while controlling formation sand migration and proppant flowback. One embodiment of the present invention provides a method of stimulating a formation surrounding a well bore comprising the steps of (a) hydraulically fracturing a formation to create or enhance at least one fracture; (b) placing proppant coated with a tackifying agent into the far-well bore area of the fracture; and, (c) placing an agent capable of controlling particulate flowback into the well bore or near-well bore area of the fracture.
(FR)
La présente invention concerne des procédés améliorés de stimulation et de complétion de puits. Plus particulièrement, la présente invention concerne des procédés de stimulation et d'achèvement de trous de puits tout en maîtrisant la migration du sable et le reflux d'agent de soutènement d'une formation. Un mode de réalisation de la présente invention prévoit un procédé de stimulation d'une formation entourant un puits comprenant les étapes consistant: (a) à procéder à la fracturation hydraulique d'une formation pour créer ou améliorer au moins une fracture; (b) à placer un agent de soutènement enrobé d'un agent poissant dans la zone de puits lointaine de la fracture; et (c) à placer un agent capable de contenir le reflux de particules dans le puits ou la zone proche du puits de la fracture.
