Title (EN) METHOD OF FRACTURING USING ULTRA LIGHTWEIGHT PROPPANT SUSPENSIONS AND GASEOUS STREAMS
(FR) PROCÉDÉ DE FRACTURATION PAR UTILISATION DE SUSPENSIONS D'AGENT DE SOUTÈNEMENT ULTRALÉGER ET DE FLUX GAZEUX
Abstract: front page image
(EN)In a method of hydraulically fracturing a hydrocarbon-bearing subterranean formation, a proppant stage is introduced into the fracture which contains a gaseous fluid and an ultra lightweight proppant suspended in a viscosified aqueous fluid. The gaseous fluid of the proppant stage contains at least about 90 volume percent of the combination of gaseous fluid and aqueous fluid. A pad fluid may first be introduced into the formation, the pad fluid containing a gaseous fluid and, optionally, an aqueous fluid. The gaseous fluid of the pad fluid mixture typically contains at least 70 volume percent of the mixture.
(FR)La présente invention concerne un procédé de fracturation hydraulique d'une formation souterraine pétrolifère comprenant l'introduction d'une phase d'agent de soutènement dans la fracture qui contient un fluide gazeux et un agent de fracturation ultraléger en suspension dans un fluide aqueux rendu visqueux. Le fluide gazeux de la phase d'agent de soutènement contient au moins environ 90 % par volume de la combinaison de fluide gazeux et de fluide aqueux. Un fluide tampon peut d'abord être introduit dans la formation, le fluide tampon contenant un fluide gazeux et, éventuellement, un fluide aqueux. Le fluide gazeux du mélange de fluide tampon contient typiquement au moins 70 % par volume du mélange.
