METHOD OF FRACTURING USING ULTRA LIGHTWEIGHT PROPPANT SUSPENSIONS AND GASEOUS STREAMS

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...

Summary: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. Dans un procédé de fracturation hydraulique fracturant une formation souterraine porteuse d'hydrocarbure, une étape d'agent de soutènement est introduite dans la fracture qui comprend un fluide gazeux et un agent de soutènement ultra léger suspendu dans un fluide aqueux viscosifié. Le fluide gazeux de l'étape d'agent de soutènement contient au moins environ 90 pour cent en volume de la combinaison de fluide gazeux et de fluide aqueux. Un fluide tampon peut être d'abord introduit dans la formation, le fluide tampon renfermant un fluide gazeux et, facultativement, un fluide aqueux. Le fluide gazeux du mélange de fluide tampon renferme habituellement au moins 70 pour cent en volume du mélange.
