Abstract
On constate une augmentation des longueurs étayées efficaces dans des procédés par fracturation hydraulique au moyen d'agents de soutènement ultralégers. Les agents de soutènement ultralégers présentent une densité inférieure ou égale à 2,45 g/cc et peuvent être utilisés en tant que mélange dans un premier étage d'agent de soutènement où au moins un agent de soutènement est ultraléger. De manière alternative, des étages d'agent de soutènement séquentiels peuvent être introduits dans la formation où au moins un des étages d'agent de soutènement comprend un agent de soutènement ultraléger et où au moins une des conditions suivantes prévaut : (i.) la densité différentielle entre le premier étage d'agent de soutènement et le deuxième étage d'agent de soutènement est plus élevée ou égale à 0,2 g/cc, (ii.) le premier étage d'agent de soutènement et le deuxième étage d'agent de soutènement comprennent un agent de soutènement ultraléger, (iii.) le taux d'injection du deuxième agent de soutènement dans la fracture est différent du taux d'injection du premier étage de soutènement ou (iv.) la taille particulaire du deuxième étage d'agent de soutènement est différente de la taille particulaire du premier étage d'agent de soutènement.
