Beschreibung
Zusammenfassung:	The present invention generally relates to a low residue hydraulic fracturing fluid which comprises an aqueous fluid and at least one polymeric gelling agent, wherein said polymeric gelling agent comprises at least one crosslinked, modified starch. The invention also relates to a method of fracturing a subterranean formation through the use of the aforementioned fracturing fluid. L'invention concerne en général un fluide de fracturation hydraulique générant peu de résidus, qui comprend un fluide aqueux et au moins un agent de gélifiant polymère, ledit agent de gélifiant polymère comprenant au moins de l'amidon modifié réticulé. L'invention concerne également un procédé de fracturation de formation souterraine via l'utilisation du fluide de fracturation précité.
