  • Method of increasing efficiency in a hydraulic fracturing operation
    Patent number: 8789596
    Abstract: Multiple zones of a subterranean formation penetrated by a multi-zoned completed well may be fractured by pumping into one or more zones an acidizing solution at or above the fracturing pressure of the subterranean formation. After fractures are created or enhanced in the formation, a displacement fluid is pumped into the formation to farther advance the acidizing solution into the fractures.
