METHOD OF ENHANCING THE COMPLEXITY OF A FRACTURE NETWORK WITHIN A SUBTERRANEAN FORMATION

摘要

The complexity of a fracture network within a subterranean formation may be enhanced by pumping a high breakdown pressure fluid followed by a low breakdown pressure fluid into the formation. The method increases the Stimulated Reservoir Volume (SRV) of the formation and provides for a network of ancillary fractures within the formation.
