Patent
·
OSTI ID:6163804
An improved method is described of fracture acidizing a producing zone in a subterranean formation comprising the steps of: (a) creating one or more fractures in said zone; (b) causing said fractures to close; (c) injecting acid into and through said closed fractures so that flow channels are formed therein; (d) extending said one or more fractures in said zone; (e) causing said fractures to close; (f) injecting acid through said flow channels previously formed and through the portions of said fractures extended in accordance with step (d) while said fractures are closed so that flow channels are formed in said extended portions of said fractures; and (g) repeating steps (d), (e) and (f) until said fractures having flow channels formed therein extend desired distances in said zone.
