Abstract:
A method for treating multiple intervals of one or more subterranean formations intersected by a cased wellbore, said method comprising:a) using a perforating device to perforate at least one interval of said one or more subterranean formations; b) pumping a treating fluid into the perforations created in said at least one interval by said perforating device without removing said perforating device from said wellbore; c) deploying one or more diversion agents in said wellbore to removably block further fluid flow into said perforations; and d) repeating at least steps a) through b) for at least one more interval of said one or more subterranean formations; wherein at some time after step a) and before removably blocking fluid flow into said perforations, said perforating device is moved to a position above said at least one interval perforated in step a).
