14. A process for stimulating subterranean geologic formations, comprising:
(a) providing an injector well extending from a surface to a subterranean geologic formation;
(b) perforating the injector well at a first stimulation zone;
(c) pumping one or more first stimulation fluids at a first rate R1 into the subterranean geologic formation at the first stimulation zone;
(d) perforating the injector well at a target stimulation zone in the subterranean geologic formation, the target stimulation zone spaced apart from and below the first stimulation zone; and
(e) pumping one or more main stimulation fluids at a second rate R2 into the subterranean geologic formation at the target stimulation zone, where R2>R1, wherein the one or more first stimulation fluids and the one or more main stimulation fluids are the same or different, and measuring blocking effect on the one or more main stimulation fluids in the target stimulation zone by the one or more first stimulation fluids in the first stimulation zone.
