ABSTRACT:
The invention consists of a new process for selectively treating a subterranean formation without affecting or being effected by the two adjacent zones (above and below).
Using the invented process, the treatment fluid is injected into the formation to be treated F, at the same time as two protection fluids, whether the same or different, are injected into the two adjacent zones (above [ZS] and below [ZI]).
The process can be applied even in the presence of fractures, gravel-pack and their zones.
