Abstract (en)
[origin: EP2940245A1] The invention concerns a method for stimulating a treatment zone near a wellbore (10) area in fluid connection with at least one porous zone (9) of a subterranean formation (1), said method comprising the steps of generating (S1a) at least one electrical discharge in said wellbore at a distance from the at least one porous zone in order to propagate at least one shock wave adapted to fracture said treatment zone (3) and introducing (S2a) a chemical agent within said treatment zone for increasing the permeability of said treatment zone.
