Abstract
The invention concerns a method for stimulating a treatment zone near a wellbore area in fluid connection with at least one porous zone of a subterranean formation, 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 and introducing (S2a) a chemical agent within said treatment zone for increasing the permeability of said treatment zone.

A method for stimulating a treatment zone near a wellbore area in fluid connection with at least one porous zone of a subterranean formation, said method comprising the steps of:
- generating 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;
- and
- introducing a chemical agent within said treatment zone for increasing the permeability of said treatment zone.
A stimulating device for recovering hydrocarbons in a wellbore from at least one porous zone of a subterranean formation, said device comprising:
- a electrical discharge generating unit configured for generating 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 a treatment zone near a wellbore area;
- and
- a chemical agent introducing unit configured for introducing a chemical agent within said treatment zone for increasing the permeability of said treatment zone.
