Method for sealing an opening of a wellbore equipment

A system comprising:

• a shock wave generation device for sealing at least one opening of a wellbore equipment arranged in a wellbore of a subterranean formation, the shock wave generation device comprising a chamber that is at least partially filled with a shock wave transmitting liquid and a membrane delimiting, at least partially, the chamber, the membrane having a length, made of a fluoro elastomer and having a relative elongation that is at least 150% of the length when operable between the temperatures of −35° C. and 250° C.;
• the wellbore equipment comprising at least one opening to be sealed arranged in the wellbore of the subterranean formation;
• a circular plate arranged in the wellbore, between the shock wave generation device and the wellbore equipment, and facing the at least one opening to be sealed;
• the shock wave generation device comprising a discharge unit configured for generating at least one electrical discharge that propagates at least one shock wave into the shock wave transmitting liquid through the membrane toward the plate, the at least one shock wave being adapted to deform and fix the plate onto the wellbore equipment to seal the at least one opening.
