Abstract: The invention relates to a collecting device for collecting debris of deposits while said deposits are being removed from a wellbore wall or an equipment arranged in a wellbore of a subterranean formation in order to improve the recovery of formation fluids and/or gases, said collecting device being configured for being attached to a cleaning device, said cleaning device being configured for removing deposits from a wellbore wall or an equipment arranged in a wellbore. The collecting device comprises a deflector, configured for deflecting falling debris of deposits while said deposits are being removed from said wellbore wall or said equipment, and a debris storing module, connected to said deflector for collecting and storing debris deflected by said deflector.

Abstract: The invention relates to an electrical discharge generating device for cleaning an equipment arranged in a wellbore of a subterranean formation in order to improve the recovery of formation fluids and/or gases, said electrical discharge generating device comprising a discharge unit for generating at least one electrical discharge that propagates at least one shock wave for cleaning from said equipment, wherein said electrical discharge generating device further comprises a retaining module configured for retaining a volume of liquid in order to immerse the discharge unit.

Abstract: Aspects of the present disclosure include a system and a method for sealing at least one opening of a wellbore equipment arranged in a wellbore of a subterranean formation in order to improve the recovery of formation fluids and/or gases. The method includes the steps of positioning a metal patch between the wellbore equipment and a shock wave generation device. The metal patch faces the at least one opening to be sealed and the method further including generating, using a shock wave generation device, at least one electrical discharge into said wellbore in order to propagate toward said metal patch at least one shock wave adapted to deform and fix the metal patch onto the wellbore equipment, sealing therefore the at least one opening.

Abstract: Systems and methods for removing deposits from a component of a formation fluid and/or gas transportation tubing string. The disclosed systems and methods generate at least one shock wave into a shock wave transmitting liquid into the transportation tubing string nearby to the component and propagate the at least one shock wave toward the component for removing deposits from the component.

Abstract: The invention concerns a method for cleaning control particles in a wellbore of a subterranean formation to improve the recovery of formation fluids and/or gases, said wellbore comprising a wall defining a borehole, at least one control equipment arranged into said borehole and a plurality of control particles arranged between said control equipment and said wall, said method comprising the steps of generating at least one shock wave nearby said control equipment and propagating said at least one shock wave through said control equipment toward said control particles for cleaning said control particles.

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.
