Abstract
A wellbore stimulation operation method includes conveying a downhole assembly into a wellbore. The downhole assembly includes one or more perforating guns and a pressure wave resonator. The perforating guns are axially aligned with a production zone and fired to create a plurality of perforations in the production zone. The pressure wave resonator is axially aligned with the perforations and actuated to emit pressure waves that propagate radially outward and into the production zone. The pressure waves help remove debris from the perforations.

A wellbore stimulation operation method, comprising:
- conveying a downhole assembly into a wellbore including a production zone, the downhole assembly including one or more perforating guns and a pressure wave resonator;
- axially aligning the one or more perforating guns with the production zone;
- triggering operation of the one or more perforating guns and thereby creating a plurality of perforations in the production zone;
- axially aligning the pressure wave resonator with the plurality of perforations;
- actuating the pressure wave resonator and thereby emitting pressure waves that propagate radially outward and into the production zone;
- and
- removing debris from the plurality of perforations with the pressure waves.
A wellbore stimulation operation method, comprising:
- hydraulically fracturing a production zone of a wellbore and thereby creating micro-fractures in the production zone;
- reducing a fluid pressure within the wellbore and subsequently conveying a downhole assembly including a pressure wave resonator into the wellbore;
- axially aligning the pressure wave resonator with the production zone;
- actuating the pressure wave resonator and thereby emitting pressure waves that propagate radially outward and into the micro-fractures;
- and
- removing debris from the micro-fractures with the pressure waves.
A downhole assembly for undertaking a wellbore stimulation operation, comprising:
- one or more perforating guns;
- and
- a pressure wave resonator operatively coupled to the one or more perforating guns,
- wherein the downhole assembly is conveyable into a wellbore on a conveyance to axially align the one or more perforating guns with a production zone to create a plurality of perforations in the production zone, and
- wherein the pressure wave resonator is axially alignable with the plurality of perforations and configured to emit pressure waves that propagate radially outward and into the production zone to remove debris from the plurality of perforations.
