Abstract:
A pressure wave generator for use down a bore hole having fluid therein adjacent a hydrocarbon-containing formation. The generator includes an elastomeric member sized for disposition in the bore hole. A periodic compressive force is exerted on the elastomeric member in a first direction so as to cause the elastomeric member to expand in a second direction and thus produce pressure waves in the fluid to increase the effective permeability of the hydrocarbon-containing formation. A method for using the generator is provided.
