<p>A pressure wave generator (36) for use down in a bore hole (22) having fluid (32) therein adjacent a fluid-containing formation (31). The generator (36) includes an elastomeric member (46) sized for disposition in the bore hole (22). A periodic compressive force is exerted on the elastomeric member (46) in a first direction so as to cause the elastomeric member (46) to expand in a second direction and thus produce pressure waves in the fluid (32) to increase the effective permeability of the fluid-containing formation (31). A method for using the generator (36) is also provided.</p>
