Downhole Pressure Wave Generator And Method For Use Thereof

US Patent:
6012521, Jan 11, 2000
Filed:
Feb 9, 1998
Appl. No.:
9/021025
Inventors:
Gary D. Zunkel - Ames IA
Thomas T. Hansen - Ames IA
Assignee:
Etrema Products, Inc. - Ames IA
International Classification:
E21B 4325
US Classification:
166249
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.
