Abstract
The present invention provides methods and apparatus for enhancing the production of liquid hydrocarbons from a subterranean formation penetrated by a well bore. The methods basically comprise placing one or more electric powered sonic energy transducers actuated by magnetostrictive actuators which preferably have drive rods formed of terfenol alloy in the well bore, and causing sonic energy to be emitted from the transducers in the form of pressure waves through the liquid hydrocarbons in the well bore and/or in the formation thereby causing the liquid hydrocarbons to flow into the well bore and to the surface more freely.
