Abstract
Methods and systems are provided for induc ing seismic energy waves in a subterranean formation. More particularly, improved seismic transducers are provided that comprise enhanced baseplates. Baseplates are provided that comprise an intermediate plate and a plurality of contact plates secured to the underside of the intermediate plate. The contact plates provide a surface area for engagement with the ground surface that is more limited than the lower surface area of the intermediate plate. Advantages of such baseplate enhancements include, but are not limited to, a reduction of baseplate harmonics or ringing and enhanced baseplate strength so as to reduce baseplate fatigue or failure, a reduction of baseplate flexure. These advantages ultimately translate to improved seismic surveys, having higher resolution of the formations surveyed and resulting in surveys reaching greater depths.
