Marine Seismic Vibrators and Methods of Use

摘要

Embodiments relate to marine seismic vibrators for use in seismic surveying and associated methods of use. An embodiment provides a marine seismic vibrator comprising: a shell having a spring constant selected to provide a first resonance frequency within an operational frequency range of about 1 Hz and about 300 Hz; a driver disposed within the shell and having a first end and a second end; and a spring element coupled to the shell between the first end and the second end of the driver, wherein the spring element has a second mode of oscillation that provides a second resonance frequency within the operational frequency range.
