Abstract
The present disclosure relates to increasing the output power of a clamped seismic or acoustic source disposed in a wellbore without damaging the borehole/casing/cement. One or more sources are provided and carried on a conveyance mechanism. The conveyance mechanism may be a wireline, a coiled tubing, or a drill pipe. The one or more sources are run into and/or out of the wellbore and temporarily disposed at various locations within the wellbore. The one or more sources are temporarily clamped to the wellbore at the various locations using distributed clamping, and a source signal is generated by the distributed clamped source. The distributed clamping device may have multiple clamping mechanisms along an increased length of the source or a continuous clamping mechanism along an increased length of the source.
