Performance Evaluation Of A High-freqency Borehole Seismic Source
Abstract
A simple, arc-discharge seismic source for application to the borehole environment is described. Test results from a performance evaluation in sedimentary, metamorphic, and igneous sections are presented. These results demonstrate repeatability of seismic signatures in a variety of geologic settings for a waveform with a dominant period of about 1.5 kHz and a half-power bandwidth in excess of 1 kHz. The ability of the sparker to operate in a borehole under hydrostatic heads in excess of 400 m, at lateral ranges in excess of 100 m, and at angular ranges in the vertical plane to 70 degrees is demonstrated.
