High Resolution Seismic Reflection Test At The Doe Hanford Site

A recent test was conducted to ascertain the benefits of swept source technology for use at the DOE Hanford Site.<br>Previous high resolution seismic surveys suf?ered from coherent noise interference, poor signal transmission and lack of<br>borehole velocity control. P-wave data were collected with the T-2500 Minivib produced by IVI, Inc. and Oyo<br>Geospace’s DAS- 1 acquisition system. Results showed a significant increase in signal-to-noise ratio, increased<br>resolving power and better depth penetration of the signal. It is concluded that swept source technology as part of a total<br>systems approach, significantly expands the capabilities of the shallow high resolution seismic reflection method for use<br>at the DOE Hanford Site.
