Seismic Reflection Processing For Characterization Of A Hazardous Waste Site

Seismic reflection data have been acquired by the Kansas Geological Survey near the Oak Ridge<br>K-25 Plant on the Oak Ridge Reservation, Tennessee, to assist in the selection of ground water<br>monitoring well locations. The data were recorded in uncorrelated format to allow flexibility in<br>enhancement of stacked images.<br>During the summer of 1996, five of the thirteen seismic reflection lines acquired were<br>processed. An unconventional correlation procedure, “Vibroseis Whitening” (VSW) (Coruh and<br>Costain, 1983) has been applied to produce improved seismic sections. Refraction statics<br>corrections, which remove the detrimental effect of an irregular weathered layer, have also been<br>utilized to improve the seismic sections. The seismic data were stacked using the velocities<br>obtained from a standard semblance velocity analysis tool. Locations and orientations of faults<br>or fault zones can be interpreted from these stacked sections, and they are in agreement with the<br>interpretations of the surface mapping in the area.<br>This paper concludes that VSW and refraction statics can be important to near-surface<br>swept source seismic data processing.
