Improved Seismic Data Acquisition, Processing, and Interpretation Techniques in Sacramento River Delta--Case History

J. A. Austin, L. F. Schuetter, S. J. Kiouses

The Sacramento River delta is an area that holds great challenges to the geophysicist in the matter of prospect delineation by the reflection seismic method. This area is a vast network of rivers, sloughs, and levees, with intense agricultural development and peat soils.

These peat soils are responsible in part for statics problems, velocity gradients, ground roll, and attenuation. A highly coordinated effort brought forth many solutions to these data quality problems in the realms of acquisition, processing, and interpretation techniques.

Due to these improvements, an anticlinal feature was mapped at the Winters sand layer, which was a northern structural extension of the Roberts-McDonald Island trend. An exploratory well was subsequently drilled and encountered the Winters sand in a structurally high position remarkably close to that predicted by the geophysical mapping.
