Abstract

The seismic method has been instrumental in finding and delineating oil and gas reservoirs inside the Earth for nearly a century. The method consists of acquiring seismic data, processing those data, and interpreting the processed results to help predict the best drilling locations. I present an overview of these steps, and I emphasize the pitfalls arising from failure to recognize limitations in the steps, individually or in combination. Most or all the material will be familiar to geophysicists, but the conclusions I draw might be surprising.
