Smoke and Mirrors: demonstrating interferometry on synthetic converted wave data

David C. Henley

ABSTRACT

Over the last several years, we have developed and demonstrated techniques for removing the near-surface effects (statics) from seismic traces, using interferometric methods, and have shown how to generalize constraints like surface-consistency and stationarity. We have shown significant results using field data from the Canadian arctic. More recently, we have adapted these methods to converted wave data, where the receiver corrections are difficult to determine using conventional methods. This work illustrates the testing of interferometric methods on several related synthetic models, each designed to isolate and study a particular issue raised by converted wave interferometry. We introduce various procedures for improving our results, and show them in practice on the model data. Our insight for dealing with real data has been significantly increased by the study.
