Conclusion

Migrating raw passive seismic data directly produces a cleaner, more crisp image than first correlating the input traces before migration. This new method is faster and requires less overhead, and is very efficient.

Several passive seismic datasets have been collected or acquired from various sources in the last few months. Now that a fully-parallel 3D code has been completed, I will begin processing real data examples that include shallow investigations, ocean bottom cable data, and conventional exploration geometries.

To continue to advance this effort, I am in great need of quality data acquired with as many receivers as possible. It would be very easy to collect such data by simply recording passively from receivers left in the field on a 3D acquisition overnight or during any sort of lengthy down-time. In order to best test the validity of this experiment, simple geology that provides excellent quality conventional data such as the flat limestone of west Texas would be preferred.
