SeismicCity services

We offer both ray based and wave based prestack depth migration (PSDM) algorithms. The ray based PSDM is a wavefront reconstruction Kirchhoff summation algorithm. The wave based PSDM is a two-way Reverse Time Migration algorithm.

The quality of the final depth migrated volume is only as good as the velocity / anisotropic model constructed during the model building phase. We devote the majority of the depth imaging process to building an accurate anisotropic model. Our workflow is based on repeated iterations of full volume prestack depth migration where at each iteration the model is updated using the results from the prior depth migrated volume. Every model building iteration is performed using full volume prestack depth migrated data.

An integral part of depth imaging is the use of simulation to assist in understanding field acquired and depth imaged seismic data. We are offering full wave equation simulation as part of our services. Simulation is done to help in investigations of: Seismic illumination, Imaging artifacts, Acquisition design.
