Lateral topographical and velocity changes in the near-surface lead to time anomalies during seismic land surveying. Having a correct and dependable model of the near-surface geology is crucial for good seismic imaging. SeisUP® includes an advanced refraction statics correction package for creating a shallow earth model and applying the necessary time shifts to seismic data traces.
SeisUP® also has a comprehensive set of modules for calculating and applying residual statics, in a surface consistent manner or by CMP, depending upon the goals of the processor. The result of correcting for these surface anomalies is an increase in trace-to-trace coherency within each CMP as well as improvements in the lateral continuity of stratigraphic units, which results in better overall imaging of the subsurface structures.
