Abstract
Summary
Areas of permafrost rocks distribution occupy about 5 million sq. km of Russia territory. When processing seismic data in areas with permafrost rocks, its influence should be taken into account. Ignoring the complicated structure of permafrost zone can lead to significant errors in prospective horizons structure. Static corrections calculation by conventional methods (by smoothing the variations of the travel time) sometimes can result in artificial synclines arise on the section. The authors propose an approach to the elastic properties of the upper part of the section recovering from Shallow TEM data.
