The development of refracted waves method

At present refracted waves processing is mainly restricted to arrival times analysis. Dynamic parameters of<br>refracted waves are only used for the wave identification and separation. In particular, the relationship<br>between amplitude of refracted waves and refraction coefficient is not investigated while it is a standard<br>procedure in processing of reflections. The most correct processing using kinematic and dynamic wave<br>properties is based on the migration procedure, which results in the images of refracted interfaces with<br>complex geometry. The original method of refracted wave migration based on Kirchoff algorithm is<br>proposed here. As a result, dynamic cross-section of refracted interfaces similar to standard CMP crosssection<br>is derived. The joint processing of refracted and reflected data allow to obtain more reliable results<br>that should improve the accuracy of structure constructions and the prediction of geological models.
