Initial evaluation has been undertaken for improving tomographic images in vertical seismic profiling (VSP) by utilization, in addition to direct wave, the reflected wave as well. This evaluation has been performed basing on model computations. The input data in tomographic inversion have been traveltimes generated using ray tracing with curved rays for selected seismogeological medium models. It was proved that when we use traveltimes of wave reflected from the reflector in the bottom of transmission medium we can considerably improve the range of medium coverage with seismic rays and create a possibility to define much more precisely the location of velocity heterogeneities during tomographic inversion.
