Methodology for Studying the Transit Zones (Using the Example of the Perm Krai)

Based on experience obtained in the Perm Krai and other regions of the Kama River basin, the paper examines the specifics of seismic exploration in transition zones, which are the shallow waters inaccessible to study using just river or land-based survey alone. Successful seismic exploration in these zones relies on the use of a number of new technologies, including the explosive source placed in boreholes below the silt zone of the river bottom, and a system of compact equipment, and drilling rigs that enables exploration in ice-covered waters.
