The analysis of resolution of electrical survey with the use of modified source of the electromagnetic field

Nowadays the fundamental problem of reconstructing the solid field distribution into the solid<br>distribution of medium conductivity has been solved by the applied electrical survey based on<br>the transient electromagnetic fields. It holds the great promise for the use of the dense spacetime<br>observations systems in electrical survey for the solution of such problems as oil prospecting,<br>reservoir monitoring, comprehensive study of ore deposits, kimberlite fields and others. Inductive<br>and galvanic field sources can be used for area observation systems. The evaluation of<br>their efficiency is of great importance for 3D electrical survey technology. In this paper the<br>comparative efficiency of the five field source is considered using the solution of oilprospecting<br>task under the conditions of the Siberian platform as an example.
