The main provisions of the tomographic approach in pulsed electrical exploration are considered. The proposed approach is based on a multi-angle observation system where the object is irradiated from differentsides at a high density of the observation network. At the same time, two statements of inverse problems are considered, they are closely related to the tomographic approach. The first problem is searching andvisualization of medium inhomogeneities. The second problem is determination of electrical characteristicsof the identified inhomogeneities. The article considers examples of solving these problems. generating rocks. It is concluded that the lithification asynchrony of the fluid seal clay deposits predetermined the time diversity of the HC accumulation generation in the Malyshevka Formation in geological past.
Keywords: Induction tomography, reference model of medium, inverse problems in methods, eltranslog, linear approximation.
