Improving the Quality of TEM Data Inversion by Taking into Account the Patterns of Induced Polarization Parameters in the Southern Siberian Platform

The reliability of geoelectric parameters estimation in the south of Siberian platform is an important issue that allows on the one hand investigating polarizability of sedimentary cover as a hydrocarbon indicator, on the other hand it complements significantly to EM data inversion. The inverse problem algorithm is run as a fully automatic multistage process which includes priori data inputs like an initial resistivity model, polarization settings and depth constraints. As a result of that approach the clarification of initial data is performed and a final geoelectric model is derived. The technique that is being discussed in the paper has been tested at one of 3D license block at Nepsky arch and proved to be a valuable exploration tool.
