One of the considerable problems often arising in the course of backstripping (paleogeography reconstruction) within the certain area is the fact that the prediction carried out is mainly zonal or local with no focus on regional forecast. Mapping facies zones and paleochannels is often carried locally in the area of subsoil user interest, predominantly withing the boundaries of 3D survey; and there is a problem of scaling. Analysis of regional trends allow determining factors of depositional settings, dynamics of sediment transportation and accumulation environment, which, in turn, makes a basis for mapping elements of paleodrainage system within the territory in question. This prediction format allows identifying key common features of exploration target distribution over the area, mapping stratigraphic and combination traps as they are of primary interest for further geological exploration activities.
