Abstract
In article two examples of revision of a geological structure of the fields located on a northern wing of the Zhigulyovsk and Samarkinsky system of shafts on the basis of data of seismic exploration 3D are reviewed. The analysis of seismic studies made it possible to clarify the geological structure of the territory and the associated deposits due to the updating of seismogeological models after drilling new wells and the results of regional work. The revision of building models from anticlinal to tectonically limited ones led to a significant increase in reserves, which is very economically feasible for deposits of the old fund with a developed infrastructure.
