The stages of prospecting and exploration of oil deposits at the territory of eastern regions of the Republic of Tatarstan and the efficiency of geological survey works are considered. At the present stage to solve the problem of further petroleum reserves increment low-cost "light" geophysical and geochemical methods and integrated geological and geophysical analysis data are involved. As a result, the efficiency of exploration drilling is significantly improved, a significant increase of reserves of industrial category С₁, the estimated category С₂ and resources С₃ is obtained.
