Key words: exploration of new deposits, reserves increacing, production test (perforation), initial oil rate.

The paper illustrates the comprehensive approach towards the discovery of the “lost” deposits at presently operated fields which allows revealing the significant potential to increase the oil reserves. The practical efficiency of the considered approach (“Search”) and the commissioning of the “lost” deposits into the process of active field development allows building-up the reserves and oil production at minimum capital investments. The results of this works are the annual basis for individual program of further well studies. The realization of the program to evaluate the resource base in 2010 - 2011 has enabled to discover 17 new pools at 15 deposits. The majority of new pools has been commissioned into active operation and has resulted to the increased total oil production.
