Presented are the results of oil recovery technologies, implemented at AB11-2 "Riabchic" formation of Samotlor field, with comparison of their efficiencies. It is shown, that the best effect is reached by hydraulical fracturing of formation, which is recommended as a basic measure for oil production enhancement. It is noted, that development scheme for AB11-2 "Riabchic" formation is comprised of a number of units with different configurations under pattern water flooding, with wells, drilled directly into formation, and "returned" wells, recompleted from underlying formations after fulfilling their designed targets, and wide implementation of hydraulic fracturing.
