Optimization of development of deposits T-1 horizon at Timofeevskoye and Kulychyhynskoye OGCF using the cycling process by partial replacement of gas by nitrogen recirculation can release the commercial gas from recycling without reduction of rate of heavy hydrocarbons (condensate, propane, butane) production that will significantly increase the efficiency of two deposits. Partial replacement of gas by nitrogen recirculation during the 2014-2021 will provide the commercial gas production at 124.1 million cub. m/yr or tota1992.8 million cub. m. On condition of realization of gas on commercial prices (S2S USD/1000 cub. m) the economic effect can reach 238 million USD. The prime cost of gas will be 50 USD/1000 cub. m. According to preliminary feasibility study, the investment at construction of nitrogen cryogenic unit with capacity of 400000 cub. m/day of nitrogen will be 22.3 million USD and will pay off in the second year of project. Without reducing the production of liquid hydrocarbons (gas condensate + propane-butane) the state will be provided by hydrocarbon gas production at 124.1 million cub. m/year.
