Abstract: Currently, the field in article is a brown oil field, characterized by high costs of extracting remaining oil reserves. Dual production is actively used at the deposit, with all productive layers being developed by mechanized methods. To increase the efficiency of oil recovery and reduce operating costs, it was proposed to optimize the equipment layout for dual production of two objects and use a mechanical pressure transducer in combination with a sucker rod pump. In this study the candidate well was selected, the technical data of the pressure multiplier was calculated and equipment was selected using existing methods. The device does not require the supply of energy from the surface, which allows reducing the cost of operating development facilities.

Abstract: The problem of gas and gas condensate wells flooding was considered. The existing methods of control of the complication were analyzed. The conclu- sion about highest effectivity of artificial lift systems was made. The basic con- figuration of the gas and gas condensate wells equipment for artificial water recovery was discussed. A concept of submersible pump was designed that is able to operate with high gas concentration and large amount of suspended particles
