he gas-liquid jet apparatus (GZhSA) for increasing the volume of gas production at multilayer oil and gas condensate fields was developed by specialists of RN-Purneftegaz (a production asset of Rosneft). The use of GZhSA makes it possible to simultaneously operate high-pressure and low-pressure wells. Pilot tests at the RN-Purneftegaz Gubkinskoye field have demonstrated the economic effect of using GZhSA in the amount of 21 million rubles at a total capital cost of not more than 500 thousand rubles.
The introduction of advanced approaches and new technologies is one of the key areas of the Rosneft-2022 strategy. The company pays special attention to innovative development, identifying technological leadership as a key factor in competitiveness in the oil market.
Gas-liquid apparatuses have a wide application potential in fields with gas deposits. At a late stage of development, when reserves are depleted and reservoir pressure decreases, some of the low-pressure wells are forced to be inactive, or are not operating in optimal conditions. The pressure drop occurring in the apparatus makes it possible to make profitable uninterrupted operation of low-pressure and high-water-cut wells.
