Gas condensate tests of wells in the Achimovskaya strata of the Urengoyskoe feld

The article describes tests and the results of the integrated exploration of formation hydrocarbon system gas-condensate characteristics of wells of the Achimov deposits of the Urengoyskoe feld, situated in the area 2A of the experimental program, concerning with the depletion ofthe reservoir energy, taking into account their unique geological and physical parameters.
Materials and methods
Separator gas, gas condensate, formation gas, field complex gas condensate studies, compositional analysis, physical and chemical properties of the formation gas.
Results
Research results make it possible to predict the condensate yield C5+В in the recovered reservoir gas. It was also found, that wells should be operated under the differential pressure not more than 30% from formation pressure in order to prevent considerable the specific yield of the condensate and to reach the planning production volume. The application of modern methods of well survey exploration without gas popping prevent from hydrocarbons wastage and lower the environmental footprint.
Сonclusions
The results of the integrated exploration of formation hydrocarbon systemgas-condensate characteristics are considered to be the basic ones for substantiating and drawing up operating practices of well operation, updating the condensate recovery factor and hydrocarbons planning production of the Achimov deposits (Urengoyskoe field).
