Gas condensate stable autofilling in Ufa
When, while drilling on gas and condensate fields, the temperature drops to a level below the dew point of the produced hydrocarbons, condensation of raw unstable condensate (raw gas condensate) occurs. In addition to C5 hydrocarbons, it contains dissolved gases of the methane-butane fraction (from CH4 to C4H10), which facilitate the extraction of petroleum products from the field. Unstable gas condensate is subjected to additional preparation. The product is purified from impurities and light hydrocarbons (methane, propane and butane), and is also subjected to gas separation (degassing). As a result, it becomes stable - it contains no more than 2-3% propane-butane, gasoline-kerosene and gas oil fractions. Stable gas condensate is divided into 2 types: Field. The product is obtained directly at the extraction site. Factory. Produced at gas processing plants (GPPs).
