• The following parameters of natural gas, gas condensates, and oils are determined: Saturated vapor pressure; Mass fraction of water; Mass fractions of chlorides; Mass fractions of mechanical impurities; Densities of gas condensates and oils; Mass fractions of mercaptans; Fractional composition of oil; Kinematic viscosity; Component composition of gas; Mass fractions of asphaltenes, paraffins, and silica gel resins; Mass fractions of aromatic hydrocarbons; Hydrocarbons in oils and gas condensates by gas-liquid chromatography method; Indicators such as calorific value, relative density, and Wobbe index; Additionally, Physical-chemical analyses of extracted products, and; Hydro-chemical monitoring of the watering of oil and gas wells.
