Accurate knowledge of the physical properties of natural gas is critically important for effective design, operation and optimization of technological processes in the oil and gas industry. The relevance of this work is due to the need to obtain reliable data on the physical properties of the Urengoyskoye field gas, which will improve the accuracy of modeling and forecasting the operation of the gas transportation infrastructure and optimize gas processing processes. The purpose of the article is to determine the basic physical properties of natural gas from the Urengoyskoye field based on initial data on density under standard conditions, molar fraction of nitrogen and molar fraction of carbon dioxide, using the methodology described in GOST 30319.2–2015. The research is based on a theoretical approach based on the application of correlation dependencies and equations of state defined in the specified GOST. The initial data on the composition of the gas were used as input parameters for calculating its physical properties, such as viscosity, heat capacity, compressibility coefficient, etc., in accordance with the algorithm provided for in GOST 30319.2—2015. As a result of calculations, quantitative values of the basic physical properties of the natural gas of the Urengoy field in a wide range of temperatures and pressures were obtained. The obtained results are presented in the form of tables and graphs demonstrating the dependence of physical properties on temperature and pressure. The conclusions of the study confirm the effectiveness of the application of GOST 30319.2—2015 for calculating the physical properties of natural gas. The obtained data on the physical properties of the gas from the Urengoyskoye field can be used to accurately simulate the operation of gas pipelines, optimize processing processes and increase the efficiency of the entire gas production. The work demonstrates the possibility of using standard techniques to obtain important engineering data.
