The main problem of pipeline transport of associated petroleum gas (APG) and natural gas – the need for transfer of a multicomponent hydrocarbon mixture. The purpose of this paper is the disclosure of technical, methodological, and economic aspects of a comprehensive approach to training, transportation and processing of gas through the use of supercritical states of multicomponent hydrocarbon mixtures for deposits of oil company OAO "Rosneft" in the Western and Eastern Siberia. The development of this technological approach allows oil and gas organizations to more effectively utilize resources and achieve routine associated gas utilization degree of the problem which, to date, is associated with a weak refinement and low cost-effectiveness of technologies proposed for utilization of associated gas. Of particular importance in this context takes the introduction of innovative technologies capable of solving many problems faced by the subsoil user during transportation of hydrocarbon gases.
