Phase characteristics modeling of reservoir gas-condensate mixture of Tegermen group of fields

Abstract

Taking into account the forthcoming concept, it is proposed to develop Tegermen group of fields with construction of onshore systems for collection, treatment and transportation of natural gas in order to supply the extracted products to the gas treatment point (Samantepe gas treatment unit-2) in a single-phase state. Natural hydrocarbon systems consist of a large number of components, and these are not only hydrocarbons of the paraffin series, but also hydrocarbons belonging to other groups. The phase state of a hydrocarbon mixture depends on its composition, as well as on the properties of individual components. Construction in a wide range of temperature and pressure values of phase diagrams of reservoir fluids with low condensate factor allows to determine with high accuracy the parameters of the beginning of condensate precipitation (dew point) in the system of gas gathering and transportation to supply the produced products of Tegermen group of fields.
