Paper presented at the SPE Russian Petroleum Technology Conference, October 22–24, 2019
Paper Number: SPE-197005-MS
... Abstract Currently, a number of software products (PVTSim, WinProp CMG, Aspen HYSYS, etc.) are used in the oil and gas industry, simulating the interfacial mass exchange in natural oils, gas condensate mixtures, etc. Existing software products use the vapor-liquid equilibrium calculation...

..., gas-oil ratio and oil production. The presented approach to gas re-solution control in reservoir simulators is based on data of experimental studies of non-equilibrium phase transitions of hydrocarbons. A flexible tool has been developed for history matching of flow models for the reservoirs...

Paper Number: SPE-176739-MS
... Abstract The paper argues in favor of the need to adjust pVT properties of the hydrocarbon system and apply non-equilibrium models of phase transitions for purposes of upscaling and history-matching flow simulation models (FSMs) to actual production data. Since most of FSMs are based...
