Effect of gas reserves dissolved in formation water on the current distribution of the components volumes in oil wells production

Authors: N.A. Gultyaeva, V.V. Krikunov (Tumen Branch of SurgutNIPIneft, RF, Tyumen)

Key words: oil, gas factor, residual gas-oil ratio, dissolved gas, fluid phase equilibria.

The general principles of mass transfer in the oil-gas-water system are presented under temperature and pressure conditions of formation and rise to the surface. The influence of dissolved gas on the gaseous component in the value of production wells are shown for deposits being developed with the waterflooding. A model predicting the phase behavior of water-oil mixtures, based on the equations of material balance of component-wise is proposed.
