Equations predict gas well dispersed gas-liquid pressure, temperature

05/20/2002
The application of microscopic momentum balance, energy balance, Peng-Robinson's equation of state, and heat transfer equations can predict the pressure and temperature profiles of a pseudohomogeneous gas-liquid mixture in a gas production well.One can consider a dispersed gas-liquid mixture flowing at high velocity in a gas well to be pseudohomogeneous.Peng-Robinson's equation of state calculates the local density and partial derivatives of the high-pressure gas in the gas phase. Heat balance and heat transfer equations determine the heat loss of the flowing gas-liquid mixture through multiple layers of steel walls and casing fluid to the surrounding formation. Momentum and energ...
