Abstract
Using a rigorous thermodynamic approach, a method is developed to numerically model the liquid–gas equilibrium in a multicomponent hydrocarbon mixture that models oil containing dissolved gas. The calculated results are compared with observed data. A mathematical model is elaborated to calculate oil hydrodynamics in a well in which a pump is installed. A method is proposed to determine the pressure at the well bottom. The effect of oil degassing in the reservoir and in the well on the well productivity is studied.
