Abstract:
By exploring huge gas-condensate reservoirs, three-phase transient flow modeling demonstrates its crucial role in designing dynamic kill, relief well parameters and kill procedure of such wells. Controlling gas-condensate well needs robust transient three phase models capable of capturing discontinuities in density, geometry and velocity of phases. In this paper, two phase Advection-Upstream-Splitting-Method hybrid scheme is extended to three-phase model capable of modeling blowout and dynamic kill in gas-condensate-water wells. Density and viscosity changes are calculated using Peng-Robinson equation of state and in according, flow model parameters are corrected.The capability of this model to handle highly changing flow during blowout and dynamic kill is demonstrated with examples of sensivity analysis on relief well kill rate and well intersection depth.Demonstrated simple transient three-phase model is useful in designing similar procedures for controlling gas-condensate-water wells
