Iterative techniques in modeling of multi-phase flow in advanced wells and the near well region

This paper describes a new approach in modeling of multi-phase flow in advanced well completions and in the near well region in the reservoir. The method uses a base solver to calculate pressure distribution, flow rates and phase fractions in all components of the well completion using a simple boundary condition and assuming homogenized flow. The inclusion of three phase flow, multi-lateral wells, more complicated boundary conditions, phase slippage etc. is achieved by iterative techniques using the base solver. Calculated examples are presented for several applications.
