|Abstract:||The gas-liquid flow in a stimulated shale formation is described with a new formulation of the Multi-Phase Mixture Model. The effects of the phase changing on the fluid flow are considered in both mass balance and momentum conservation equations. Without loosing consistency, an advanced phase-mixture model is applied, stable and consistence numerical methods are implemented for a full space-time discretized system. Compared with those obtained from classical approaches, the saturation results show how the momentum exchanged through phase changing can affect the dynamic flow in fractured shale zone. Furthermore, the developed model is suitable to deal with non-Darcy flow conditions in the neighbouring zone around the wellbore where shale permeability is increased by fracturing.|
