Control Mechanism of Water Shield on Pressure Dynamics of CO2 Huff-n-Puff and Crude Oil Mobilization Effect in Tight Reservoirs

Tight oil reservoirs are characterized by poor petrophysical properties, ultra-low permeability, and limited pressure-transmission capacity. After hydraulic fracturing, retained fracturing fluid can accumulate near the fracture–matrix interface and form a water shield, which rest...
