Opening of natural fracture and its effect on leakoff behavior in fractured gas reservoirs

Fluid leakoff is one of the most important issues frequently encountered in hydraulic fracturing, especially in naturally fractured gas reservoirs. Opening of natural fractures will bring about excessive fluid loss and restrain the propagation of major hydraulic fractures. A mathematical model of natural fracture dominant leakoff in fractured gas reservoirs has been developed in this paper. Besides, the opening mechanism of natural fractures has...
