... to the extra pressure drop in near well region. The non-Darcy effect in gas reservoirs have been realized and studied by researchers for many years. Research results show that gas flow in the near well region cannot be adequately represented by Darcy law due to high flow velocities. In conventional well...

... Abstract The developments of gas fields and laboratory experiments present that there are great differences in the well performance and well productivity between different wells with the same reservoir petrophysics. The characters and distributions of the tight gas reservoirs are not yet well...
