... experimental result complex reservoir methane radial direction experiment diffusion coefficient permeability effective stress exact solution test gas Introduction Shale reservoir becomes more and more important in the world ( IEA 2017 ), especially the large-scale production of shale gas...

... along the radial direction for a given production time and shut-in duration. To make it more general for other wells, an empirical correlation is provided through regression on the calculated type curves. The difference between this semi-analytical solution with other previous efforts will be discussed...

.../beddings or a horizontal zone filled with different minerals. For the tight sand plug, wave velocities measured along the axial direction are in good agreement with those from the radial direction. However, the similar phenomenon was not observed for the shale plug. We analyzed the discrepancy using...

... focuses on the effect of various concentrations of bidispersed suspensions in a laminar vertical pipe flow. The average particle settling velocities and the fluid velocities are determined at two different flow rates. It is also important to consider the particle distribution along the radial direction...
