Data for: Numerical Simulation of Multi-seam Coalbed Methane Production Using a Gray Lattice Boltzmann Method

Description

The data shows the contribution rate of gas production under different permeability contrast. Note that the contribution rate of high permeability seam is always higher than that of low permeability seam. When permeability contrast K1/K2 < 10, the contribution rate varies greatly with the variety of permeability contrast. When permeability contrast K1/K2 > 50, with the increasing permeability contrast, the contribution rate of low permeability seam tends to be 0 and the commingled production is mainly contributed by the high permeability seam.
