The in?uence of adsorption layer thickness and pore geometry on gas production from tight compressible shales

In tight shales, gas is stored in both free and adsorbed form. A one-dimensional model derived for shale production by pressure depletion where the layer thickness of similar magnitude as pore radius can affect ?ow performance. The a function pressure. Different geometries are assumed varying continuously between spherical pores to more fracture shaped pores. compressible its porosity reduce with depletion. effective (pore minus adsorption thickness) controls intrinsic apparent permeability. impact layer, compressibility geometry investigated. given ?lls when they concentrates volumetric boundaries giving lower permeability radius. Increasing increases fraction initial place. high volume reduces delays production. Pressure causes be reduced. change low at greater pressure, while changes linearly higher compressibility. saturation slip cases, but if matrix compression dominates there net reduced Recovery was linear square root time all cases.
