Numerical simulation of gas reservoir incorporating the effects of slippage and adsorption

In this work, we incorporated the effects of slippage and adsorption into transient productivity index to determine pressure in horizontal wells simulation natural gas reservoirs. We modeled by introducing an apparent permeability, a function Knudsen number, while is using Langmuir isotherm. As for index, included one classic Peaceman reservoir-coupling models, which integral exponential polynomial approximation with wide range applications. studied different production scenarios, leads mitigation numerical storage. Besides, showed that adsorption, slippage, well influence reservoirs low permeability.
