Application of temperature-dependent adsorption models in material balance calculations for unconventional gas reservoirs

Heliyon, 2019
Langmuir isotherm is the most common adsorption model used in the prediction of gas adsorption in most shale and coal bed methane reservoirs. However, due to the underlying assumption of single temperature, it fails to model gas adsorption where ...
