Mathematical Modeling of Coal Bed Methane Generation
Abstract: Coal-Bed Methane reservoirs have a number of unique features compared to porous or fractured gas reservoirs. Here, the paper presents 2-D mathematical model of coal bed methane generation/storage based on the theories of surface physical chemistry such as Langmuir adsorption isotherm. In this paper, Gibbs isotherm, Langmuir adsorption isotherm, porosity and surface excess are used to derive a formula which is helpful in simulating the generation of Methane adsorbed by coal beds in a real time scenario by assuming gas as ideal gas. Here, results are verified by plotting graphs and then comparing them to field data.
Keywords: Langmuir adsorption isotherm, CBM Coal Bed Methane, Gibbs isotherm, time relation
