Artificial maturation of a high volatile bituminous coal from Asturias (NW Spain) in a confined pyrolysis system

Vitrinite reflectance, and Tmax were calculated from the model by describing the kerogen transformation under the action of typical temperature of burial. From the spatial distribution of the vitrinite reflectance, and after the depth, the importance of the hydrocarbon production was estimated by the simulation and artificial maturation and compared with the gas quantities adsorbed by coal. Two mechanistic pathways relating to CH4 production and CH4 adsorption from coal were built to estimate the real exploitable gas proportion as function of depth and the geographical location of the coal seams in the basin.
