Kerogen, as a highly porous material, exhibits significant adsorption capacity for various fluids, including hydrocarbons, water, and gases. The adsorption behavior of kerogen depends on factors such as the composition of the fluid, the properties of kerogen itself, and the prevailing pressure and temperature conditions formations. The type and composition of hydrocarbons, as well as the maturity and type of kerogen, influence the adsorption behavior. Understanding the adsorption properties of kerogen is crucial for assessing the storage potential and estimating the recoverable hydrocarbon resources in shale reservoirs.
