... window, require high mud weights to prevent borehole collapse. Therefore, wells are drilled with inherent risks of stuck-pipe, fluid losses, and possible set contingency casing string - all of which can be very expensive in terms of equipment, and lost time. Drilling through shale is inevitable. Shale...

..., and mitigates the solvent injection ( Berawala & Andersen, 2020 ). Therefore, adsorption is an essential mechanism when modeling gas production or gas injection in shales to accurately predict the gas reserves, recovery rates, and reservoir storage capacity of the injected gas. While many studies...
