A new method to determine varying adsorbed density based on Gibbs isotherm of supercritical gas adsorption

Adsorption Science & Technology, 2018
In the calculation of the absolute adsorption of supercritical gas adsorbed on the microporous materials, most existing methods regard the adsorbed density as a constant, which is very unreasonable.

Limited storage and recovery of adsorbed gas in shale reservoirs - Insights from experiments and production modeling

Fuel Communications, 2022
Gas in thermally mature shale reservoirs is considered to exist as adsorbed volume in organic matter and free gas within pores and voids in natural fractures. Gas in-place is derived from summation of aforementioned volumes. Although industry has adopted
