... of their geological characteristics. Additionally, the massive number of depleted wells in the US shales makes it a viable option for carbon storage. Shales are known for their high organic content, which enhances CO2 adsorption into the geological formation, which in turn enhances the storage capacity and formation...

... Abstract Asphaltene adsorption on reservoir rocks, particularly those near the wellbore, has been debated for decades, but a long-term solution is still difficult. This is partially because research into the chemistry of asphaltene is still ongoing, as is the creation of solutions that depend...

... Abstract Experimental methods are commonly used to determine the ability of a rock to adsorb gas by means of isothermal adsorption experiments. Adsorption isotherms quantitatively describe the relationship between the amount of gas adsorbed onto a rock surface and associated equilibrium...

...-up water recipes were used with salinity ranging from 400 to 167,000 ppm. Further, static and dynamic adsorption studies were conducted at ambient temperature (25 °C) to investigate polymer performance and polymer-rock interactions. The water recipes with salinity less than 10,000 ppm showed better...
