The effect of vacancy defects on the adsorption of methane on calcite 104 surface
(
Elsevier Editora Ltda
, 2021 , Article)
Density functional theory calculations are used to study the effect of vacancy defects (ionic Ca and charge neutral CO3) on the adsorption properties of CH4 molecule on different calcite surfaces. Both types of vacancy ...

For many years, the oil and gas industry has strived to develop environmentally friendly organophosphorus-based scale inhibitors. The natural polymer chitosan has recently gained significant importance for various upstream ...
Phosphonated Lower-Molecular-Weight Polyethyleneimines as Oilfield Scale Inhibitors: An Experimental and Theoretical Study
(
American Chemical Society
, 2022 , Article)
For many years, amino methylenephosphonate (-CH2-N-PO3H2)-based scale inhibitors (SIs) have been deployed for preventing various scales in the oil and gas industry, particularly for squeeze treatment applications. However, ...
