Adsorption of polyphosphinocarboxylic acid (PPCA) scale inhibitor on carbon nanotubes (CNTs): A prospective method for enhanced oilfield scale prevention
Application of CNTs in squeeze treatment to increase scale inhibitor adsorption. Faster and higher adsorption of scale inhibitor on CNTs compared with on formation rock. Longer squeeze treatment lifetime and shorter shut-in by using CNTs. Strong adsorption on CNTs results in longer PPCA retention in the near wellbore area.
