Transport of CO2 in Stimuli-Responsive Fracking Fluid, StimuFrac

Published by Pacific Northwest National Laboratory | Department of Energy | Metadata Last Checked: January 27, 2026 | Last Modified: 2018-06-12T21:58:31Z
CO2 breakthrough experiments in a column packed with sand and filled with StimuFrac fluid or water to learn about transport of the stimuli (CO2) on environments where either water or the stimuli-responsive polymer aqueous solution (StimuFrac) is present. Results suggest co-injection of StimuFrac and CO2 as the potentially best alternative to deploy this novel fracking fluid.
