The present invention relates to a Carbon Capture Utilization and Storage (CCUS) opportunity through well rehabilitation. Aqua Freed® and Aqua Gard® are well-known well rehabilitation and preventive well maintenance technologies that utilize (inject into the subsurface in a methodical way) liquid CO2 for the purpose. The object of this invention was to quantify the storage capacity of Aqua Freed® and Aqua Gard® and establish their CCUS credentials.

The invention relates to a method of well rehabilitation using CO2. The improvement comprises providing a more effective distribution of effective energy throughout the entire well structure including all parts of the producing interval of the well and surrounding formation and distributing energy throughout the entire well structure. The improved method is obtained by controlling CO2 phase changes during CO2 injection to cause surging agitation within the well bore and surrounding formation and allowing CO2, mechanical energy and optionally chemical energy to reach substantially all area of the well.
A method of preventive well maintenance with pumping equipment in the well for well rehabilitation using CO2 with varying lengths of producing intervals utilizing varying methods to deliver cleaning energy and varying porosity of aquifers to determine varying quantities of energy over the entire well structure.
A water-well maintenance system for use in screened wells, open-hole wells, vertical wells, horizontal wells, collector wells, injection wells, and environmental recovery wells, namely, a permanently-installed device on a water-well that allows for the injection of carbon dioxide into the well to keep geological surfaces clean, maintain pore volume in a well and an aquifer, and improve raw water quality without having to stop or remove the pumping equipment from the well
