Step One:

The well is sealed to confine the treatment area and gaseous CO2 is injected, producing a mildly acidic, highly abrasive carbonic acid, penetrating far into the surrounding formation.

Step Two:

Liquefied CO2 (0°F) is injected into the well and surrounding formation where it expands rapidly (570:1), producing the necessary energy to detach, dislodge and remove mineral encrustation and biofouling.

Step Three:

The CO2 is released and the well mechanically developed using pumping & surging to remove the newly dislodged plugging material from the well and formation.

Step Four:

The well pump is reinstalled and the well returned to service, providing an increased supply with no hazardous waste stream to dispose of.
