WELL-KLEAN© TOOLS
Well rehabilitation tools.
The mechanical tools authorized Well-Klean© contractors use alongside the chemistry — brushes, swabs, plungers and isolation tools that liberate biofilm and scale so the treatment can reach the gravel pack.

WHERE THE TOOLS FIT
Tools liberate the deposit. Chemistry removes it.
In the Well-Klean© rehabilitation process, mechanical tools do their work in Step 05: brushes, plungers and tremie pipe break biofilm and scale loose from the casing and screen, then one to three bioremediation cycles with controlled soak times, plunging and agitation carry it out of the well. Isolation tools confine the treatment to the section of screen being worked, so the chemistry and soak time are concentrated where the problem is instead of diluted across the whole column.
Every tool on this page is used alongside the chemistry, not instead of it. HCT prescribes the tooling, soak times and sequence for each well from its analytical data and video survey, and the work is carried out by an authorized Well-Klean© contractor to HCT best practices.
WHY TOOLS ALONE DO NOT HOLD
Mechanical is supplemental, never the standalone method.
Sonar jetting, air blasting, high-pressure jetting and brushing can dislodge loose debris. They cannot chemically degrade the polysaccharide matrix that binds biofilm and mineral deposits to well surfaces, so deep deposits in the gravel pack stay put and residual biofilm re-seeds the well. That is why each mechanical-only cycle yields less recovery over a shorter period, and why the Well-Klean© sequence breaks the biofilm first with WaterSOLV™ BC, dissolves the scale it was protecting with Well-Klean© Descaler, and only then relies on tooling and development to flush the well clean.
