Well Rehabilitation
Definition
Well rehabilitation encompasses a range of treatments and repairs used to recover or improve a well’s performance. Common rehabilitation techniques include mechanical cleaning to remove mineral encrustation or bacterial growth from the casing and screen, chemical treatment with acid or chlorine to dissolve mineral deposits or disinfect bacterial biofilm, redevelopment to improve the flow of water from the formation into the well, pump replacement or optimization, and in some cases, well deepening. Rehabilitation is most commonly indicated when a well’s GPM has declined significantly from its original performance, when water quality has changed, or when the well is recovering slowly from heavy use.

How Trident Drilling Company Uses It
Trident Drilling provides well rehabilitation services including mechanical cleaning, redevelopment, and well deepening. Each rehabilitation begins with a site visit and assessment to identify the root cause of performance decline — whether that is mineral encrustation, bacterial fouling, a dropped water table, pump degradation, or structural casing issues. Trident provides a rehabilitation recommendation and cost estimate before any work begins.
