WELL REHABILITATION
Well maintenance of older wells is an important part of Rodgers & Company’s business. Drilling a new well represents a large investment in time and money, so the cost benefit of rehabilitating an existing well can be significant. The time required to obtain a permit to drill a new well alone is enough justification to devote considerable resources to rehabilitating an old well.

Over time, wells can become encrusted with minerals that impedes water flow. Rehabilitation can involve cleaning by mechanical methods or a combination of mechanical and chemical techniques. Dislodging encrustation by brushing, scraping and then removing it by bailing or pumping is typically followed by acidizing to dissolve remaining encrustation. Analysis of pumping tests performed before and after treatment is the only way to evaluate the effectiveness of a well rehabilitation.
