摘要

Water well maintenance is a broad topic and a term used to encompass all manner of work performed on troubled well systems. One of the more common methods used in well maintenance is the combined use of chemicals and mechanical agitation to target fouling present downhole. Chemicals are used in water well rehabilitation to facilitate the removal of fouling mechanisms that can impact the production capability of well systems, reduce well efficiency, and contaminate or degrade the well system in some manner. Contamination can be the result of chemical infiltration into the well environment or the appearance of bacteria, viruses, or other microorganisms. Well fouling can be caused by mineral and biological buildup as well as sediment migration, each individually or combined impacting the screens, pump intake, pore spaces of the gravel pack, and near-well formation.
