Once the screen, gravel pack, seals and backfill have been installed, the well is developed (flushing). This development aims at repairing the damage done to the aquifer during drilling, because of the additives which were been used during the drilling process, also to remove some of the small silt and sandy particles from the borehole.
The use of over pumping as a mean of development is not advocated since it only increases permeability in zones which are already permeable. Instead we recommend mechanical surging with a plunger or the use of air or water jetting which physically agitates the gravel pack and adjacent aquifer material. This is an extremely efficient method of developing and cleaning wells.
