It is a common situation for water wells to lose their capacity or experience water quality problems that need fixing. One of the appropriate ways of dealing with such a situation is carrying out well rehabilitation. Generally, these problems result from fouling items that become deposited on the water surface. As a result, the wells may lose capacity while the water quality is also likely to deteriorate in odor and taste.
The water may also become discolored or get affected by bacteria. Through a restoration process, however, the well can regain its functionality. The increased level of lost capacity and the need for cleaning or treatment results from the presence of deposits in the water. This is therefore done to maintain the pore volume of gravel pack in the hole.
In order to restore the volume of pore and quality of water, rehabilitation should be conducted in a proper way. This, therefore, requires that the process should be conducted using different methods. In order to ensure the effectiveness of the rehabilitation process, proper identification of both the solvent and plugging material must be done. The removal of plugging deposits requires physical or chemical treatment.
Dissolving the plugging material is a demanding task due to the complexity and variability of the microbiology and geochemical environment of the bottom of the well. This task also requires the user to rely on a particular combination of the chemicals used to remove the plugging material. Removal of the deposits should be done with a lot of care in order to preserve the construction of the hole.
Some of the methods of rehabilitating wells include; chemical application, brushing, dual swabbing, sonar jet, aqua freed, bore blast, and jetting. The use of chemicals involves having a set of strategies in line with the problem cause, well construction and the type of formation. The chemical solution should be effective in deposit removal, penetration to the surrounding formation and improved agitation.
Normally, brushing is considered a pre-treatment in the restoration process. It is used for removal of the byproducts of corrosion and mineral deposits. It opens up the screened area to allow penetration of the chemicals. Dual swabs, on the other hand, allow allocation of zones for placing chemicals. Additionally, it improves the agitation and energy level for dispersion of chemicals together with facilitating the reaction of acids and mineral deposits.
High pressure jetting can also be used for the opening of the screens. A sonar jet, however, assists in the removal of mineral deposits. A bore blast is also a crucial rehabilitation tool that is used to provide energy that initiates the breaking of the deposits in the well. It can also be used in collaboration with other chemicals.
Another treatment method for restoration involves the use of aqua feed. It is an injection of liquefied carbon (IV) oxide, which has the ability to expand into a gas. Through expansion it provides energy for breaking the gravel pack, formation and screen. The expansion also enhances further penetration into the well formation. These are therefore some of the services Wisconsin restoration companies offer.
