High Pressure Jetting System
The most commonly used method to kill and remove bacteria from a well is to saturate it with a high concentration of chlorine. Research has recently confirmed that this method only affected the “outer” layer of the bacterial slime known as biofilm by causing a chemical burn that forms a hard crust. This crust protects the underlying layers, which entails making cleaning even more challenging. The keys to an effective well rehabilitation are:
- To break up the biofilm and mineral deposit by penetrating both the inside and outside of the screened interval
- Then with pH adjusted chlorination, kill the bacteria, and then remove this material
Mineral deposits routinely require mechanical and chemical cleaning to remove layers of scale, rust, and other deposits that form on the inside and outside of the well and within the gravel pack. Brushing the inside of the well is the most common method of removing these deposits but the downside of this method is that it only removes some of the minerals on the inside, the outside of the well is left untouched. Chemically treating these minerals is a slow and costly effort.
Why do it?
High-Pressure Jetting can be used as an alternative to chemicals that will deteriorate pipes. Over time a well will lose production and efficiency due to congestion in the screened or slotted zones in a well. This congestion is a result of bacterial sludge, mineral deposits, silt, and clay, but usually, it will be a combination of 2 or more of these factors. These common cleaning methods do a fair job, at best, of removing these congesting materials. With Hydro’s new High-Pressure Jetting service you will receive a superior job of removing these obstructing materials.
