The process involves creation of a shock wave and oscillating gas bubble after each pulse resulted in removing hardened scale and biological build-up from the screen, gravel pack and surrounding area. The shock wave breaks up the scale on the screen, while the expanding and contracting bubble forces water in and out of the gravel pack and aquifer ensuring a comprehensive washing process. In a very short time, a well is completely restored to the original level of efficiency. The method is unique both in success and ease of setup and operation.
AIRSHOCK® impulse technology provides a highly effective solution for cleaning and rehabilitating under performing water wells. The process utilizes an AIRSHOCK® Impulse Generator (AIG) to provide high-pressure pulses of compressed gas to remove build-up from well screens, gravel packs and open hole formations, providing unparalleled efficiency in rehabilitation and development of all types of wells.
The success comes from concentrating each pulse of energy per blast. The AIG fires automatically once every 2 - 3 seconds and each pulse lasts just several milliseconds. Resulting shock waves and powerful water surges, produced by the process, successfully remove encrustation, slime and scale. This not only cleans the well, but also improves the production output of the formation. In a short period of time the well is completely restored to the highest level of efficiency.
Based on past performance, the results are long-lasting and nearly every well is restored to 80% to 120% of its original performance.
