AIRSHOCK® is a patented, non-destructive and environmentally friendly technology for oil, gas, injection and water well stimulation and cleanout. AIRSHOCK® is extremely effective for all types of vertical and horizontal wells, both open and cased hole.
AIRSHOCK® is based on the compressed gas (air or nitrogen) continuous accumulation and its repeated sudden pulsing release in the well by means of the AIRSHOCK® guns. The AIRSHOCK® guns provide unparalleled efficiency in formation permability enhancement and cleanout of all types of oil, gas and injection wells. (see a demonstration of Airshock® Gun firing).
When the AIRSHOCK® process is in progress, shock waves break up any type of formation damage, while the expanding and contracting bubbles force fluid in and out of the formation ensuring a comprehensive stimulation process. Energy losses are minimal so that AIRSHOCK® delivers maximum energy downhole and directs it exactly at the target zone. AIRSHOCK® is simple to setup and operate.
When applied along with fluid injection, AIRSHOCK® makes injection of heavy and viscose fluid much easier and prevents the fluid from following the paths of the least resistance.
Phase I, first 5-15 msec: the AIRSHOCK® Gun is downhole and is firing against the perforations: sudden high-pressure gas release from the Gun internal chamber creates a powerful shock wave. The shock wave is followed by a rapidly expanding gas bubble that generates a short fluid surge into the perforations. The shock wave and the fluid surge break the debris and scale.
Phase II, next 50-70 msec: The gas bubble immediately starts contracting creating a strong flow back into the well and washes out the crushed debris and fines. The expanding and contracting process repeats itself several times until all energy is spent.
This process continues as long the gas supply to the AIRSHOCK® Gun is open and the tool is firing.
