Process

Three steps
One powerful result

AirShock works in screened and open-hole wells of any depth. Just lower, fire, and raise.

01

Lower the AIG

The AirShock® Impulse Generator is lowered into the well via hose reel to the treatment zone — whether at the screen, gravel pack, or open formation.

02

Activate & Pulse

Open the surface gas valve. The AIG automatically fires at 15–25 pulses per minute, generating powerful shock waves and oscillating bubbles that penetrate deep into the formation.

03

Raise & Restore

Move the tool up through the screen in controlled intervals. Mineral deposits, biological accumulation, and obstructions are dislodged — often restoring wells beyond original capacity.

Technology

Built for the field
Engineered to outperform

Shock Wave Generation

Precision-controlled bursts of compressed nitrogen or air create high-energy shock waves that penetrate well screens, gravel packs, and surrounding aquifer zones simultaneously.

Oscillating Bubble Action

Expanding and contracting gas bubbles force water in and out of the formation — mechanically dislodging incrustation and biofouling that chemicals alone can't reach.

Surface Pressure Control

Operators adjust gas pressure from the surface in real time — from 225 to 3,000 psi — without interrupting treatment or pulling the tool.

Chemical Synergy

When used alongside acid or other chemical treatments, AirShock creates vigorous agitation that accelerates incrustation dissolution — dramatically reducing chemical volumes required.

Hose Reels

State-of-the-art hose reels

Flow Industries designs and builds the high-pressure hose reels that run AirShock into the well. When the market had nothing tough enough for our customers, we engineered our own — manual, hydraulic, or electric drive, in any hose length. Today they’re supplied across drilling, marine, military, aviation, and industrial applications.

Proven Results

Numbers that speak
for themselves

Real-world outcomes from drilling contractors and water authorities across six continents.

100%+

Water Well Specific Capacity Restoration

Wells consistently restored to full specific capacity — often exceeding original design performance.

675%

Remarkable Recovery

A well declined to 25% of original capacity was restored to 675% — delivering 169% of its original design specific capacity.

10min

Obstruction Cleared

Gravel pack bridge in Bolivia cleared in 10 minutes — after 10 days of traditional methods failed.

0%

Sanding Eliminated

A heavily sanding well in Wisconsin was treated with AirShock Gravel Stimulation — sanding reduced to 0%.

Before AirShock treatment Before

Flow severely restricted by mineral buildup at the screen

After AirShock treatment After

Screen completely cleared after a single AirShock treatment —
capacity fully restored

I am pleased, not only with the results we have achieved with AirShock, but how easy it is to setup and apply.

3 wells → 90%+ capacity · 1 well → 141% capacity

Technical Director · Layne Christensen, Inc., USA

We got incredible results with AirShock. We increased the specific flow for about 400% — from 30 lps at 70m to 74 lps at 42m.

AirShock made in 10 minutes what traditional techniques like jetting, surging and airlift could not do in 10 days. Very impressive.

Results with and without AirShock are as different as day and night. With AirShock I am getting fantastic results.

Well F2 increased from 3.5 to 55 m³/h/m with only 600 kg acid. The AirShock dramatically reduced the chemical volume we needed.

F1: 5→29 · F2: 3.5→55 · F3: 7→50 (m³/h/m)
