The questions below are the ones contractors, utilities, and water-services companies actually ask us. Short answers here; each links to the full technical page.
Each method delivers energy to a different place. Brushing and jetting clean the inner screen surface; chemicals dissolve what they can reach; impulse treatment sends pressure waves and a surging water motion through the screen into the gravel pack and near-wellbore zone — where most plugging actually sits. The methods are often complementary rather than competing. Full comparison: Impulse vs. high-pressure jetting · Why wells lose yield.
Yes — PVC wells demand specific attention, and AirShock® has two dedicated approaches for them: very small impulse generators (from 1.2" to 1.8") whose pulse energy is matched to PVC construction, and a special device that directs the discharge downward, preventing direct firing at the casing and screen. The right configuration is chosen from the well's construction data. (A PVC well from our documented archive was treated and restored — see the case studies.)
Yes. The pump is removed before treatment so the tool can reach the screen interval, and reinstalled afterward for the post-treatment pump test. This is standard practice for well rehabilitation generally, whatever the method — the before/after step-drawdown tests around it are also how the result is honestly measured.
Project pricing is set by the contractor who performs the work — it depends on the well, the site, and the local market, and it is the contractor's business, not ours. Flow Industries supplies the equipment: the impulse generators, hose reels, and training. If you are a contractor evaluating the equipment itself, contact us for a quotation.
Nitrogen in most cases: it does not oxidise or feed aerobic bacteria in the well, and it is available anywhere in standard bottle racks. Consumption is simple arithmetic — receiver volume × pressure × shots — and a typical 100-ft screen rehabilitation runs on one standard bottle rack. The full logic, a worked example, and the pressure-by-depth guidance: Planning gas supply.
A crew of 2–3: one on the reel, one on the gas manifold, with airlifting/bailing between passes. The system transports on a small trailer or pickup and sets up in under an hour. How a treatment pass actually runs: Planning gas supply.
The tool diameter is selected against the well's diameter and screen type, and the working pressure against depth and condition — the receiver, ports, and size are engineered as a set to shape the pulse, not just to raise a pressure number. The physics: The physics of impulse cleaning. For a specific well, send the construction data and we will recommend the model and settings.
You buy the equipment and own it — no royalties, no minimum fees, no per-job charges, no annual license, and no growth quotas. Flow Industries trains your personnel on operation and safety, and supports your first jobs. Spare parts and additional units are supplied from stock as your work grows. Contact us to discuss the right configuration for your operation.
Have a question that isn't here? Ask it — the honest answer, including "it depends on the well," is one message away.
