Protect your most expensive wells with completion-focused AirShock® treatments.
Offshore and high-cost wells rely on complex completions—gravel packs, premium screens, open-hole liners—to deliver reliable, sand-free production over many years. When gravel packs loosen or screens plug, the consequences are severe: deferred production, risky interventions and high non-productive time.
AirShock® provides a non-explosive, nitrogen-driven pulsing solution to densify new gravel packs and clean existing packs and screens from the inside.
For new gravel packs – “Pulse-packed” completions:
After gravel placement, an AirShock® tool is positioned across the packed interval and activated:
- Pulses create oscillating pressure across the screen and gravel
- Gravel grains re-arrange and compact, reducing voids and weak zones
- Fines and loose particles are mobilized and flushed away
Result: a tighter, more uniform gravel pack with improved long-term stability and reduced risk of early sand production or screen damage.
For existing wells – screen & pack cleanup:
During a workover or planned intervention, AirShock® can be run on tubing or coiled tubing inside the completion:
- Pulses force fluid through screen openings and gravel pack
- Fines bridges, scale, wax/asphaltenes and other deposits are broken up
- Debris is mobilized into the wellbore for removal
The process can be combined with mild acids or solvents for additional chemical assistance, while relying on the pulses for intensive agitation and penetration.
Typical applications:
- Offshore or deepwater wells with gravel-packed or screened completions
- High-cost onshore HPHT or sour-gas wells where completion failure is unacceptable
- Wells with recurrent screen plugging or early sand-production incidents
Key benefits:
- Enhanced gravel-pack quality at installation for longer, more stable production
- Non-destructive screen cleanup without explosives or extreme surge pressures
- Reduced acid volumes and risk, thanks to strong mechanical agitation
- Lower intervention cost and risk compared to full recompletion
- Ideal for strict HSE environments: nitrogen-based, non-explosive, simple mechanics
