Shock-assisted cementing for wells you can’t afford to lose.
In HPHT wells, sour-gas wells, CO₂ storage wells and other critical applications, cement quality directly controls long-term well integrity. Poor mud displacement, micro-annuli and channeling can lead to gas migration, sustained casing pressure and expensive remedial jobs.
AirShock® Cement Assist uses controlled downhole pressure pulses during or immediately after primary cementing to improve annular cement placement and bonding.
How it works:
- An AirShock® tool is run inside the casing near the primary risk interval (gas zones, thief zones, critical barriers).
- During or immediately after cement placement—while the slurry is still mobile—nitrogen is pumped to the tool.
- The tool generates cyclical high-pressure pulses in the fluid column, which:
-Vibrate the casing and near-wellbore region
-Help break up gel structures and prevent early channeling.
-Drive cement into irregularities, micro-crevices and washed-out sections.
-Assist mud-cake removal and improve casing–cement–formation contact.
The result is a denser, more uniform cement sheath and improved zonal isolation in the zones that matter most.
Typical applications:
- HPHT and sour-gas wells with strict integrity requirements
- CO₂ injection and storage wells requiring long-term containment
- Multi-zone wells with complex pressure regimes and history of channeling
- Sections where gas migration or sustained casing pressure has been an issue
Key benefits:
- Improved bond quality in critical intervals (verified with cement evaluation logs)
- Reduced risk of gas migration and SCP, lowering the need for remedial squeezes
- Stronger primary barrier integrity for high-consequence wells
- Seamless integration with standard cementing practices: AirShock® is an add-on, not a replacement
- Regulatory and ESG support by improving long-term well containment
