Screen & Perforation Jetting
High-pressure rotating jetting to blast away calcium scale, iron bacteria, and mineral encrustation from casing perforations and well screens.
Common Signs & Symptoms of Failure
- ⚠ Well yield has gradually declined over several seasons despite strong regional aquifer
- ⚠ Significant drawdown occurs almost immediately after pump start
- ⚠ Red-brown or black slime (iron/manganese bacteria) visible in pipes
- ⚠ Heavy calcium carbonate scale visible on pulled pump and pipe threads
Technical Execution & Equipment Standards
- ✓ 360-degree rotating high-pressure water jetting tool at 3,000+ PSI
- ✓ Hydraulic scrubbing of continuous-slot stainless screens and mill-slot perforations
- ✓ Simultaneous vacuum or airlift recovery to immediately discharge dislodged scale
- ✓ Eco-safe NSF-approved sequestering agents to dissolve hardened calcium carbonate
- ✓ Pre- and post-jetting video camera inspection to verify open intake channels
Equipment Specifications: Features custom rotating multi-jet stainless heads, high-pressure braided hydraulic hose, industrial pressure washers, and downhole video monitoring.
Our Step-by-Step Field Process
1. Pre-Jetting Video Inspection
We deploy our downhole camera to inspect the perforations or screen slots, identifying whether the obstruction is biological iron slime, mineral scale, or collapsed formation sand.
2. Chemical Pre-Treatment (If Indicated)
For severe calcium carbonate encrustation, we inject NSF-approved food-grade acidic sequestering agents to soften mineral bonding before mechanical jetting.
3. 3,000 PSI High-Pressure Rotary Jetting
Our specialized rotating nozzle shoots high-velocity water streams horizontally against the casing slots, scrubbing mineral crust from both the inside and outside face of the perforations.
4. Borehole Flushing & Flow Verification
We airlift all dislodged debris out of the well and run a sustained pumping test to document recovered GPM flow and decreased drawdown.
Edwards Aquifer & West Texas Geology
The limestone groundwater of the Edwards-Trinity Plateau is mineral-saturated. As water transitions from rock into casing, pressure drops cause calcium carbonate to precipitate directly onto the casing slots, suffocating water flow over time.
Preventative Maintenance Tip for Landowners
If your well yield has declined by more than 20% over three years, perforations are likely scaling over. Jetting can restore original yield before the rock pores seal permanently.
Frequently Asked Questions
Is high-pressure jetting safe for older well casing?
Yes, when performed by a licensed professional. We inspect the casing with our downhole camera first to ensure wall structural integrity, then calibrate jetting pressure precisely to strip scale without damaging metal or PVC slots.
Will jetting improve my well's GPM yield?
If your low yield is caused by mineral clogging rather than a depleted aquifer table, jetting frequently restores flow back to the well's original post-drilling production rates.
