Description: Well #5; 18 inch by 487 feet, open hole, basalt formation.
Problem: Video showed heavy iron buildup, unable to see where well casing ended. Lost production gradually over 20-year period with no maintenance.
Treatment: Wire brushed well casing to 300 feet. Aqua Freed treatment, 17,000 lb of CO2.
Yield: New: 500 gpm Pre-Treatment: 200 gpm Post-Treatment: 750 gpm
Percentage Improvement: New: 50% Post-decline: 275%
Notes: City mainlines apparently very dirty. Residual CO2 pumped from well caused release of these deposits into the system.
Description: Well #2; 8 inch by 305 feet; 25 foot stainless screen. Sand and gravel formation.
Problem: Declining yield due to calcification and iron bacteria. Primarily calcification.
Treatment: Aqua Freed treatment, injected 3,2oo lb of CO2 in two locations.
Yield: New: 250 gpm Pre-Treatment: 100 gpm Post-Treatment: 400 gpm
Percentage Improvement: New: 60% Post-decline: 300%
Notes: Significant improvement due to superior formation cleaning.
Description: Commercial 8″ x 263′, 15′ stainless screen; seabed formation.
Problem: Lost production due to mineralization and slime bacteria plugging. Continuous declining production and strong odors.
Treatment: Aqua Freed treatment
Yield: New: 50 gpm Pre-Treatment: 30 gpm Post-Treatment: 100 gpm
Percentage Improvement: New: 100% Post-decline: 233%
Description: Well #2, 4″ x 247′ perforated casing; broken basalt formation.
Problem: Declining well, finally failed completely. Perforations plugged. Pump stuck in perforated zone.
Treatment: Injected acid (Unicid) to release pump, wire brushed entire well, Aqua Freed treatment.
Yield: New: 25 gpm Pre-Treatment: 4 gpm Post-Treatment: 30 gpm
Percentage Improvement: New: 20% Post-decline: 650%
Description: Well #12; 12″ x 166′, 35′ of 10″ stainless screen; 20″ borehole, gravel packed.
Problem: Declining yield due to heavy iron bacteria. Four other wells on the site had previously been abandoned due to plugging.
Treatment: Aqua Freed treatment, injected 3,900 lb of CO2.
Yield: New: n/a Pre-Treatment: 250 gpm Post-Treatment: 400 gpm
Percentage Improvement: New: n/a Post-decline: 60%
Notes: Pump motor close to burning out due to heavy coating of iron bacteria preventing cooling. Pump column plugged and unusable.
