KAC President
Water and environmental specialist.
In order to strengthen our global expertise, KAC teamed up with WellJet an American company with extensive experience in the maintenance and development the water wells where they use state-of-the-art well rehabilitation, special techniques which contributes to increase our ability to provide high-quality service.

3. Sector-Disruptive Techniques for Well Development & Rehabilitation
Patent No. US (8,312,930 B1) is the world’s most advanced and effective method for water well development and rehabilitation delivering unprecedented water-yield, well infrastructure restoration and energy savings for its clients. This technology can effectively:
remove obstructions from inside casing.
open perforations, and break down harmful deposits in gravel pack.
and, near-wellbore formation.

4. Diameter capabilities: 5cm – 1.8m
The Technology
WELLJET utilizes an array of custom-built, high pressure self-rotating nozzles that deliver laminar streams of water downhole at up to 20,000 psi – breaking even the toughest bonds between obstructions, the well screen and the filter zone.
Pressure: up to 1,400 bar
Depth range: down to 600m
Diameter capabilities: 5cm – 1.8m

5. KAC-WELLJET ‘‘Game Changer’’

6. Representative Flow increases

7. Slashes Energy Cost & Reduces CO2 Emissions
WellJet has been shown to reduce extraction pumping costs by as much as 75%
Representative energy savings

8. Extends equipment lifecycle
A successful rehabilitation removes physical, and chemical fouling from (1) well screens, (2) gravel pack, (3) remove residual fluids/ mud from borehole wall in order to (4) decrease the drawdown, increase groundwater inflow while lowering pumping energy costs, and increasing the life of the well and pump.

9. Zero environmental impact
WELLJET uses nothing but water, pressure and our patented technology – water to obtain water. Nothing could be simpler, safer or more effective.

11. Wellfield Rehabilitation Case Study
Wells drilled cm diameters. Total depths m.
Original performance averaged 100 m3/hr.
By the time of rehabilitation, performance had declined to an average of 58 m3/hr –
a production loss of 42 m3/hr per well – 42%.
Prior rehab attempts had failed to restore production.

12. BEFORE AFTER

13. Well Performance comparing to 1991

14. Well Performance Comparing to Pre- Rehab

15. JPMC WELLS NOW PRODUCING MORE WATER,MORE EFFICIENTLY, AND CONSUMING LESS ENERGY, THAN IT DID WHEN IT WAS BRAND-NEW 25 YEARS AGO   
The total increase of JPMC 21 Wells after KAC/ WellJet patented technology in development and rehabilitation Approximately :
650 m3/ hour
15,600 m3/ Day
468,000 m3/ Month
5,616,000 m3/ Year
