Powerwave well stimulation system was developed for improved oil recovery by stimulating a well using powerwave oscillator tool to create pulsating pressure wave that break up and remove any type of near wellbore damage.
- 3,600 ft, 10” ID, Waterflood injection line packed with Barium Sulfide Scale cleaned in one run.
- Patented Powerwave Oscillator is run on coiled tubing or on jointed pipe when a rig in on well.
- Fluid can be acid, water, seawater, diesel, solvent , nitrified fluids, etc.
- Proven Cost-Effective Process for treating near-wellbore and perforationdamage, removing scale build-up and stimulating poduction and injection.
- Used succcesfully to treat over 6,500 wells in 26 states and 37 international areas.
- Effective results in both vertical and horizontal wells including oil, gas, geothermal, water and CO2 Injection, disposal and monitoring wells.
- Wells successfully treated from 90 ft to 27,000 ft deep and temperatures up to 750 deg.F
Specific Applications
- Removal of scale deposits from tubing, casing and near wellbore area
- Primary stimulation of high permeability formations
- Preparation prior to stimulation treatments
- Preparation for gravel packing or frac packing
- Alteration of injection profiles
- Correct placement of treating chemicals

Case History
Texas : Wolfcamp Formation Well
Production jumps from 6 bopd to 250 bopd
Scale and paraffin problems had lowered production to 6 BOPD
Results: Six months after the Powerwave Oscillator Tool treatment, the operator reported that the oil production stabilized at 250 bopd
Colorado: Production Doubled from Desert Creek formation
Scale build up had caused production from this well to decline to 99 BOPD and 437 MCFD
Results: Damage was removed and production restored to the same levels as when the well was first completed, 425 BOPD and 865 MCFD
Indonesia – Oil Well, South Sumatera: Production Increased after Powerwave Treatment
Background: The scale was indentified by water analyis from the well and scale build up around the perforations and tubing resulted decreasing in the oil production.
Treatment: The CT Powerwave tool was run in August 2018 to cleaning well up to the production interval of 5000 ft and to remove the damage surrounding the perforation tunnels then injecting the scale inhibitor for scale prevention.
Results: Damage was removed and production increased from 2000 bfpd/260 bopd/87% water cut to 3000 bfpd/720 bopd/76% water cut.
Six months after the Powerwave treatment, the operator reported that the oil production stabilized at 600 -700 bopd.
Indonesia – Geothemal Well, Central of Java
Production Increased after Powerwave Treatment
Background: The performance of the well shows the steam production has declined since the past period due to scaling
Treatment: The Powerwave tool was run with HWU/Snubbing unit in February 2019 to remove the scale surrounding the feed zones at 1760 m thru 2092 m. The fresh water was used as treatment fluid.
Results: As per target The steam production doubled after the treatment.
