What exactly does Resonflux clean? +
We target restricted flow in the rock surrounding the producing or injection interval. Oil must pass through tiny spaces in that rock to reach the well. This service is different from repairing a pump or removing large debris from inside tubing.
Is the Wave Generator a product or a service? +
The Wave Generator is the downhole tool. The service starts with reviewing your well, designing the generator and treatment, planning field deployment and measuring the response. The scope and equipment responsibilities are defined for each job.
Which wells are good candidates for vibration-resonance treatment? +
The one key precondition is a positive skin factor on the target interval, indicating contamination of the near-well zone that restricts flow. The technology works on both production and injection wells: vertical, deviated and horizontal, onshore and offshore.
Are there restrictions on reservoir type or depth? +
The record includes different reservoir types and well geometries. Each application still needs an assessment of formation damage, completion, tool access, temperature, pressure and fluid compatibility. There is no universal approval for every depth or reservoir.
How long does a treatment take? +
Active treatment of a near-well zone typically runs 4–8 hours. This is not the total shutdown time: setup, deployment, tool recovery and restart must also be counted. For horizontal wells, duration scales with the length of the horizontal section. Injection wells can also be stimulated continuously for 1.5–2 months using the well’s existing injection pressure.
Do you need to shut the well down? +
Not always. With coiled tubing, the wave generator is lowered inside the production tubing to the perforation zone, so selected gas-lift wells can be treated while producing when the completion and operating plan permit it. This approach was used at Prudhoe Bay (Alaska) and on a North Sea platform.
What equipment and crew are required? +
Standard oilfield equipment ordinarily used for well washing, operated by the field’s own workover crew. The wave generator is designed for the target well. Equipment, crew, mobilisation and other job costs are established in the treatment scope and quotation.
What results can we realistically expect? +
Across ~1,000 wells and 30+ years, the documented success rate is 65–70%, with an average +40% oil production on producers and +45% injectivity on injectors. These historical results describe different wells; they do not predict your well’s response. An individual assessment is required.
Are any chemicals injected into the formation? +
No. Fresh water is the only working fluid. The cleaning effect comes from resonant acoustic stimulation (physics, not chemistry), without adding acid or chemical cleaning reagents. Returning fluid still needs appropriate handling.
What data do you need to evaluate a well? +
Useful data includes: skin factor (if known), formation lithology, well-log data, perforation intervals, oil density and viscosity, formation pressure, production history for the last 1.5–2 years (or injection rate and pressure for injectors), dynamic fluid level, and the type of downhole equipment. Partial data is fine. Send what you have.
Can the treatment damage the well or the formation? +
The target interval, equipment limits, working fluid and operating pressures must be reviewed before treatment. The method uses controlled circulation and vibration, but it should not be treated as risk-free. The engineering plan needs to address the actual completion and reservoir conditions.
