How the Sand Flushing Unit Works

Step-by-step oilfield sand cleanout process — fast, safe, and highly effective.

1
Site Assessment & Mobilization
Review well data and mobilize the self-contained unit to the well site — ready to operate within hours.
2
Wellhead Connection & Rigging Up
Connect high-pressure lines to the wellhead and return flow line to the annulus. Pressure test all connections.
3
High-Pressure Pumping & Sand Displacement
Engage the triplex plunger pump. High-velocity fluid jet dislodges and suspends sand for circulation out of the wellbore.
4
Reverse Circulation & Sand Recovery
Sand-laden fluid returns to surface through the annulus and is directed to solids control equipment for separation.
5
Progressive Cleanout & Final Verification
Advance work string as sand is removed. Perform final high-volume flush until returns are clean. Rig down and demobilize.
Typical cleanout time: 4–12 hours per well (vs. 2–5 days with workover rig)

Applications — Where Our Sand Flushing Unit Delivers Results

🛢️
Onshore Oil & Gas Wells
Mature fields with sand production causing wellbore fill and reduced flow rates.
🪨
Shale & Horizontal Wells
Proppant flowback and sand accumulation in laterals — cleaned with coiled tubing integration.
🔧
Workover & Completion Operations
Pre-intervention cleanout before installing pumps, packers, or running new completions.
💉
Injection & Disposal Wells
Maintain injectivity by removing sand accumulation in water/gas injection wells.
🌍
Geothermal Wells
Restore thermal output by clearing mineral scale and sand in geothermal systems.
📡
Well Testing & Evaluation
Ensure accurate test data with a clean wellbore before pressure and flow measurements.

Sand cleanout campaign planning

Check transport and return handling

Provide well geometry, estimated solids loading, available circulation paths and the pressure limit. Evaluate whether the proposed flow can carry solids to the surface without exceeding the operating envelope.

Measure the cleanout outcome

Track returned solids, circulation losses, pressure and the post-cleanout condition. Compare job duration and total mobilization cost against the same well scope rather than assuming a fixed saving.

Frequently Asked Questions

What is the maximum pressure and flow rate?
Standard configuration delivers 35 MPa (5,076 psi) maximum working pressure and 600 L/min (158.5 GPM) flow rate. Custom higher-pressure configurations are available.
Can it be used with coiled tubing?
Yes. Fully compatible with coiled tubing for horizontal and extended-reach wells. Optional adapter kits and chemical injection pumps available.
How long does a typical cleanout take?
4–12 hours per well depending on depth and sand volume — dramatically faster than 2–5 days with a conventional workover rig.
What is the lead time?
Standard units: 45–60 working days. Custom configurations: 60–90 working days. We provide regular progress updates with photos.
What after-sales support do you provide?
24/7 technical hotline, rapid global spare parts shipping, on-site commissioning, operator training, and preventive maintenance programs.
