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.
