  • Flushby unit truck mounted rig for sand washing operation

    Flushby unit truck mounted rig for sand washing operation

    Flushby unit is a novel specialized drilling rig, primarily employed for sand washing operations in screw pump-heavy oil wells. A single rig can accomplish the traditional well-flushing tasks that usually require the collaboration of a pump truck and a crane for screw pump wells. This not only enhances efficiency but also reduces the need for additional auxiliary equipment, thus lowering operational costs.
