Clean Well

Technology of well bottomhole normalization with proppant plugs after hydraulic fracturing in 1 well operation

Application area

• During performing current and workover of wells

• During performing bottomhole cleaning operations after hydraulic fracturing in vertical, directional and horizontal well

Technological process per 1 well operation

• Layout descent

• Proppant plug

• Drilling out the proppant plug and extracting the proppant through the layout

• Layout lift

Advantages of the technology Clean Well

  1. Drilling and cleaning of proppant plug in 1 well operation without creating circulation

  2. Treating of lost circulation wells

  3. Works with hard-to-destroy deposits at the bottomhole

  4. Reduction of well input time by putting into operation

  5. Work in wells with low formation pressure

  6. No negative impact of flushing fluid on the formation
