SandMaze

Capture fallback and extend the life of your ESP.

PetroQuip's SandMaze keeps sand out of your ESP by capturing sand, proppant, and debris fallback during production shutdowns. The proprietary flow path design directs particles into holding chambers when the ESP is offline, preventing sand from settling on or in the pump's stages. Once flow is re-established, SandMaze's self-cleaning feature allows captured sand to re-enter the production stream without aggressive jetting. Designed for ESP wells with frequent sand-related failures.

Case Study: Delaware Basin ESP Fallback Prevention

PetroQuip’s SandMaze outlasts a competitor fallback tool adding up to 420 days of ESP run life in the same wellbore.

Challenge

A major Delaware Basin operator was losing ESPs to sand fallback during shutdowns. As pumps sat idle, sand settled onto the stages and created hard-start conditions that triggered premature failures. A competitor fallback tool failed to solve it. To run a clean comparison, the operator pulled the competitor tool and installed SandMaze in the same wellbore: same well, same formation, same conditions, with only the fallback tool changing.

Solution

SandMaze captures sand in proprietary holding chambers as the pump shuts down, then gently reintroduces it on restart. No jetting, no hard starts, no stage damage, and no moving parts. The tool flows bi-directionally and is chemical-injection capable, so it protects the ESP without restricting operations. Results were tracked against an operator-maintained ESP install/pull tracker covering 274 installs.

Results

Up to 420 additional run-life days versus the competitor tool in the same wellbore

✓ 1,855 cumulative run-life days added across seven head-to-head sample wells

✓ 264-day average run-life increase per well

✓ 652-day longest active run and counting

✓ 5 of 7 wells are still running

How it works:

SandMaze operates through four distinct phases that provide continuous ESP protection throughout the production cycle.

Production Mode:

  • Normal fluid flow through the tool during ESP operation

  • Sand particles flow through without restriction

STAGE 1

ESP Off / Sand Captured

  • When ESP shuts down, sand settles into holding chambers

  • Prevents sand accumulation on pump stages

STAGE 2

ESP Restart / Sand Flushing

  • Self-cleaning feature activates when production resumes

  • Captured sand safely re-enters production stream

  • Tool returns to normal production mode

  • No aggressive jetting required
