SandMaze – Extend the life of your ESP
SandMaze – Extend the life of your ESP
PetroQuip’s SandMaze captures sand, proppant and debris fallback during production shutdown. The proprietary flow path design captures the sand in holding chambers when the ESP is offline which prevents sand from settling on top of or in the pump’s stages. Once a flow is re-established, the SandMaze’s self-cleaning feature allows sand to re-enter the production flow stream. The cleaning action does not require the sand to be jetted out of the sand chambers which significantly reduces the risk of cutting through the outer chamber of the tool.
Watch how our SandMaze and SandStorm-E work together:
See a timelapse of SandMaze in action:
- Extends the life of the ESP by minimizing hard pump start scenarios due to sand settling on top of the ESP
- Bi-direction flow allows for injection treatments
- Captures sand when the ESP is offline preventing sand settlement on pump
- Automatic self cleaning feature based on gravel pack screen technology
- No communication to the annulus
- Sand re-enters the production flow stream when the pump is back online
- Minimizes erosion issues to the outer body of the tool
When an ESP is shutdown, solids suspended in the production stream in the tubing above the ESP settle on top of the ESP pump after it’s shut down and flow stops. The sand often settles on top of or gets lodged inside the ESP pump’s stages. When the ESP is restarted, this often creates a “hard start” to get the sand moving again which overstresses the motor and shortens the pump life. Additionally, it accelerates pump wear, both of which cause premature pump failures.
The SandMaze not only protects pumps from permanent damage due to solids fallback, but also significantly increases an ESP’s run time in unconventional applications. Once flow is resumed, the sand chambers self-cleaning feature (which is based on standard gravel pack screen design) allows the captured sand to re-enter the production flow stream. The cleaning action does not require the sand to be jetted out of the sand chambers (as the current models on the market do) which significantly reduces the risk of cutting through the outer chamber of the tool.
