ESP Fallback Challenges

Sand Fallback​

  • During shutdowns, sand will fall and collect in the stages of the ESP​

Can cause instant failures ​

  • Potential to lock pump or break the shaft, preventing restart- requires immediate workover​

Causes stage degradation due to sand wear​

  • Reduced head​

  • Poor gas handling​

  • Hotter equipment temperatures​

Increased prevalence of 100 mesh sand (.006" diameter) makes this all more damaging​

SAND-X Advantages During ESP Shutdown

Equalization​

SAND-X has a patented lower end, "Sand Stop," that allows fluid to flow through the restrictor while simultaneously separating the sand, thereby allowing clean fluid to backflow through the ESP.​

Fallback​

SAND-X has a large internal chamber capable of housing the sand during the equalization and fallback phases. These stages provide a defense against pack off and support the sand in preparation for flushing it out during restart.​

Restart​

During restart, fluid flow now reverses direction and begins to flow up the tool. The patented lower restrictor functions as its own clean system. Since the stages had already eliminated the risk of pack off, the patented lower assembly and chamber act in concert to flush out the sand and ensure the ESP can return to full production.​

 sand-x FAQs

  • 99% efficiency separating 100-mesh sand during our latest pressure testing

    • Everything is 100% 13Chrome (high strength SS)

    • Double O-ring design on top and bottom of housing mimics ESP best-practices

  • SAND-X will help clear gas for restarts

  • 80 cups of sand

  • Two separate Lab and Field Tested Patents on SAND-X:

    • The Restart Stages on the shaft break up sand in the chamber during restart. When the tool fills up with a column of sand, the Restart Stages break up the bridge and allows the tool to flush completely in three seconds.

    • Sand Stop prevents sand from passing into the ESP during Equalization and Fallback. Sand Stop is a bypass for fluid.

  • Yes:
