SandBOND™ Breaks the Cycle of Sand-Driven Pump Failures in Long-Lateral Horizontal Wells

Williston Basin wells extend pump run life 5.5× and 4.7× with zero production loss after a single bullhead treatment; both pumps continue to operate beyond one year

HOUSTON, Oct. 14, 2026 /PRNewswire/ -- TenEx Technologies today announced extended field results demonstrating SandBOND™'s ability to control severe proppant production and protect downhole pumps in long-lateral horizontal wells without sacrificing production.

Chord Energy, a Williston Basin operator, was looking to further decrease pump failures caused by severe proppant production in approximately 10,000-ft lateral wells. Following a single SandBOND™ treatment in two wells, both wells have now operated for more than one year without a sand-related pump failure, with both pumps continuing to run with stable performance.

Field Results:

• Zero pump failures in both treated wells
  
  
• More than one year of continuous pump operation following treatment
  
  
• Zero production loss and 100% regained permeability
  
  
• No intervention rig, workover, or specialized equipment required
  
  
• Simple bullhead treatment followed by a 24-hour soak

"Sand-driven pump failures have been a persistent challenge in long-lateral horizontal wells across the industry," said Miguel Peña, CEO of TenEx Technologies. "These results demonstrate that SandBOND™ can break that cycle with a simple, low-complexity treatment while maintaining production. More than a year after treatment, both pumps are still running."

SandBOND™, a non-resin, atomized aluminum-based sand-control technology, is designed to control proppant production while maintaining well productivity. The treatment is bullheaded directly into the well, followed by a 24-hour soak, with no intervention rig, workover, or specialized equipment required.

"The combination of sustained pump performance and zero production losses is particularly significant," said Amr Radwan, Co-Founder and CTO of TenEx Technologies. "These results demonstrate that SandBOND™ can control proppant while allowing the well to continue producing effectively."
