Sealing solution with depth controlling capabilities

BackStop service is a shallow-penetration polymer gel slurry system for water and gas shutoff applications. This diverse water conformance control system provides an alternative to conventional cement squeeze treatments. 

Unique chemistry for controlled placement

BackStop key features:
  • Slurry is injected into all open perforations, so no need for zonal isolation as with standard sealant jobs
  • Shallow penetration of the filtrate allows for reperforation in the hydrocarbon zone
  • Unlike cement, the BackStop slurry remaining in the hole does not require drilling out; simply jet it out with coiled tubing
  • Longer and hotter intervals can be treated in one day, using the time allotted for wash out for placement instead
