EquiSeal to solve horizontal water and gas shutoff 

EquiSeal conformance service is specifically designed to help control unwanted fluid production—water or gas—in horizontal or highly deviated wellbores. The stress-dependent rheological properties of EquiSeal provide rapid viscosity increase during injection, allowing precise placement of the system in the targeted area. EquiSeal service is applicable to different completion types—openhole, stand-alone screen, open- and cased-hole gravel pack, and others. Halliburton conformance portfolio can help operators maximize the efficiency and recovery of their assets.

Advanced sealant technology 

EquiSeal conformance sealant is based on a proven polymer gel system combined with proprietary rheological modifiers. EquiSeal and EquiSeal NWB sealants use an organically crosslinked polymer system that provides unprecedented sealant capabilities for controlling unwanted fluid production.

Advantages

  • Allows precise placement of the gel system in the targeted area due to its stress-dependent rheological properties
  • Applicable in a wide range of temperatures, from 140°F (60°C) to 250°F (121°C)
  • Resistant to H₂S, CO₂, and acid environments
  • Provides a predictable, controllable crosslinking reaction time from liquid to gel state for optimal placement
  • Can be tailored for deep penetration into the formation or to bridge off at the formation face

As with all our conformance services, EquiSeal services are backed by Halliburton reservoir-focused engineering and technology.
