IntegraBond™ HEAL

A self-healing cement system for a superior cement annular seal

IntegraBond™ HEAL is a self-sealing cement system that provides a durable cement sheath, ensuring well integrity and zonal isolation for the life of the well. Because of changes in pressure and temperature to the cement sheath over time, the cement sheath may fail or crack and allow annular pressure to build up. This cracking and pressure build-up can result in: 

  • Sustained casing pressure
  • Cross flow
  • Lost production
  • Collapsed casing
  • Contaminated water zones
  • Increased workover costs

By incorporating IntegraBond HEAL additive into the cement blend, this solution improves the mechanical properties of the cement. If the cement cracks and is infiltrated by hydrocarbons, upon contact, the self-sealing material absorbs the hydrocarbon and swells the material to plug the gap and shut off and seal the hydrocarbon flow. The additive remains inactive in the set cement until hydrocarbon contacts the material. 

Results show that cracks up to 0.009 in. (0.2286 mm) can be effectively sealed. It can self-seal multiple times and delivers a durable cement sheath in a wide variety of field conditions.
