Designed to create an expanding wellbore sheath
With Tuned Cementing Solutions™ cementing systems, Halliburton has created a set of innovative fit-for-purpose solutions with the flexibility required to allow each system to be tuned specifically for a given set of wellbore conditions. ExpandaSeal cements form one of these families of fit-for-purpose solutions.
With ExpandaSeal cement you receive a foamed cementing solution designed to create an expanding wellbore sheath. Expanding set cements may solve problems associated with initial micro-annular. ExpandaSeal cements can provide the additional benefits of increased compressibility, bridging, and elasticity gained through the introduction of stable, well-dispersed small N2 bubbles at higher densities.
