T he IsoBond cement system alleviates SCP on all fronts , unlike slurries that are only designed to mitigate against fluid loss . With rapid gel strength development and short slurry transition time, Iso B ond lessens annular flow through cement and increases the anchoring force to the casing and formation by up to 40% when compared to traditional systems . This improved shear bonding results in a cement sheath that is more resistant to degradation from corrosive fluids. The Iso B ond cement system ’ s transition time to prevent gas migration are greatly reduced and the cement’s permeability can be reduced up to 75% compared to other cement systems. “ By utilizing IsoBond to proactively mitigate SCP, our customers minimize risk, reduce cost, and limit t heir carbon footprint by eliminating the need for future remediation , ” sa id J im Collins, v ice p resident of Cementing . IsoBond is a dry blended cement system that provides significant operational efficiencies for land operations over liquid additives, while delivering comparable benefits. Utilizing the IsoBond cement system achieve s a more efficient, sustainable, and economical cement solution that successfully manage s gas migration and annular flow. Halliburton has pumped over 15,000 barrels of Iso B ond across multiple wells in North America and Latin America. The IsoBond cement system will be available globally by the end of 2021.
