IntegraBond™ FLEX

Durable cement for high-stress applications

IntegraBond FLEX cement systems use a special selection of mechanical property enhancers to improve the flexural and tensile strength, elastic properties and fracture toughness of the set cement. 

Cement failure can be caused by exposure to forces which exceed its mechanical strength and can be induced from excessive wellbore pressure, temperature cycles or formation depletion. These changes occur during completion, production or remediation activities including hydraulic fracturing and water, gas or steam injection. Failure of this seal may result in production of undesirable water or gas, or gas to surface, usually manifested by sustained casing pressure (SCP). 

IntegraBond FLEX cements are designed using proprietary software and tested with a variety of specialty laboratory protocols to ensure fit-for-purpose mechanical properties.
