FlexSEAL advanced flexible expanding cement helps ensure well integrity by resisting stresses encountered throughout the well life cycle.

Unlike conventional cement systems, FlexSEAL cement expands after setting, improving cement bonding and blocking hydrocarbon migration. Designed with a low Young’s modulus, the cement absorbs cement sheath stresses without cracking, reducing the risk of

• annular pressure buildup 
• sustained casing pressure (SCP)
• mechanical well damage 
• cement sheath failure 
• casing collapse
• tensile cracks 
• cement debonding 
• costly remedial cementing jobs.

Resist stress, gas migration, fluid losses, and corrosion

FlexSEAL cement incorporates particle-size-distribution technology to extend density, pressure, and flexibility limits. It can be used in wells with temperatures ranging from 40 to 482 degF [4.4 to 250 degC].

During placement, the FlexSEAL cement's optimized slurry viscosity and solids volume fraction provide effective mud removal and fluid loss control. After placement, the cement provides low gel strength, short transition time, and high compressive strength.
