FUTUR Self-Healing Cement System

Achieve long-term zonal isolation and well integrity

Cement sheath damage can occur during drilling, perforation and stimulation, and subsequent production—and even after abandonment. The damage significantly compromises well integrity, resulting in sustained casing pressure, surface casing vent flow, or hydrocarbon crossflow. To respond to cement sheath damage or loss of hydraulic seal, the FUTUR self-healing cement system works within the cement after it has already set.

Where conventional slurry designs and gas migration prevention tools are effective only during cement placement, FUTUR cement self-heals from the time it is placed until the end of the well’s operational life and into abandonment. It reacts to close flow paths so that within hours, cracks are repaired and the cement sheath is restored without the need for well intervention. The self-healing properties of this cement provide a durable cement sheath, long-term zonal isolation, and reliable cement sheath repair to preserve well integrity.

Long-term well integrity in Canada

Drilling for heavy oil in the Central Alberta Foothills, Suncor Energy encountered shallow gas formations, where cement sheath damage caused gas to migrate to surface. The damage resulted in surface casing vent flows and sustained casing pressure. The company used FUTUR self-healing cement with standard equipment and procedures. Well integrity was restored, and more than 3 years after implementation, wells showed no sign of pressure buildup in the annulus or at surface. Read case study

Critical zonal isolation in Germany

Berliner Gaswerke AG operates an underground gas storage facility in the highly populated city of Berlin. Effective zonal isolation is critical to ensure the facility’s efficiency and environmental protection. The company needed to drill and complete a leak-free well and chose a strategy including FUTUR self-healing cement. The cement provided a barrier against leaks that continued to reseal whenever annular integrity was compromised.

After cement placement, ultrasonic logs confirmed optimal cement bonding across the treated interval. No surface leaks were detected, and because no remedial cementing job was required, the operator saved 3 days of rig time.
