Abstract
Millions of abandoned oil and gas wells leak methane and harmful chemicals, threatening groundwater, fueling climate change, and creating regulatory headaches. Traditional cement plugs crack, shrink, and fail. Alternatives like bismuth and resin are pricey, tricky, and unreliable.
Benefit
A breakthrough cement composite plug engineered for ultra-durability and near-zero permeability.
•4× stronger than standard mortar (150 Mpa compressive strength).
•10,000× lower permeability than conventional cement-locks methane in.
•Shrinkage- and crack-resistant microstructure for long-term stability.
•Bonds tightly to steel casings under harsh conditions.
•Cost-effective, applied with standard industry methods.
Market Application
•Plugging abandoned oil & gas wells
•Geothermal & carbon capture well sealing
•Offshore & onshore decommissioning
