This innovative technology eliminates up to 85% of embodied CO 2 emissions compared with conventional well cementing systems, which include portland cement. The cement-free EcoShield system is a breakthrough that delivers industry-standard zonal isolation capabilities while significantly minimizing impact from upstream oil and gas production.

Recycled tire waste is already used as a component of Portland cement, but graphene has been proven to strengthen cementitious materials, concrete among them, at the molecular level. After useful oils are extracted from waste tires, this carbon residue has until now had near-zero value, Tour said. —James Tour. After 28 days, 0.1
