SLB INTRODUCES LOW-CARBON ALTERNATIVE FOR WELL CONSTRUCTION CEMENT

SLB has introduced the EcoShield™ geopolymer cement-free system that minimizes the CO2 footprint of a well’s construction. This innovative technology eliminates up to 85 percent of embodied CO2 emissions compared with conventional well cementing systems, which include portland cement. The EcoShield system has the potential to avoid up to 5 million metric tons of CO2 emissions annually—the equivalent of removing 1.1 million cars from the road each year.

In addition to its embodied CO2 emissions, portland cement creates significant transportation-related emissions from manufacture to deployment. The EcoShield system uses locally sourced natural materials and industrial waste streams in its composition, making this a far more sustainable well integrity method.

The cement-free system can be deployed throughout various phases of the well life cycle including abandonment. It can also be deployed across a range of field applications, including corrosive environments.
