EcoShield

Corrosion-resistant geopolymer cement-free system

Maintain wellbore integrity and prevent casing corrosion with geopolymer cement-free system

Applications

Benefits

Features

EcoShield corrosion-resistant system is a sustainable portland cement-free alternative for oil and gas well cementing.

Geopolymers are unique amorphous materials made from aluminosilicate, which makes them more durable in highly corrosive environments. A comprehensive lab evaluation of the EcoShield™ corrosion-resistant geopolymer cement-free system at bottomhole conditions proved that its use for primary cementing in highly corrosive environments is more e ective and durable than conventional well barrier solutions.

How it improves performance

Our EcoShield corrosion-resistant system provides better durability in comparison with conventional well cementing systems in corrosive downhole environments.

How it works

The system o ers corrosion resistance while matching the rheology, thickening time, and compressive strength as conventional Portland cement-based systems.
