Features
EcoShield low-carbon geopolymer cement-free system minimizes carbon footprint during well construction.
Well construction includes hard-to-abate emissions, notably from well cementing operations. Reducing these emissions is a priority because cement is used in nearly every well drilled today, with an impact of approximately one metric ton of carbon emissions per metric ton of cement used. The EcoShield™ low-carbon geopolymer cement-free system addresses the environmental impact of well construction, eliminating up to 85% of embodied CO2 emissions compared with conventional well
cementing systems.
How it improves performance
Our EcoShield low-carbon system provides a more sustainable alternative to portland cement while delivering comparable performance and long-term zonal isolation.
How it works
The EcoShield low-carbon system matches the rheology, thickening time, and compressive strength properties of conventional portland cement-based systems. The system ts within standard oil eld cementing work ows without major changes to the design process, onsite execution, or postjob evaluation.

Emissions reduction: Proven to eliminate up to 85% of embodied CO2 emissions compared with
conventional well cementing systems
Onshore cementing operations O shore cementing operations
Delivers industry-standard wellbore zonal isolation capabilities while minimizing environmental impact Drives down Scope 3 carbon dioxide emissions by using geopolymers composed with locally sourced natural materials and industrial waste streams Provides an alternative to conventional well cementing systems, which include manufactured portland cement, helping to ensure business continuity in cement supply-constrained markets and avoid nonproductive time
Geopolymers are made from aluminosilicate, a more robust and durable material considered a more sustainable alternative to portland cement System ts within standard oil eld cementing work ows without major changes needed to the design process, onsite execution, or postjob evaluation Cement-free formula is customizable to meet speci c well properties, o ering readily tunable slurries and set properties Compatibility with other wellbore uids, including spacers and drilling uids, is ensured Conventional logging tools can be used to evaluate the performance of the set geopolymer downhole
