Reduced Portland Cement Systems - Data Sheet

As we transition to a lower-carbon future, it is critical to design dependable cement barriers with reduced Portland content. To meet this challenge, Halliburton has developed a portfolio of reduced Portland cement systems that includes NeoCem™ cement, NeoCem™ E+ cement, and EnviraCem™ cement. These cement systems contain less mass of Portland content compared to conventional designs. The reduction in Portland content helps customers lower their carbon emissions baseline and provides engineered cement systems with enhanced cement sheath performance. NeoCem Cement System: average 40% reduction in mass Portland cement of blend NeoCem E+ Cement System: 50%-70% reduction in mass Portland cement of blend EnviraCem Cement System: greater than a 70% reduction in mass Portland cement of blend Reduced Portland, High-Performance Cement Systems NEOCEM™ CEMENT, NEOCEM™ E+ CEMENT, AND ENVIRACEM™ CEMENT • Lower Portland content compared to conventional cement systems • Leverages more mined and recycled materials • Enables higher compressive strength at a lower density • Increased ductility • Reduced permeability • Enhanced sheath performance • Delivered using same equipment and processes as conventional designs FEATURES CEMENTING | Cement Systems OVERVIEW • Contributes to a lower carbon footprint per cement job • Reduces supply chain constraints • Reduces ECDs to achieve planned top of cement • Improved resistance to cyclic loading and wellbore stresses • Improved corrosion resistance • Improved wellbore isolation to reduce fugitive emissions • Operationally efficient BENEFITS
