Reduced Portland content helps customers lower carbon emission baselines and provides engineered systems with enhanced barrier performance
Talk to an expertIn oil well cementing, Portland cement accounts for approximately 99% of the mass of the slurry design and the majority of the carbon footprint due to the CO2 that is released during the manufacturing process. As we transition to a lower-carbon future, it is critical that dependable barriers are designed with reduced Portland content. To meet this challenge, Halliburton has developed a portfolio of reduced Portland slurries that includes the NeoCem™ system, NeoCem™ E+ system, and EnviraCem™ system. These reduced Portland blends contain less mass of Portland content compared to conventional designs. Reduced Portland content helps customers lower carbon emission baselines and provides engineered systems with enhanced barrier performance.
Up to 50% reduction in mass Portland cement of blend.
50%-70% reduction in mass Portland cement of blend.
70% or greater reduction in mass Portland cement of blend.
NeoCem, NeoCem E+, and EnviraCem systems leverage the synergies between the chemical and physical properties of specialized materials combined with Portland cement. Halliburton’s innovative tailoring process engineers these reduced Portland systems to deliver high-performance, compressive strength and ductility, at a lower density than conventional systems for improved barrier dependability.
Reduced Portland Systems
Our reduced Portland systems can better withstand the downhole demands from continual pressure and temperature changes throughout the life of the well to provide improved long-term zonal isolation compared to conventional cement systems.
Reduced Portland Systems
A cement sheath with low permeability provides more resistance to corrosive fluids and gases downhole to deliver a dependable barrier for the life of the well. Permeability testing of the four different density EnviraCem systems resulted in ranges from 0.01 to 0.42 µD. This range is exponentially lower than 0.1 mD or gas tight permeability.
