Engineered systems with enhanced performance

In 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.

NeoCem™ System

Up to 50% reduction in mass Portland cement of blend.

NeoCem™ E+ System

50%-70% reduction in mass Portland cement of blend.

EnviraCem™ System

70% or greater reduction in mass Portland cement of blend.

Reduced Portland Cement Systems

Lower density, higher compressive strength

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

Increased ductility

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

Reduced permeability

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. 

Tailoring methodology provides flexibility for utilization of locally sourced materials

Our innovative approach to design reduced Portland systems incorporates more locally sourced, natural, and recycled materials. The reduced dependence on Portland cement to provide a dependable barrier enables flexibility with industry supply chain challenges and delivers a more sustainable barrier solution.
