Novel hybrid cement formulation improves strength and carbon footprint in oil well applications, indicating a sustainable innovation.

The aim is to develop a hybrid cement for high-temperature oil well applications that enhances performance and sustainability.
Prepared cement slurries with various compositions according to API specifications.
Cured slurries at high temperature (80 °C) for 28 days.
Conducted evaluations for rheology, fluid loss, mechanical strength, and microstructural analysis.
Achieved 46.7% reduction in fluid loss compared to plain OPC.
Demonstrated 33.4% increase in compressive strength.
Showed 129.1% improvement in shear bond strength over neat OPC.
Reduced carbon emissions by approximately 135 kg CO₂ per ton through clinker replacement.
