Optimize slurry performance and mechanical integrity

CemCRETE concrete-based oilwell cementing technology increases the solids content of the slurry using particle-size distribution. Smaller particles fill the void between larger particles, requiring less water. This results in a cement slurry with improved flow properties and excellent set properties, such as permeability and strength. A lower water-to-cement ratio during mixing and pumping enables higher long-term performance.

CemCRETE technology offers

  • more solids in your cement
  • greater compressive strength
  • reduced cement permeability
  • greater resistance to corrosive fluids.
Standard cement slurries require water to fill the void between particles. CemCRETE slurries fill the interparticle void with more solids, giving superior cement properties.
