High-Grade Silica 99.7% SiO2

Silica Flour

Throughout the Western Canadian Sedimentary Basin, wellbore temperatures can exceed 110°C due to well depth or physical treatment. In these environments, silica flour is required as an additive to standard cement (Oilwell Class G) to ensure permeability and compressive strength requirements are met.

Northern Silica Corporation’s Mount Moberly White™ SF 325 has a SiO2 count of > 99.5% with 85% passing 325 mesh, meeting industry size and quality specifications for use as a silica flour in oil & gas well cementing.
