Sodium Silicate is the common name for a compound sodium metasilicate, Na2SiO3, also known as water glass or liquid glass. It is available in aqueous solution and in solid form and is used in cements, passive fire protection, refractories, textile and lumber processing, and automobiles. Sodium carbonate and silicon dioxide react when molten to form Sodium Silicate and carbon dioxide.
Sodium Silicate Liquid Drilling additive is water soluble Sodium Silicate used for Wellbore Stabilization in the Oilfield Industry.
For drilling fluid uses, Sodium Silicate, also known as waterglass, is frequently used in drilling fluids to stabilize borehole wells and to avoid the collapse of bore walls. It is particularly useful when drill holes pass through argillaceous formations containing swelling clay minerals such as smectite or montmorillonite.
Sodium Silicate provides inhibition and well-bore stabilization when drilling highly reactive shale formations using water-based fluid systems.
Application Sodium Silicate provides enhanced inhibition and well-bore stabilization while drilling highly reactive shale formations using fresh and salt water drilling fluid systems.
Technical and Engineering Information Sodium Silicate contains simple and complex silicate structures that physically and chemically stabilize reactive shales through two mechanisms: gelation and precipitation.
