Oil and drilling

Our sodium silicates are used in silicate-based drilling fluids, which are an effective, versatile and low cost alternative to oil-based drilling fluids. Our products are known for providing superior well bore stability.

Our sodium metasilicates are very performant in normal and heavyweight slurries for reducing the mobility of water. They are widely used as a cost effective extender, allowing a higher ratio of water to cement. They can also be used as a cement accelator.

Principal Benefits

Tailor made products

Our liquid silicates can be adjusted regarding SiO2/Na2O ratio and solid content to meet the needs of your formulation. Our sodium silicate granules are available in different ratio's and can be grinded towards the particle size needed to obtain the reaction speed you are looking for. 

In our well equipped mixing division we are able to prepare your own tailor-made sodium silicate based drilling fluids.

Easy and safe to handle

Our sodium silicates are non-toxic and are odor free. Furthermore our products are wholly inorganic and therefore not flammable and once diluted they have no environmental impact.

When conditions request, such as limited storage capacity or danger towards freezing temperatures, our granulated silicates can offer you a cost effective alternative to liquid silicates.
