Our philosophy

We believe in ‘performance through simplicity’. We don’t like to over-complicate matters, which is good, because we don’t need to. Cesium formate is unique. No other base brine has such a mix of operation-enhancing qualities, resulting in a significant reduction or complete elimination of additives. It means that our fluids are truly multi-functional. They provide operators with the flexibility to drill and complete in exactly the same fluid, or to use cesium formate for a wide range of other applications. Learn more about cesium formate’s properties and applications by downloading our brochures and Formate Technical Manual.

Leading oil and gas operators have trusted our unique cesium formate brine for over twenty years in challenging drilling, completion, workover, and intervention operations.

Assured supply of cesium formate

We own and operate the Tanco mine in Manitoba, Canada, where we extract pollucite ore, the base for cesium formate fluids. Since our Tanco mine holds the majority of the world’s known reserves of this rare mineral, we can rely on a steady stock for decades. Additionally, as part of Sinomine, we access additional reserves and mining expertise to strengthen our resources.
