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, which means additives are significantly reduced or cut altogether. It means that our fluids are truly multi-functional, providing 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.

Our unique cesium formate brine has been trusted by leading oil and gas operators for challenging drilling, completion, workover and intervention operations for over twenty years.

Assured supply of cesium formate

We own and operate the Tanco mine in Manitoba, Canada. Here we extract pollucite ore, the base for cesium formate fluids. The Tanco mine contains the majority of the known global reserves of this rare mineral, so we are assured of stock for decades to come. Furthermore, as part of Sinomine, we have access to additional reserves and mining expertise to complement our own resources.
