Used primarily in high-performance drilling and completion fluids in the oil and gas industry. Its high density and low viscosity make it ideal for maintaining wellbore stability in deep and high-pressure wells. It is especially valuable in horizontal and extended-reach drilling due to its ability to minimize formation damage and provide excellent shale inhibition. The monohydrate form enhances thermal stability, allowing use in elevated temperature environments. It is also compatible with various other fluid components, reducing corrosion risks and enabling efficient fluid recovery and re-use. Additionally, it is considered more environmentally acceptable compared to other heavy brines, supporting safer disposal and reduced ecological impact.
