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 under extreme pressure and temperature conditions. It is non-damaging to production zones, making it suitable for use in open-hole completions. Also serves as a formate source in specialty chemical synthesis and has applications in certain types of heat transfer systems due to its thermal stability. Its clear brine formulation allows for better downhole visibility during operations.
