Sodium Formate

• Formate drilling and completion fluid systems are more environmentally friendly than chloride and bromide salts, with low toxic solid content, easy solubility in water, and strong shear thinning ability, which is conducive to rapid drilling. It can form a thin mud cake, resulting in a regular wellbore, which is beneficial for logging and improving cementing quality. The filtrate has good compatibility with formation fluids, which is conducive to the discovery and protection of oil and gas reservoirs. It has strong anti-pollution ability, stable performance, and simple maintenance. It has good inhibition and anti-collapse capabilities.

Formulated for solid-free completion fluids and workover fluids with densities up to 1.32 g/cm³, this fluid is designed for reservoir-specific drilling fluid systems and formate-based drilling and completion fluid systems. It is widely used in small-borehole drilling, horizontal wells, deviated wells, and environmentally sensitive drilling areas.
