Sodium Chloride (NaCl) is a widely available commercial chemical that can be used as a weighting agent to increase fluid density up to 1.2sg (10lb / gal). It is predominately used for formulating clear, solid free work-over and completion fluids. Sodium chloride can also provide inhibition to formations containing water sensitive clays and shales.
SODIUM SULPHITE helps effectively scavenge soluble oxygen from water-based drilling fluid systems. SODIUM SULPHITE also helps extend the life of organic polymers by eliminating conditions that promote their thermal degradation.
STONEDUST is sized calcium carbonate that is effective in bridging, weighting, controlling seepage and circulation losses in drilling, drill-in, and completion fluids.
