Details:
Sodium acid pyrophosphate (SAPP) is white powder or granular phosphate based product which is effective in treating cement-contaminated muds. SAPP is a calcium scavenger that used to treat calcium concentration from cement in water-based fluids. SAPP is a strong mud thinner (deflocculant) in fresh water fluid systems. The main application is mud rings dispersion during water drilling process and as a rapid thinner prior to cementing casing. SAPP is effective in reducing bit-balling by dispersing native clays at the bit. It can control free calcium in low pH drilling mud systems, where bicarbonate soda and high pH soda ash cannot be utilized. Sodium acid pyrophosphate is effective at low concentration levels which can be used as a low-cost, fast-acting dispersant in low-weight freshwater drilling mud systems. 
Advantage: 
 ♦Effective mud thinner with low cost
 ♦Treat out Cement Contamination 
 ♦Prevent Drilling Bit Balling 
Technical Data:
sodium acid pyrophosphate SAPP drilling fluid spec
Recommended dosage 
SAPP reduces the pH range of drilling fluid and is normally not used in fluids with pH >=9.5.
In water well drilling applications normally add 12-24 Kg/m3 SAPP. Jet and surge this solution through the screen and gravel pack. Do not add dry SAPP dispersant directly into the well, screen or gravel pack.
For thinning of drilling fluid, Add 0.5 - 1 kg/m3 into drilling fluid. Completely dissolve SAPP in a chemical barrel with a small quantity of water, then add it slowly to the circulating mud system.
