CALCIUM NITRATE, also known as ENVIROFLOC, is the hydrated double salt: 5Ca (NO3)2•NH4NO3•10H2O. It is used as a calcium source in clear water drilling, invert emulsion muds and as an accelerator in cementing.
• An excellent source of calcium
• In moderate quantities, nitrates are a plant nutrient, aiding in the re-vegetation of well
sites. (Be aware of ERCB D-050 nitrogen-loading limits)
1-3 kg/m³ (or as required) to maintain 200-400 mg/L of calcium ion for clear water drilling.
