CALCIUM NITRATE
CALCIUM NITRATE is a hydrated salt and used as a calcium source in clear water drilling, invert emulsion muds and as an accelerator in cementing. CALCIUM NITRATE is also a source of nitrates which can be used to revitalize well sites and other project locations. Nitrogen-loading limits as described in the ERCB D-50 should be followed.
Application
CALCIUM NITRATE is used in clear water drilling, invert emulsion muds, cementing and dewatering as a calcium source. In the dewatering process CALCIUM NITRATE is used as a coagulant to neutralize the charged particles on the suspended solids.
Advantages
- Excellent source of calcium
- Can be used to revitalize well and project sites (fertilizer)
- Effective coagulant
