DESCRIPTION
Barite is a high purity barite(Barium
Sulfate) with the formula, BaSO4. It is efectively used to increase
the density of all types of drilling fluids.
2.
APPLICATION
Barite is used in all drilling fluids for
the purpose of increasing density, because its high density.
3.
TYPICAL PROPERTIES

4.
RECOMMENDED TREATMENT
The amount of Barite needed to increase mud
density is calculated as below:
WB: Metric
tons(1000 kg) of Barite
W1: Initial mud weight(g/cm3)
W2: Desired mud weight(g/cm3)
V1: Initial volume of mud(m3)
