Barite

1. 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

Appearance : Fine, beige coloured powder

PH in water : Neutral

Specific gravity, g/cm3 : > 4.2

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)
