Place of Origin: IN; Model Number: Oil well drilling bentonite; Oil well drilling bentonite: Oil well drilling Bentonites
Specifications for Drilling/Pilling grade of Bentonite powder. Viscosity: (Dial 600 reading.): 40 min. ph: 9 min. Bulk Density: 1.2 Kg/cm3 max. Liquid Limit: 500 min. Moisture/ Water Content: 12%max. Dry Screen Analysis: Pass through 100 mesh sieve 99% min.
Pass through 200 mesh sieve 85% min.
OCMA Grade Bentonite Viscometer Dial Reading at 600rpm: 30 Min. Yield point / Plastic viscosity ratio: 6.0 Max. Fluid Loss: 16.0 ML. Residue Greater than 75 Micro: 2.5 Wt. % Max. Moisture: 12.0% Max.
Drilling grade bentonite powder: Is a balanced powder to give optimum result in oil well, tube well drilling, pilling and grouting. This type of bentonite has high gelling and swelling capacity. Small percentage of this grade gives very viscose slurry and very good fluid loss control.
Yield: The yield of 15 cPs apparent viscosity. Bentonite and distilled water slurry mixed after 24hour shall be not less than 90 lbs per short ton (200lbs) of bentonite.
Fluid loss: The API fluid loss of slurry containing 71gms of bentonite in 100mgs distilled water mixed and aged 24hours shall not be greater than 25 mls.
Moisture content: The moisture of the bentonite shall not greater than 2.5% by weight.
Dry screen analysis: The amount passing through U.S. standard sieve No. 100 shall be at least 98 %
Sand content: The sand content of the bentonite shall not be greater than 2.5% by weight.
