Bentonite API-9 is natural sodium bentonite specially designed for the production of fluids for oil and water drilling and Bentonite API-9 is a high quality product and its characteristics meet API SPEC 13A Section 9 (Eighteenth Edition Aug 2010) specifications for bentonite.
Properties of Bentonite API-9 (Bentonite)
Viscometer dial reading at 600 rpm
Yield Point / Plastic Viscosity Ratio
Max. 15 Cm3
Residue greater than 75 µm (200 Mesh)
Application : –
Bentonite API-9 is used for viscosity and filtration control in fresh water mud systems.
Bentonite API-9 is used in drilling fluids to lubricate and cool the cutting tools, to remove cuttings, and to help prevent blowouts.
Bentonite API-9 is a cost effective means of achieving viscosity, fluid loss control and filter-cake quality in freshwater and seawater muds.
As with all bentonite products, the yield decreases as the salinity increases. In muds with salinity of 3500 mg/L or higher the bentonite API-9 must first be pre-hydrated in fresh water, before adding it to the mud system.
