    BAROID® 41

    BAROID® 41 weighting material is a specially processed barite in powder form for use as a drilling fluid weighting additive. BAROID 41 weighting material has a specific gravity of 4.1 and can be used to increase the density of drilling fluids up to 21 lb/gal (2.40 sg).


    Helps increase drilling fluid density up to 21 lbs/gal (2.4 sg). Helps control formation pressures. Helps stabilize the borehole.


    High quality, free from corrosive and abrasive material. Chemically inert. Cost-effective weighting agent.

    Recommended Treatments

    • Before adding BAROID® 41 weighting material, the Marsh Funnel viscosity (sec/qt) of the circulating fluid should be increased to four times the desired final weight by the addition of AQUAGEL® or QUIK-GEL® additives
    • Add BAROID® 41 material through a high shear mixer so the entire circulating volume is at uniform weight
    • To control an artesian flow at the surface, premix the necessary volume of weighted mud and apply in one continuous operation

    NOTE: In near surface holes drilled in unconsolidated alluvium (overburden), weights in excess of 11 lbs/gal (1.32 sg) could result in loss of circulation.

    The above are generalized concentrations of BAROID® 41 weighting material to be added to fresh-water based drilling fluids. The ultimate usage concentration will be based on subsurface pressures encountered, application and mixing efficiency. In the event that further information is needed, please refer to the Product Data Sheet or contact your local Baroid IDP representative.
