Barite Products

The company produces high quality drilling grade barite either ground or in lump presentation according to client’s specifications.

Barite (Barium Sulphate BaSO4) is a heavy and inert mineral. 100% pure Barite has a specific gravity (SG) of 4.5 and 95% of its use is as a weighting and lubrication agent in oil & gas well drilling fluids (also called drilling mud). In drilling fluids, the specific gravity specifications range from 4.1 SG to 4.25 SG.

The drilling fluid purpose is to: 

        Clean cuttings from the well bottom.
        Flush those cuttings to the surface.
        Cool and lubricate the drill bit.
        Deposit a “ filter cake’ layer on the wellbore wall to prevent loss of the circulating fluid.
        Prevent formation fluids entering the borehole and mixing with circulating fluids.
        Support the walls of the well bore without damaging the formation.
        Control pressures under the surface.

Barite is used over other industrial minerals in the drilling process not only because of its weight (there are many other materials that are heavier) but because the mineral is chemically inert or its molecular structure very stable. What this means is that when submitted to high pressures and temperatures down in the drilling hole, it doesn’t create a chemical reaction. Some of its other properties are that it is practically insoluble under ordinary conditions in all the usual chemical reagents, has as a strong inertia, good stability, low oil absorption, easy wettability, low abrasiveness, acid and alkali proof, moderate rigidity and high specific gravity. In the drilling mud it suppresses high formation pressures and prevents blowouts. An additional benefit of barite is that it does not interfere with magnetic measurements taken in the borehole, either during logging-while-drilling or in separate drill hole logging. Usually, the deeper and more complex the well is, the more barite is needed as a percentage of the total mud mix.
