barite - Schlumberger Oilfield Glossary

A dense mineral comprising barium sulfate [BaSO 4].Commonly used as a weighting agent for all types of drilling fluids, barites are mined in many areas worldwide and shipped as ore to grinding plants in strategic locations, where API specifies grinding to a particle size of 3 to74 microns. Pure barium sulfate has a specific gravity of 4.50 g/cm 3, but drilling-grade barite is expected to have ...

A New Process For Sulfate Removal From Industrial Waters

This process is a true reduction of total dissolved solids (TDS) in that all chemicals added for treatment are precipitated during the reactions. Operating costs for near-complete sulfate removal using the process, which has been demonstrated successfully for many industrial waters, are estimated at $3 to $6 per 1000 gallons treated.
