Micronized weight material optimizes ERD drilling Offshore

Feb 01, 2008  However, extensive research and field experience has shown that reducing particle diameter by 100 reduces settling, or sag, by a factor of 10,000. With this development, barite is ground from an average of 75 to less than 5 um, with an average size of 1 to 3 um, or about one-eighth the size of a human blood cell.
