2019-11-13 ilmenite were first ground to near API barite particle sizes and the abrasion compared to API-grade barite. Both hematite and ilmenite had a much greater abrasion value than barite at the API grind size. Then the alternative weight materials were micronized to a finer particle size as shown in Figure 4 and evaluated in the same manner.

Hematite Tdss It is weight material is a high-quality, ground iron oxide (hematite) with a Specific Gravity (SG) of above 5. Due to this high specific gravity, muds formulated with hematite have lower solids contents and frequently contribute to higher rates of penetration as compared to barite muds.
