Advantage :

regarded as a secondary sulfide scavengerWhen Hematite is used in H2S areas, a high pH should be maintained and an appropriate primary scavenger, should be used.

• Muds contain fewer solids than similar-density barite muds due to the 20% higher specific gravity
• Muds have improved rheological values; generally plastic viscosities are 2 to 30% less than barite muds.
• Use of muds usually results in higher rates of penetration.
• Higher bulk density than barite, consequently more weight is held in the same volume bulk tanks and a smaller volume must be
transported to the wellsite.
• Less Hematitethan barite isrequired to achieve the same mud weight, reducing mud costs.
• Has a narrower particle size distri-bution with a larger average particle size as compared to barite.
• A harder mineral than barite, thus more resistant to particle-size degradation.
• Approximately 97% acid-soluble in 15% hydrochloric acid (HCl).Will partially scavenge hydrogensulfide at neutral and low pH levels and
• May be environmentally preferred to barite in certain locations
