Hematite is a mineral consisting of iron oxide. It has a deep red to gray-black color and a metallic luster. It is widely used as a pigment, jewellery material, and in various industrial applications.

Hematite powder is used in oilfield drilling operations for the following applications:

  • Weighting Agent: Hematite powder is often used as a weighting agent due to its high specific gravity.
  • Density Control: Drilling fluid needs to be precisely controlled to balance pressure from surrounding formations.
  • Rheological Properties: Can affect the rheological properties of the drilling fluid, including viscosity and gel strength.
  • Bridging Agent: Can act as a bridging agent in drilling fluids. It helps to form a filter cake on the wellbore wall.
  • Lubrication and Cooling: During drilling, the drilling fluid serves as a lubricant and coolant for the drill bit.

It is an important additive that contributes to safe and effective drilling processes.
