Mercury sometimes is present at elevated concentrations in US, Canadian, and North Sea drilling muds; it is derived from mercury contamination of drilling mud barite (Neff, 2002b). Impure grades of barite also may contain elevated (compared to natural sediments) concentrations of all the other metals listed in
2 #0183;#32;Drilling muds are traditionally based on water, either fresh water, seawater, naturally occurring brines, or prepared brines. Many muds are oilbased, using direct products of petroleum refining such as diesel oil or mineral oil as the fluid matrix. In addition, various socalled syntheticbased muds are prepared using highly refined fluid compounds that are made to moreexacting property
Drilling Industry: The overwhelming majority of the barite that is mined is used by the petroleum industry as a weighting material in the formulation of drilling mud. Barite increases the hydrostatic pressure of the drilling mud allowing it to compensate for highpressure zones experienced during drilling.
Barite is mostly used in oil well drilling fluids as it tends to surge the density of these liquids. Being a heavy weighing agent, it is used as an additive to the waterbased drilling mud fluid which helps in increasing the density as per the requirement.
BaSO4 (Baryte or Barite) mineral barium sulfate is generally white. Barite usually serves as a weighting agent in drilling muds for HDD and drilling fluids in oil and gas exploration. Product density avoids highpressure blowouts (nonmagnetic). Product with a specific gravity
Common Challenges Relative to the Use of Decanter Centrifuges for Barite Recovery in the Oil amp; Gas Industry When centrifuges are properly deployed, they can have dramatic effects on drilling performance. In fact, without them, many of the advances made in drilling would not have been considered achievable.
The American Petroleum Institute (API) has established specifications for the use of barite in drilling mud. To meet these specifications, the barite is finely ground so that at least 97% of the material, by weight, can pass through a 200mesh (75m) screen, and no more than 30%, by weight, can be less than 6 m diameter.
Pure barium sulfate has a specific gravity of g/cm 3, but drillinggrade barite is expected to have a specific gravity of at least g/cm 3 to meet API specifications. Contaminants in barite, such as cement, siderite, pyrrhotite, gypsum, and anhydrite, can cause problems in certain mud systems and should be evaluated in any quality assurance program for drilling mud additives.

Barite for Oil Drilling Mud. These highdensity muds are pumped down the drill stem, exit through the cutting bit and return to the surface between the drill stem and the wall of the well. This flow of fluid does two things: it cools the drill bit. the highdensity barite mud suspends the rock cuttings produced by the drill and carries them up
