Barite weighting agent which is also use an additive in drilling mud
Barite is a mineral composed of barium sulfate. The high specific usages is so wide like industrial, medical, and manufacturing uses. Barite also serves as the principal ore of barium. It is especially common as concretions and vein fillings.It occurs among where these carbonate rock units have been heavily weathered, large accumulations of barite are sometimes found at the soil-bedrock contact. It is also found as concretions in sand. These concretions grow as barite crystallizes within the interstitial spaces between sand grains
Uses of Barite
Most barite uses as a weighting agent in muds. These high-density muds are pumped down the drill stem, exit through the cutting bit and return to the surface between the stem and the wall of the well. This flow of fluid does two things: 1) it cools the drill bit; and, 2) the high-density barite mud suspends the rock cuttings produced by the drill and carries them up to the surface.
It also uses in painting, paper, cloth and rubber. When it uses in paper because of weighting properties it converts paper to card or something more rigid. It is also used in a wide variety of other applications including plastics, clutch pads, rubber mud flaps, mold release compounds, radiation shielding, television and computer monitors, sound-deadening material in automobiles, traffic cones, brake linings, paint and golf ball
There it is used as a weighting agent in mud. This is a growth industry, as global demand for oil and natural gas has been on a long-term increase. In addition, the long-term drilling trend is more feet of drilling per barrel of oil produced.It prices is low none of other substitutes have been effective at displacing barite in any major market area. They are too expensive or do not perform competitively.
Barite in drilling
It has crucial importance in drilling likes stabilizing the well hole without damaging , keeping formation fluids at bay , clear cutting from clays and finally having weighting properties It gives some properties to mud like better yield point viscosity and gel straight
It creates sufficient hydrostatic pressure in the hole and minimizes fluid loss by formation of thick filter cake on the walls of the well. Increase in density results in increasing the penetration rate; however, when the density is excessive, it can cause differential sticking of the string. It is chemically inert and insoluble. The overwhelming majority of the these [product that is mined is used by the petroleum industry as a weighting material in the formulation of mud. It increases the hydrostatic pressure of the dmud allowing it to compensate for high-pressure zones experienced during process. The softness of the mineral prevents it from damaging tools during production and enables it to serve as a lubricant
Barite in medical
An application where many people have heard of barite is within the medical field. A high-purity form of this chemcical is used in the gastrointestinal tract where its density prevents x-ray penetration, and thus is visible on an x-ray. It acts like x-ray shielding. It has emulsions properties for all kind of radioactive beam. The outline of the gastrointestinal tract thus becomes visible allowing the determination of normal and abnormal anatomy.
