PETROLEUM AND NATURAL GAS INDUSTRY
Worldwide used Barite’s 85-90% of it is used in petroleum industry. Especially, after 1926 Barite is started to be used highly in petroleum and natural gas searches. In world, barite is mostly used in petroleum drillings in order to make the mud heavier. This mud is actually very useful as in during the drilling it helps the residuals which are belong to the processed formations to reach top, oiling of the drills and rods, firming of the drilling hole walls and when the drilled oil becomes close to the expected levels balancing the pressured gas advancement. Drilling mud also provides balance against the rod’s increasing weight when the well gets deeper. Barite’s abilities of high weight density, soft and nonabrasive, being stable against high pressure and heat, not melting in water and be supplied with low cost makes it an ideal material for the drilling mud.
