Bentonite (Bentonite) and water (Water) is main component of the importance of water, mud (Mud or Drilling Fluid) used in the drilling, exploration and production Petroleum Rotary (Rotary drilling. ) The properties of Bentonite when absorbing water and be able to swell to more 15-20. poured from the original volume Muddy water has a high viscosity and prevent through the well fluid. So popular additives bentonite clay in water to serve multiple Lube Trucks. Pound rock debris Reduce the loss of water, mud surface under pressure and stabilize the borehole. By the bentonite to be used the the fluid for drilling that meets the standards of the Institute of Petroleum Americans (American Petroleum Institute bentonite specification, API) set, in which the use of bentonite. In petroleum drilling in Thailand. Imports of bentonite and bentonite ore producers from around the world such as the United States. Groups independent country that seceded from the original Russian (CIS), Germany, Greece, Japan, China, Indonesia, etc., each of which is a source of physical and chemical properties vary depending on the desired utilization. Product and price The imports of these products are expensive, resulting in a trade surplus, foreign country greatly. For ore bentonite in Thailand. It is more common in Lopburi Sara Buri and Kanchanaburi The use of bentonite, a mineral that has been used in many ways, such as using a bleach or chemical absorption. The use of a filler (filler) to increase the amount of meat. Or used to adjust the viscosity for industrial paints and inks. Absorbent smell of waste from the body of the pet. The soil for planting, etc. in the field of exploration drilling has not been imported ore, bentonite is used widely in the country. Despite the physical and chemical properties of mineral bentonite in Thailand in the standard of API, so in doing this research study will compare the physical properties and chemical profile of bentonite from Thailand with bentonite. Scrapped imported from abroad in various grades. The comparison of mud mixed with bentonite ore from various sources. The effect of temperature changes. And to develop and improve the properties of mineral bentonite by the addition of other additives. To enhance the standards of the following API.
