Bentonite Supplier for Oil Field Industries. It is a drilling-grade Bentonite which is naturally occurring clay. It is a High Yield Natural Sodium montmorillonite. It meets API 13A Standards. Bentonite, is a very fine grind material mostly a composite of clay minerals, especially montmorillonite which chemically describes as hydrous alumina-silicate and contains small amounts of alkali and alkali-earth metals.
• It is Viscosifier and Filtration control agent for water based Mud Systems.
• It is used in drilling muds for controlling bore hole stability. It is utilized in drilling muds to extract drill cuttings from the bit.
• It is also used for clearing cat litter
Bentonite, sometimes refer as sometimes referred to as Montmorrilonite is a naturally occurring substance, composed of a number of layers, each approximately 10 angstroms thick, and each consisting of two tetrahedral and one octahedral unit. This structure is responsible for three important characteristics, the ability to absorb large amounts of moisture, the ability to exchange ions and thixotropic gel formation.
Advantage
• It helps improve hole cleaning capacities of drilling fluids.
• It is effective as a filtering agent.
• It promotes borehole stability.
• It can be added directly to fresh water or fresh water based drilling fluids.
