  • bentonite - Schlumberger Oilfield Glossary

    A material composed of clay minerals, predominantly montmorillonite with minor amounts of other smectite group minerals, commonly used in drilling mud.Bentonite swells considerably when exposed to water, making it ideal for protecting formations from invasion by drilling fluids. Montmorillonite forms when basic rocks such as volcanic ash in marine basins are altered.

  • Bentonite for drilling fluids | Bentonite

    Bentonite is used for drilling fluids preparation. When mixing with water bentonite clay forms a viscous gelled suspension which serves as a basis for drilling fluid. During borehole construction, drilling fluid flushes the bore hole to clean it out from cuttings, lubricate and keep the drill bit cool and for other specific purposes of drilling. An important property of bentonite-based

  • Drilling Fluids | Minerals Technologies Inc.

    All CETCO bentonite based drilling fluids are made of the highest quality sodium bentonite from Wyoming . When drilling with bentonite, a protective "filter cake" is formed on the borehole wall reducing the level of soil permeability and increasing stability. The circulating bentonite slurry removes the drilled cuttings bringing them to the surface. The bentonite mixture also exerts

  • Drilling fluid - Wikipedia

    Drilling fluid carries the rock excavated by the drill bit up to the surface. Its ability to do so depends on cutting size, shape, and density, and speed of fluid traveling up the well (annular velocity).These considerations are analogous to the ability of a stream to carry sediment; large sand grains in a slow-moving stream settle to the stream bed, while small sand grains in a fast-moving

  • How Do I Use Bentonite-Free Polymer HDD

    Most pre-packaged, bentonite-free liquid polymer drilling fluid products consist of four basic components, starting with a base product that serves as a replacement for bentonite. Then you have additives for sand and clay, and a clay drilling detergent or clay dispersant. These last three products, in varying amounts, adjust the base drilling fluid to the different soil conditions, similar to

  • Four Steps to Mixing Good Drilling Fluid –

    To get the most from your bentonite fluid, you should be using warm, soft water. Otherwise, you risk inhibiting the performance of the bentonite and any polymers you're adding to it. Because warmer water works the best, Layman has heard some drillers in cold climates run heated water into their water tanks at 100ºF or more. Adding soda ash to the makeup water softens the water and raises

    The drilling fluid should consist of water and bentonite, a clay material that absorbs free water into its structure while maintaining its consistency. When the ground is already stiff, firm, and impermeable such that drilling fluid cannot penetrate the interstitial spaces, the percentage of bentonite can be reduced. However, introducing conditioners and additives to the slurry is beneficial
