Standard Drilling Grade Bentonite

PRODUCT DESCRIPTION & APPLICATIONS

Bentonite is a natural Clay bentonite particularly suitable to all CE and drilling applications providing a Stable base Slurry requiring maximum tolerance to chemical contaminations from harsh subsoil and saline groundwater.

It is specially designed for ensuring the best performances in : -Bored piles, Diaphragm Walls, Cut-off wall constructions, Grout formulations. -Tunneling, Microtunneling and Pipe jacking. -All type of drilling : Oil&Gas, HDD, Waterwell, Minerals, Geotechnical and Coring.  -GCL production and Horizontal Soil Sealing. STARBENT 500, when adequately dispersed in sweet water, promptly develops excellent rheological, filtration and lubrication properties.

ADVANTAGES

  • Mixing quickly and easily
  • Stabilizes boreholes
  • Low grit content
  • Large number of applications

MIXING Pre-treat makeup water with soda ash to increase pH between 8.5-9.5 to maximize product performance.  The optimal dosage varies with each application, desired formulation, but usually ranges from 37-75kg/m3

PACKAGING AND STORAGE Available in 25kg bags on 1,000kg SWSP or jumbo bags. Stable under normal storage conditions in unopened containers.

Synthetic Viscosifier

Polymer is a versatile synthetic drilling polymer designed for building a low solid drilling fluid with increased borehole support for Deep Foundations, Tunnelling, Horizontal Directional Drilling, Mining, Water well & Geotechnical Drilling Fluids.  It improves borehole stability and maintains integrity of the drilled cuttings. Polymer is polyacrylamide high molecular weight anionic polymer in granular form.

Polymer encapsulates through a filming mechanism water reactive claystone, siltstone and mudstone, thus decreasing tendency to absorb water, swell and disperse.  thanks to its polymer long chain, bridges fine solid particles and effectively flocculates these aggregates to maintain a clear drilling fluid system.

ADVANTAGES

  • Easily mixed and dispersed
  • Stable in both fresh and saline water
  • Large number of applications

TYPICAL PROPERTIES

Appearance: Light yellow free flowing granular pH, as supplied: 7.0-10.0 Purity: mini 95%

MIXING

Pre-treat makeup water with soda ash to increase pH between 8-9 to maximize product performance. Add STARVIS HVP at low and steady state directly into mixer. The optimal dosage varies with each application but usually ranges from 0.5 to 3.0kg/m3. Worth to be noted that STARVIS HVP suspensions are shear sensitive.

PACKAGING AND STORAGE Available in 25kg bags on 1,000kg SWSP. Stable under normal storage conditions in unopened containers.
