TUNNEL-GEL PLUS viscosifier is a specially formulated, high-yield bentonite designed for use in tunneling and large diameter HDD operations. 

TUNNEL-GEL PLUS viscosifier promotes rapid viscosity development while maintaining effective borehole stabilization and enhanced filtration control in most water-based drilling fluids. 

Applications and Functions

  • Enhanced viscosity development in freshwater drilling fluids 
  • Effective cuttings transport and suspension characteristics 
  • Enhanced filtration control and resulting borehole stability 
  • Effective lubrication fluid for microtunneling operations

Advantages

  • Easy to mix and quickly reaches maximum viscosity 
  • Enhances fluid lubricity for reduction of required jacking forces 
  • Yields more than twice as much drilling fluid of the same viscosity as an equal concentration of API grade bentonite
