POWERVIS Linear Biopolymer Viscosifier

Overview Library

Unique rheology profile that provides higher thermal stability and lower ECD

The innovative chemistry of POWERVIS viscosifier delivers lower pump pressures and ECD, making it an ideal alternative for coiled tubing drilling or any applications where a solids-free system is being used.

Optimal characteristics with less product

Compared with xanthan-gum biopolymers, the POWERVIS viscosifier offers a range of advantages:

  • similar low-shear-rate viscosities at lower concentration levels
  • lower plastic viscosities and yield point
  • lower ECD, pressure loss, and free-spin pressures in coiled tubing operations
  • more resistance to thermal degradation while tolerating cement and higher pH.

Integration capabilities for enhanced efficiency

The POWERVIS viscosifier can be used

  • as a rheology-modifying agent in POWERPRO CT coiled tubing debris-removal fluid to provide viscosity and solids suspension
  • as a vicosifier in FLOPRO NT water-base reservoir drill-in fluid in fresh-water or low-salinity drilling fluids where enhanced hole cleaning is desired
  • in SAFETHERM aqueous-base water-miscible insulating packer fluid applications.
