to stabilize clay and shale formations and as a viscosifier. TBC-PHPA is packaged in 25 kg sacks.
BASE FLUIDS
TBC-PHPA can be used in fresh or
brackish waters.
ADVANTAGES
- Effective in very small concentrations
- Reduces bit-balling
- Aids in lubrication
- Increases the yield of bentonite
- Increases viscosity
- Non-fermenting
MIXING INSTRUCTIONS
TBC-PHPA should be added slowly through
a conventional mud hopper to avoid fish-eyes and lumping. Typical
concentrations range from 0.25 to 1.0 lb/bbl.
