STAR-DET PLUS
STAR-DET PLUS drilling detergent is a liquid blend of specialty surfactants designed to reduce the surface tension of water base mud systems and reduce the sticking tendency of reactive shale and clays
Application
STAR-DET PLUS reduces torque and drag and is used primarily in surface and intermediate sections during drilling to minimize bit and BHA balling and mud rings. STAR-DET PLUS is effective in all water base systems including freshwater, brackish water, seawater and saturated saltwater fluids.
Advantages
- Minimizes bit and BHA balling
- Improves water-wetting action on all solids and reduces the sticking tendency of reactive shale cuttings
- Functions as an emulsifier, reducing the viscosity of oil-contaminated fluids
