MILZAN D
MILLZAN D is a dispersible, high molecular weight xanthan biopolymer used for rheology control in water based systems. MILLZAN D is used primarily as a viscosifier in fresh water, seawater or saline muds, from low solids to highly weighted systems. It will enable optimum rheology control through superior low shear rate viscosity and is highly shear-thinning.
Application
Easily mixed to provide rheological properties for improved hydraulics. This includes minimum friction pressures for additional hydraulic horsepower at the bit for maximum ROPs. The same rheology promotes laminar |ow in the annulus for increased borehole stability with maximum solids transport capacity. Will function in fluid temperatures up to 138°C. The addition of 3% salt and an oxygen scavenger will improve temperature stability in fluids from 94°C to 138°C.
Advantages
- Can be used as a low end rheological booster
- Increased yield point and gel strengths
- Stable up to 138°C
- Biodegradable
