Rheology modifier SNPH-BP
Highly purified xanthan biopolymer with high rheological characteristics.
Advantages
- Possesses a high thickening capacity at low concentrations.
- Small amounts of biopolymer ensure high load-bearing capacity of solutions without a solid phase and minimal deposition of drilling mud under static conditions.
- Effective in fresh and mineralized drilling fluids.
Purpose
It is used as a structure-forming agent, regulator of rheological properties (plastic viscosity, DNC, SNC) of drilling fluids, for opening productive formations, especially during directional and horizontal drilling.
The biopolymer is a polysaccharide with high thixotropic characteristics; its rheological properties ensure a high shear rate in the composition of drilling fluids and sludge removal.
The recommended concentration is 0.5 to 5 kg/m³.
