PF-VIS：Viscosifier For Drilling  Fluid

Overview：

PF-VIS is a class of natural polysaccharide polymers. It is easily soluble in water. A small addition can significantly improve the viscosity.

Characteristics：

Strong salt resistance；Increase viscosity at low shear rate；Acid and alkali resistance；Good dispersion in drilling fluid Temperature：≤150℃

PF-EZVIS：Viscosifier For  Drill-in Fluid

Overview：

PF-EZVIS is a viscosifier suitable for reservoir drilling fluids. It is easily soluble in water, and has good dispersibility. It is a chain   polysaccharide polymer with small molecular weight and high viscosity. It is a high-efficiency thickener suitable for fresh water, salt water and saturated salt water drilling fluids.

Characteristics：

Strong salt resistance；Increase viscosity at low shear rate；Strong shear thinning Special for EZFLOW Non-Gel Breaking Water-based Drill-in Fluid.Temperature：≤150℃

PF-FSVIS：PF-FSVIS Rheology Modifier

Overview：

PF-FSVIS is an amide polymer that can be used as a rheology modifier for synthetic based drilling fluids. PF-FSVIS does not affect the viscosity at low temperatures, but increases fluid viscosity at high temperatures. This can effectively ensure a flat rheological profile of synthetic base drilling fluids.

Characteristics：

Effectively improve cuttings carrying capacity and hole cleaning efficiency of drilling fluid；Good compatibility with drilling fluid; Improve emulsion stability Special for FLATPRO Deep Water Flat Rheology Synthetic Based Drilling Fluid.Temperature：≤160℃
