Polyanionic polymer Cellulose PAC-LV/HV

Polyanionic lose

Polyanionic lose short for PAC,It is a high quality water soluble lose derivative. In shape of white or light yellow free-flowing powder, it is odorless, tasteless, non-on-fermented, and has good thermal-stability and high salt resistance.

Polyanionic lose is soluble into water to form thick liquid, and it widely used in water-base drilling fluid so as to enhance the drilling fluid viscosity and control the fluid loss. Usually the sodium salt of Polyanionic lose is in application and widely used in petroleum drilling, especially in salt well and offshore oil drilling.

Polyanionic lose used in the fracturing fluid, Polyanionic lose can efficiently carry ‘the filler’ into the cracks of well, establish the permeability pathway, which can effectively control the fluid into the well structure, reduce the fluid loss, and reduce the pressure drop. Ultra-high viscosity products can replace guar gum, reducing production costs.
