New Vis / Xan Vis

Description

NEW VIS is a polymeric viscosifying agent for freshwater, seawater and sodium chloride and potassium chloride brines.

Application

Additions of NEW VIS yield shear thinning fluids. Viscosity is low at bit shear rates to optimize penetration, and is high at low annular shear rates to provide maximum hole aging.

Recommended treatment

NEW VIS should be mixed thought the mud hopper at 25 to 30 minutes per sack to prevent “ balling” and “ fish eyes”. A bactericide is needed to prevent biodegradation in freshwater and seawater fluids. Concentration of 1,43 to 2,85 kg/m3 (0,5 to 1,0 lb/bbl) are normally added to provide adequate viscosity.
