Xanthan Gum provides optimal viscosity characteristics Fluids in drilling, work-over,and completion operations. Optimum fluid performance is achieved when viscosity is minimized at high flow rates,such as at the drilling bit)and when viscosity is increased at low flow rates(as in the annular region),and under static conditions.
Welan Gum is excellent viscosifier and suspending agent in aqueous brines.It is compatible with cement slurries and it could greatly increase the suspension properties of cement slurries. Many other polymers are not compatible or well functional in cement slurries. The compatibility and suspension properties made welan gum advantageous in several oilfield and industrial applications.
