Viscosifier
Viscosifier for drilling fluids
A viscosifier raises the viscosity of a drilling fluid so that it can lift cuttings out of the hole and hold solids in suspension when the pumps stop. Galaxy Drilling Fluids Pvt Ltd supplies 10 products in this category: 7 for water-based mud and 3 for oil- and synthetic-based mud.
Choosing a grade for water-based mud
The choice mostly follows temperature and salinity. Modified starch is the economical starting point and also holds water in the mud; carboxymethyl and high-temperature starch grades extend it into heavy salt, calcium and hotter sections. PHPA thickens the mud and coats cuttings so they stay intact. Where ordinary polymers break down, the high-temperature polymer grades keep carrying capacity in deep sections.
Choosing a grade for oil-based mud
Invert emulsions need different chemistry. GS Vis-FLT is the main thickener for oil- and synthetic-based mud, GS Vis IS keeps barite from settling, and GS Vis SF suits clay-free systems where the aim is flat rheology, with thickness staying even as temperature and pressure change. The Polvo Series carries a powdered flat-rheology grade as well.

Frequently asked questions
What is a viscosifier used for in drilling mud?
A viscosifier thickens drilling mud so that it carries cuttings to surface and keeps weighting material and solids suspended when circulation stops. Galaxy Drilling Fluids Pvt Ltd supplies starch, PHPA and high-temperature polymer grades for water-based mud, and dedicated grades for oil- and synthetic-based mud.
What is PHPA in drilling fluid?
PHPA is a polymer used in water-based mud. It thickens the fluid and coats cuttings so that they do not crumble as they travel up the hole. Galaxy Drilling Fluids Pvt Ltd supplies it as the GS Drill Series, in liquid, powder and cationic grades.
Which viscosifier grades are made for high-temperature wells?
In this range, GS Starch HT, GS Temp HTL, GS Vis WHT and GS Viscal HTR are the grades for hot water-based sections. The temperature limit of a particular grade is stated on its technical data sheet, which Galaxy Drilling Fluids Pvt Ltd issues with quotation.
