Water Based
Additives for water-based drilling mud
Water-based mud uses water or brine as its continuous phase, and its additives set the viscosity, fluid loss, inhibition and lubricity of the system. Galaxy Drilling Fluids Pvt Ltd supplies 68 additives for water-based mud, in its Water Based division.
What the range covers
It runs from the polymers that build viscosity and control fluid loss, through dispersants and shale inhibitors, to lost circulation material, lubricants, spotting fluids and the clean-up chemistry used at the end of the section. Each category below links to its own page, where the choice between grades is explained.
Product designations and classifications are those of the manufacturer. Descriptions explain the function of the chemistry and are not performance specifications. Technical data sheets and certificates of analysis are issued with quotation. Galaxy Drilling Fluids Pvt Ltd is a supplier of these products.

Frequently asked questions
What additives are used in water-based drilling mud?
A water-based mud normally needs viscosity and fluid loss control, and may need shale inhibition, thinning, lubricity and lost circulation material as the well requires. Galaxy Drilling Fluids Pvt Ltd supplies 68 additives for water-based mud across these functions.
When is water-based mud used instead of oil-based mud?
The choice depends on the formations, the temperature, environmental rules and cost, and water-based mud relies on inhibitors where oil-based mud would avoid shale reaction. Galaxy Drilling Fluids Pvt Ltd supplies additives for both, and can advise from the section being drilled.
