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.
