Emulsifiers
Emulsifiers for drilling fluids
An emulsifier holds water droplets inside the oil in an invert emulsion mud, so that the two stay one stable fluid. Galaxy Drilling Fluids Pvt Ltd supplies 9 products in this category: 8 for oil-based mud and 1 oil-in-water emulsifier for water-based mud.
Primary and secondary emulsifiers
A primary emulsifier forms the emulsion. A secondary backs it up and helps keep solids oil-coated. The range carries GS Mul P and Gel Mul S in that pairing, with GS Mul PAM and Gel Mul SAM as winterized grades that stay pourable in cold weather, and GS Mul Pro as a premium secondary that is more tolerant of solids and contamination.
Simpler or more demanding systems
GS Mul Ai1 replaces a package with one product, which simplifies stock and mixing, and has an HT grade for hot wells. GS Mul HP suits very salty internal brine, as primary or secondary. Puro Mul is a concentrated emulsifier for clean, low-additive systems. Powdered equivalents are in the Polvo Series.
For water-based mud
GS Oil-Merge works the other way round: it blends oil into water-based mud to improve lubricity and filter cake.

Frequently asked questions
What is the difference between a primary and a secondary emulsifier?
A primary emulsifier holds water droplets inside the oil and forms the invert emulsion. A secondary emulsifier backs it up and helps keep solids oil-coated. Galaxy Drilling Fluids Pvt Ltd supplies both, as GS Mul P and Gel Mul S among others.
Is there a single-product emulsifier for oil-based mud?
Yes. GS Mul Ai1 is one product in place of an emulsifier package, which simplifies stock and mixing, and has an HT grade for hot wells. Galaxy Drilling Fluids Pvt Ltd also supplies a powdered version, POLVO MUL Ai1.
