Made for Drillers. By Drillers.

Australian drilling fluids formulated for industry

At Mudex, generic doesn’t cut the mud – our Australian made drilling fluids are specifically designed and tested for unique industry applications. Whether your mud requirements are for geotechnical, mining, water well, HDD or drill and blast applications – our products combat unique issues across all ground types – making sure you get more out of your mud.


With drill hole performance at the fore of our drilling fluid innovation, our range of drilling products consider the varying geologies and water qualities that present themselves in the specific industries we work with.

Specially designed for extreme environments, particularly where high shear stress and temperatures, water quality and other contaminants can severely impact performance of stock-standard polymers are Mudex’s patented VIS range of polymers.

Extensive field and laboratory testing has ensured the VIS range polymers are exceptional performers in all applications of drilling, water types (from fresh water through to hyper saline) and additionally possess the capability to perform against a broad range of contaminates and pH levels.

Frequently Asked Questions

What drilling fluid should I use?

When choosing a drilling fluid there are a number of factors to consider – there is no one fluid for all applications.

a. Identify the method of drilling:

    1. Diamond Drilling
    2. WaterWell Drilling
    3. RC or Conventional Air Drilling
    4. Blast Hole Drilling
    5. Geotechnical Drilling

b. Assess geological ground formation you expect your hole to encounter.

c. Once these parameters are understood, a Mudex mud specialist can assess and recommend drilling fluid product options.

What is the first step in choosing the correct drilling fluid?

There are a few considerations to factor in when choosing a drilling fluid, one of the first steps is to obtain a water sample that the drilling fluids will be mixing with to ensure suitability for that water type.
