EZ-Mud Gold


EZ-MUD GOLD clay and shale stabilizer provides inhibition of clay and shale formations in water-based drilling fluids without substantially increasing viscosity. EZ-MUD GOLD stabilizer, when added to a QUIK-GEL  or BORE-GEL slurry, yields an inhibitive drilling fluid system while maintaining manageable and effective fluid properties. EZ-MUD GOLD stabilizer can be mixed easily at minimal shear thereby eliminating the need for liquid emulsions.

  • NSF/ANSI Standard 60 certified
  • Easy dispersion and mixing with minimal shear
  • Can be used at increased concentrations to gain inhibition without producing excess viscosity
  • No petroleum distillates present
  • Breaks down chemically with bleach (sodium hypochlorite)
  • Compatible with other Baroid drilling fluid additives when added in proper sequence
  • Non-fermenting



The use of EZ-MUD GOLD stabilizer aids or promotes the following:

  • Enhanced rheological properties of a low-solids drilling mud
  • Clay and shale stabilization to prevent swelling and/or dispersion
  • Borehole stability in water sensitive formations
  • Minimized rotational torque and circulating pressure
  • Enhancement of air-foam system capabilities
  • Enhanced core recovery in continuous wireline coring operations



Appearance: White, free-flowing beads

Using a Venturi Mixer, or into vortex of a high-speed stirrer, add slowly and uniformly to the entire circulating system.

Approximate Amounts of EZ-MUD GOLD stabilizer Added to Water Based Fluids
Drilling Application/Desired Property lb/bbl lbs/100 gal kg/m³
Added to fresh water (to formulate a clay-free drilling fluid)
  • To help stabilize water sensitive formation
  • To help reduce torque and lower circulating pressure
0.25 – 1.0 0.6 – 2.4 0.7 – 2.9
Added to QUIK-GEL or BORE-GEL drilling fluids
  • To help retard reactive shale and clay and enhance lubricity
0.1 – 0.3 0.25 – 0.75 0.3 – 0.9
Added to injection liquid in air/foam drilling applications
  • To help improve foam performance and hole conditions
0.25 – 1.0 0.6 – 2.4 0.7 – 2.9


  • Make-up water used to mix EZ-MUD GOLD stabilizer should meet the following quality:
    • total chloride less than 1500 ppm (mg/L)
    • total hardness less than 100 ppm as calcium
    • total chlorine less than 50 ppm
    • water pH between 8.5-9.5
  • Reduce total hardness of make-up water by adding soda ash (sodium carbonate) at 0.5 to 1 pound per 100 gallons (0.6 – 1.2 kg/m³) of make-up water.

EZ-MUD GOLD stabilizer can be chemically broken down with regular household liquid bleach (5% sodium hypochlorite). Use one gallon of liquid bleach per 100 gallons (10 liters/m³) of fluid formulated with EZ-MUD GOLD stabilizer.

Do not use perfumed liquid bleach or solid calcium hypochlorite.


EZ-MUD GOLD stabilizer is packaged in 10-lb (4.54-kg) and 40-lb (18.1-kg) plastic containers with re-sealable flip top lids.
