EZ-Mud Gold

CLAY/SHALE STABILIZER

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

APPLICATION

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

TYPICAL PROPERTIES

Appearance: White, free-flowing beads

MIXING & HANDLING

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

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

Note:

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.

PACKAGING & CONTROLS

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.
