EZ-MUD PLUS

Description

EZ-MUD PLUS is a higher molecular weight version of EZ-MUD® with improved properties. EZ-MUD PLUS, a liquid polymer emulsion containing partially hydrolyzed polyacrylamide/polyacrylate (PHPA) copolymer, is used primarily as a viscosifier and borehole stabilizer to prevent reactive shales and clays from swelling and sloughing. The liquid form makes mixing easy. EZ-MUD PLUS is added to low-solids drilling fluids to increase fluid viscosity, and is also used to improve carrying capacity of air/foam injection fluids or low-solids fluids formulated with QUIK-GEL®.

Applications/Functions

EZ-MUD PLUS clear drilling fluid and QUIK-GEL®/EZ-MUD PLUS drilling mud system are cost effective and are applicable to all types of drilling and construction applications
- Water wells
- Instrument and observation holes
- Diamond coring
- Drilled shafts
- Minerals exploration
- Trenchless boring
- Seismograph shot holes
- Horizontal directional drilling (HDD)
- Blast holes
- Geo-construction
Stabilize water sensitive formations
Improve borehole and excavation stability
Enhance slurry rheological properties
Alleviate mud rings, bit balling and booting-off in clay formations
Reduce drill pipe torque and pumping pressure
Minimize rod chatter in diamond core drilling
Create "stiff-foam" and maintain foam integrity
Flocculate non-reactive solids in reserve pit
Reduce water loss effectively when added to pre-mixed QUIK-GEL ®slurry and other drilling mud systems

Advantages

Mixes easily with minimum shear in fresh water
Develops viscosity rapidly
Rapid settling of cuttings in pit-reduces recirculation of drilled cuttings back into the wellbore
Non-fermenting
Cost effective - small amounts produce desired results
Chemically degradable

Notes:
EZ-MUD PLUS can be chemically broken down with liquid bleach in regular household concentration (5% sodium hypochlorite). Use one gallon of liquid bleach per 100 gallons (10 liters/m3) of fluid formulated with EZ-MUD PLUS. Do not use perfumed liquid bleach or solid calcium hypochlorite.

Packaging

EZ-MUD PLUS is packaged in 5-gal (19-liter) and 1-gal (3.8-liter) plastic containers.
