EZ-Mud DP

BOREHOLE STABILIZING DRY POLYMER

EZ-MUD DP borehole stabilizing dry synthetic polymer contains high molecular weight partially hydrolyzed polyacrylamide/polyacrylate (PHPA) copolymer. EZ-MUD DP water-soluble polymer, when mixed with fresh water, hydrates quickly and forms a clear, viscous fluid. EZ-MUD DP dry polymer provides excellent borehole stability through a coating mechanism (encapsulation).

• Can disperse easily with minimal shear; non-fermenting
• Efficient shale/clay stabilizer and viscosifier; helps impart high degree of lubricity
• Compatible with other drilling fluid additives when added in proper sequence
• No petroleum distillates involved
• Breaks down chemically with bleach (sodium hypochlorite); NSF/ANSI Standard 60 Certified

 

The use of EZ-MUD DP dry polymer assists and promotes the following:

• Stabilize reactive clay and shale formations
• Keep trench excavation open during the construction
• Produce high viscosity solids-free slurry
• Enhance rheological properties of a low-solids drilling mud
• Enhance core recovery in continous wireline coring operations
• Flocculate non-reactive solids in reserve pit at low concentrations ? Reduce torque and drag

Added to QUIK-GEL or BORE-GEL Drilling Fluids
To help retard reactive shale and clay and enhance lubricity	0.25 – 0.75	0.1 – 0.3	0.3 – 1.0
Added to injection liquid in air/foam drilling applications
To help improve foam performance and hole conditions	0.5 – 1.0	0.2 – 0.4	0.6 – 1.2

Notes:

• Make-up water used to mix EZ-MUD DP polymer, viscosifier or additive should meet the following quality: total chloride less than 1500 ppm (mg/L) total hardness less than 150 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 DP polymer, viscosifier or additive 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 DP polymer, viscosifier or additive. Do not use perfumed liquid bleach or solid calcium hypochlorite.

 

EZ-MUD DP polymer, viscosifier or additive is packaged in 14-lb (6.4-kg) resealable plastic containers as well as 50-lb (22.7-kg) and 25-kg (55-lb) multiwall paper bags.
