Clay-Stop is a concentrated, non-hazardous, proprietary clay inhibitor that can be used with either polymer or bentonite drilling fluid systems.

ADVANTAGES

• Greatly reduces clay rings and bit balling
• Increases returns to the surface
• Non-hazardous
• Readily dispersible
• Reduces pullback pressures
• Reduces torque

PROPERTIES

Appearance            Clear to light amber/pale yellow.
Odor.                        Faint amine odor.
Odor threshold.     Threshold not determined.
pH                             6.5-8

APPLICATION

Clay-Stop is to be used on any size HDD bore. Using Clay-Stop will greatly reduce or eliminate clay cuttings from sticking to each other and to the drilling tools.

MIXING

Treatment

• ¼ gallon of Clay-Stop treats 500 gallons of water

Recommended Fluid Formulation For Drilling In Clay (per 500 Gal)

• 2 LBS Soda Ash

NOTES:

Clay-Stop should be added to the drilling fluid system last. For sticky and swelling clays use 0.25 to .5 gallon per 500 gallons (2 to 4 liters/4 m3) depending on water sensitivity of the formation.

For maximum effectiveness, Clay-Stop should be used starting with the pilot hole and all reaming and pullback stages. Clays begin swelling and absorbing water immediately upon contact with water starting with the pilot hole. Clay-Stop will eliminate or greatly reduce this problem.

Sand Zan P is a premium quality, powdered biopolymer that is used to enhance the carrying capacity of both clay and polymer-based drilling fluids. Sand Zan P is easily dispersible in fresh or brackish water.

ADVANTAGES

• Can mix easily into pre-hydrated bentonite-based fluids
• Helps enhance system by increasing the suspension properties of the base drilling fluid with a minimal increase in viscosity
• Small packaging for ease of handling and reduction of waste

PROPERTIES

Appearance                                Free-flowing beige powder

Specific gravity                          1.6

Bulk density (lb/ft3 )                45

pH (0.14% or 0.5 lb/bbl)         7.1 – 7.4

APPLICATION

Increased gel strength of the drilling fluid for better suspension of the drilled cuttings, coarse sand and gravel. Enhanced carrying capacity for solids suspension at lower viscosity to further ensure flowability on longer length bores and backreams.

MIXING

Treatment

• 3 to 5 pounds of Sand Zan P treats 500 gallons of water
• Best If Used with Other Velocity Products

Recommended Fluid Formulation sand and cobble (Per 500 Gal)

• 2 LBS Soda Ash
• 50 LBS Gel

NOTES:

Sand Zan P can be added to enhance the suspension capability of the fluid. Sand Zan P enhances the wall cake to keep the formation better isolated. Add soda ash at a rate of 1 LBS per 100 gallons to treat water prior to mixing other additives. Soda ash will enhance the yield of your additives.
