features and Benefits
Use for:
Water control in EPB chamber;
Caisson Sinking, Pipe and Structure Jacking (in conjunction with
TK60 polymer);
Tunnel Face Conditioning - Mud and Slurry Loss Control for Rotary
and Directional Drilling
Less than 1/2 kg of product makes a cubic metre of slurry!
Semi-solid - yet pumps readily via a diaphragm or mono pump.
When hydrated will not damage or block pumps or downhole
motors.
Caisson/jacking formula with TK60 prevents clay swelling
Forms a super-lubricating, easily pumpable structural-gel filler
against migration of sand and fines into the annulus or plenum.
Lumpy consistency resists lubricant loss to loose ground
Displaced readily by grout, the calcium/alkali chemistry of
which also degrades the anti-friction properties of any remaining
polymer film.
Low slump semisolid: avoids catastrophic loss if major leak path
opens.
Soft setting solution can be applied behind the bottom ring of
segments prior to underpinning at rock-head.
Degradable, non toxic, safe in use
Very low visual and environmental impact if accidentally
released into water bodies
Can be used in conjunction with foam, polymers or bentonite.
Unlike all other common lost circulation materials, SLOOP EC
will not foul pump valves, plug screen separation equipment, or
impede or damage downhole motors or other complex equipment. The
optimum choice for slurry tunnelling, MWD and directional
drilling.
Can be formulated as an air stop in CSM-Bessac type
headings.

How To Use
RECIPE FOR ONE CUBIC METRE OF THICK LUBRICANT (VARY AS
REQUIRED):
Fill paddle mixer or pumped recirculating tank with water. Add 2
litres of TK60 Liquid. Mix 2 minutes. Add 2 kg of Sloop Powder. Mix
10 - 20 minutes. Pump as required.
Notes for using in HDD applications
General preparation: Prepare a separate fresh water or
water/polymer slurry at a rate of 1 to 4 kg per cubic metre. 1 kg
dry sloop = approx 1 litre/ 1 us quart measured volume 1 cubic
metre = 220 us gallons
Important
If used with a mud motor or other equipment having
restricted flow paths, ensure that the sloop granules are fully
hydrated before pumping. This will take 15 to 40 minutes. When
fully hydrated the granules will be soft, easily squeezed flat, and
transparent.
Lost circulation:For partial losses, or to prevent mud loss, add
gradually to the circulating mud. For severe or total losses,
prepare thick slurry comprising your existing mud formula plus 2 to
3 kg of sloop per cubic metre
Borehole stabilisation: Sloop is compatible with morrison tk60
and mx borehole conditioning agents.Use in conjunction with
morrison mx polymer to help stabilise sands and gravels.
Safety
Low toxicity, safe in use. Employ normal industrial hygiene.
Slippery underfoot when wet - clean up at once.
