Go Devil II
Go
Devil II
is a blend of non-ionic polymers which provide low
shear rate viscosity (LSVR) in drilling fluid systems.
When mixed with fresh water, brines, or formates
it becomes a water soluble viscosifier providing
hole cleaning, solids suspension, and formation
invasion control.

Applications
Go Devil II’s use results in LSRV
Invasion Control properties which promote a low
solids, shear thinning fluid with increased rates
of penetration. Go Devil II is
compatible with most makeup water including brines
and formates. It is not generally affected by contaminants
such as salts, calcium or magnesium. Days on hole
are significantly reduced and significant reductions
in overall cost are typically realized. Go
Devil II has been used with excellent results
in many high angle and horizontal applications.
Go
Devil II is recommended in concentrations
of 3.5 to 5.0 lb/bbl for optimum performance in
most drilling fluid applications. Go Devil
II is recommended for use to:
-
Prevent formation invasion and damage
- Reduce
lost circulation
- Promote
borehole stability
- Eliminate
bridges
- Prevent
barite settling and sag
- Prevent
cuttings settling and fill
Go
Devil II is readily dispersible and can
be added directly to the drilling fluid through
a mud hopper.
Limitations
Go Devil II is an environmentally
safe dry powder. See the Material
Safety Data Sheet for more detailed information
concerning storage, handling, transportation, disposal
and safety requirements.
Packaging
& Storage
Go
Devil II is packaged in a special 25 lb
plastic pail designed to protect the product from
moisture.
