TriVis
is a primary rheology additive that provides low
shear rate viscosity (LSRV) non-aqueous drilling,
workover and completion fluids. When mixed with
oils or oil base muds, it provides hole cleaning,
solids suspension and formation invasion control.
Addition of TriVis
results in LSRV Invasion Control properties which
promotes low solids, shear thinning for increased
rates of penetration.
TriVis
is used in POLYPHRON
fluids to reduce formation damage, reduce lost circulation,
promote borehole stability, eleminate bridges, fill
and barite settling. loss and formation invasion
is dramatically reduced. TriVis
cP+ can be used in POLYPHRON
fluids with excellent results in drilling highly
permeable, low-pressure depleted zones.

Applications
TriVis
rheology additive is recommended in concentrations
of 8.0 - 20.0 pounds per barrel for use in most
oils or synthetics. TriVis is used
as the primary rheology additive to enhance LSRV
in OBM or SBM.
TriVis
can be added directly to the oils or OBM through
a mud hopper. Although TriVis
readily yields in most non-aqueous fluids, care
should be taken to add
TriVis slowly. TriVis
will continue to yield for several hours, use care
to avoid over treating.
TriVis
is compatible with most non-aqueous fluids including
crude oil, diesel, mineral oil, vegetable oil and
synthetics. It is also effective in oil base muds
(OBM) and synthetic base muds (SBM).
