BaraPure™ Fluid
Technical Capability
Requires salts, amines,
and/or silicate additives
plus glycols and polymers
to inhibit well, sub-par in
several situations
Technical Capability
Superior control of watersensitive and reactive
formations through CaCl2
salinity level.
Technical Capability
Equivalent to other IEF;
shale is controlled through
alcohol levels and
monitoring water activity.

Waste Management
Dewatering may be used
for water recycling. Salt
may cause disposal
concerns in some areas.
Waste Management
Containment of cuttings in
pits/skips. Dryer package
needed in some cases.
Waste is loaded onto trucks
and transported for
treatment/disposal.
Waste Management
Reduced waste and lowest
salinity value of any fluid.
Oil content can be reduced
further with dryers. Waste
can undergo on site land
treatment and disposal in
many areas.
