- Water-soluble bridging agents
- Added to saturated sodium chloride brine drilling fluids or
pills to assure temporary bridging and sealing of lost circulation
zones
DESCRIPTION
Plug-Sals are a series of specially
sized and treated salt. The Plug-Sal
products (Plug-Sal, Plug-Sal X, Plug-Sal
XC) have a wide distribution of particle sizes suitable for
bridging and sealing productive formations or sand control screens.
Plug-Sals resist caking in the bag and
disperse easily into brine systems. Plug-Sals are packaged in 50 lb or 25 kg
sacks.

BASE FLUIDS
Plug-Sals are used in
Bridgesal-Ultra® and
Thixsal-Ultra® Systems.
APPLICATIONS
Plug-Sal products are sized to
temporarily seal high permeability formations, vugular zones, or
completion assembly screens. Concentrations of 25-75 lb/bbl are
added to Bridgesal-Ultra or
Thixsal-Ultra fluid systems based upon the opening
size to be sealed.
