(a) After a shoot & pull job and prior to
p.o.o.h.
(b) To control & cure losses before a workover,
before pulling completion string in case string is not
parted or has holes in it,

Mixing Procedure for Temperature
up to 250°F
Thixsal-Ultra Viscous
Carrier Fluid Preparation
Allow Pill to agitate for 10-15 mns prior to pumping downhole.
The Pill will be displaced downhole using Thixsal-Ultra
minimum 5bbls ahead and 10 bbls behind.
The Bridgesal-Ultra temp limitation
is 335°F Using the correct formula.
Pill volume normally needed is:
½ to 1 barrel per foot of open perfs + volume to
fill inside the casing from plug back total depth up to
+/- 100 to above top open perforation .
Note: The needed Thixsal-Ultra
as viscous fluid carrier ahead & behind should be mixed
using a concentration of 6 ppb in water .
