- Prevents the adverse effects of cement contamination in
biopolymer systems
DESCRIPTION
CM-TH is an inorganic salt which serves
as a complexing buffer. Packaging is in 50 lb or 25 kg
sacks.
BASE FLUIDS
CM-TH may be used in fresh water, sea
water, sodium or potassium chloride brines.
APPLICATIONS
CM-TH is an excellent pre-treatment
additive to prevent cement contamination of fluid systems
containing biopolymer without otherwise affecting rheological or
filtration properties.
MIXING INSTRUCTIONS
CM-TH should be mixed rapidly using a
conventional mud hopper or other adequate mixing arrangement.
Normal pre-treatment is 3 lb/bbl or if the volume of cement to be
drilled is known, CM-TH can be added to
the fluid at 250 lb/bbl of cement to be drilled.
