FORMATE STABILIZER
DESCRIPTION

Formate Stabilizer is a low molecular weight polyglycol blend formulated to stabilize rheological and filtration control properties of polymer systems formulated in formate brines. Formate Stabilizer is recommended for use where bottom hole temperatures exceed 325°F. Packaging is in 55 gal steel drums and 5 gal plastic containers.

BASE BRINES
Formate Stabilizer can be mixed in sodium, potassium, or cesium formate brines.

MIXING INSTRUCTIONS
Normal treatment is 1 - 3% by volume of Formate Stabilizer mixed into the system.
