Description

Oilfield chemicals sodium lignin sulfonate is a soluble additive that provides thin low permeability filter cakes accompanied with low fluid loss.

Application

Oilfield chemicals sodium lignin sulfonate powder may be used for rheology and filtration controls in water base mud's and for helping maintain a constant pH. Sodium lignin sulfonate is especially effective at stabilizing the property of mud's exposed to high temperatures and contaminations. Could reduce the viscosity of mineral slurries is used to advantage in oil drilling mud, where it replaced tannic acids from quebracho.
