Ferro Chrome Lignosulfonate (FCL)

Description

FCL is a multi – purpose, ferro - chrome – treated sodium lignosulfonate for use in water base mud.

Application

FCL is used as a deflocculant and filtration control agent at alkaline PH in water based system, including fresh, salt and calcium – treated water base mud. FCL provide excellent thermal stability for the control of rheological and filtration properties. FCL will also inhibit the reactivity of clay solids when used in proper concentration. FCL is commonly used to prevent salt flocculation of bentonite and to reduce the effect of high temperature gellation in bentonite fluids.

Recommended treatment

FCL treatment of 2.9 to 8.6 kg/m3(1 to 3 lb/bbl) are normally sufficient for deflocculant of fresh water system. Sea water muds may require levels of 11.4 to 17.1 kg/m3 (4 to 6 lb/bbl) for satisfactory control of fluid properties. Optimum perfomence of FCL is obtained at PH from 9.5 – 10.5 adjusted by caustic soda.
