Features and Benefits

MM SOD-BEN is used as a primary filter cake building filtration control and suspension agent in

fresh water systems and has application in most water-base fluid systems.

MM SOD-BEN provides thin, impermeable and compressible filter cake in the wellbore.

MM SOD-BEN is a cost effective product for achieving viscosity.


MM SOD-BEN is used to increase viscosity and reduce fluid loss in fresh and sea water base

drilling fluids.


The additives in the treated bentonite dissolve under high temperature and pressure and cause the

well to be clogged and various drilling mud problems

Furthermore, since water loss is high in treated bentonite, this increases the use of various

chemicals and this makes it dissicult to control drilling mud.

Sodium bentonite being non treated and natural, having high viscosity having low water loss

minimize the use of these chemicals and therefore this reduces the cost of drillings mud.


Normal treatment levels range from 5 to 25 Ib/bbl (14-70 kg/m3). The concentration will vary

depending on the fluid composition as well as desired viscosity and suspension characteristics.

MM SOD-BEN is added slowly and uniformly through the mud hopper.



MM SOD-BEN is supplied in 50 kg (100 lb) multi-wall paper sacks or in 1 MT big-bag.
