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.
Application
MM SOD-BEN is used to increase viscosity and reduce fluid loss in fresh and sea water base drilling fluids.
Advantage
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.
Treatment
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.
