Product Description

DynaNite™ filtration control agent is a naturally occurring asphaltite-type mineral used for reducing HPHT filtrate values in oil- and water-based drilling fluids. The product disperses readily in any oil- and water-based drilling fluids supplemented with a wetting agent such as EvoCon® fluid conditioner.

DynaNite filtration control agent aids the prevention of stuck pipes in reactive formations.


While equally beneficial in oil- and water-based drilling fluids, DynaNite filtration control agent is especially effective as a shale stabilizer and filter cake conditioner in aqueous drilling fluids. In addition, it is particularly applicable for drilling low-pressured or depleted sands.

Treatment Recommendation

An initial treatment of 2-6 lb/bbl is recommended. When mixed in a water-based drilling fluid, EvoCon fluid conditioner can be added to preferentially water-wet the DynaNite filtration control agent. The incorporation of EvoCon additive minimizes the tendency of the mineral to agglomerate and be removed by fine shaker screens.
