Shale Inhibition: coats drill cuttings and allows for their removal by the solids control equipment before becoming dispersed in the active drilling fluid system

Viscosity: aids in hole cleaning

Flocculation: enhances the removal of drill solids

Lubricity: enhances performance and reduces torque and drag


DrillEase 242 shale inhibitor and rheology modifier can be used in freshwater, seawater and sodium or potassium chloride brines, and is very effective in sweeps to help enhance hole cleaning.

Treatment Recommendation

One quart or liter of the DrillEase 242 polymer should be pre-mixed in 300 gallons or 1 cubic meter of water. It can be added directly through the hopper, directly to the pit or down the drill rod during connections. For sweeps, the slurry should be poured down the drill rods, not the pipe. The container should be thoroughly agitated before product use.
