PENETROL® water miscible; non-ionic wetting agent is designed to counteract the sticking tendencies of clay. Applications/Functions: Can reduce or eliminate bit balling; Can reduce surface tension of drilling fluid; which allows faster chip removal without continuously grinding the hard shale formations; Can improve drilling efficiency by preferentially coating the bottom-hole assembly and drill string; Can minimize differential sticking; Can increase bit life and reduce drill pipe and bottom-hole assembly wear. Advantages: Easy to mix; Effective in low concentrations; Compatible with other Baroid drilling fluid additives; Biodegradable; NSF/ANSI Standard 60 certified.
