Surface Modifier to Improve Oil-Wetting of Drilling Mud

Cola®Teric AP-LP is a specialized surfactant additive to prevent water-wetting of solids. In specific applications, Cola®Teric AP-LP can reverse water-wetting of oil-wet solids that might occur. As a wetting agent, it may be pre-treated to a drilling fluid before displacement or cementing work has begun.
