ESM-D2™ is a deflocculant for water based drilling fluids. ESM-D2™ offers excellent dispersion of Micromax®, Microdense® and other weighting agents such as barite, especially for high density applications.

With ESM-D2™, drilling fluids of 3.00 SG (25 ppg) can be formulated at temperatues exceeding 230°C (446°F) providing stable drilling fluids with low rheological properties, minimizing the potential for sag.
