Application of Silicomanganese Fume as a Novel Bridging Material for Water-Based Drilling Fluids.

Steelmaking industrial waste, that is, silicomanganese fume (SMF), is one of the byproducts obtained during the steelmaking process in an electric submerged arc furnace at 1500 °C. Millions of tons of such wastes are generated yearly and used in different applications such as road construction, cement mortar, recycling into sinter plant, and so forth. In this study, the application of SMF in the drilling operations was investigated by employing SMF as a bridging material (BM) in water-based drilling fluid (WBF).
