Waste Management - WBM and drilling fluid performance
Water Based Mud (WBM) systems have been the traditional drilling fluids since the early days of the oil industry. Deeper, hotter wells, more deviated and with increasing well path tortuosity have brought the WBM systems to their limits of economic applicability.
1 Introduction
WBM systems are ranging from the classic Water-Bentonite suspension via the highly dispersive Lignosulphonate drilling fluids to the KCl-Polyglycol drilling fluid probably the most inhibitive WBM. Silicate Mud, may be the ultimate WBM system with the same inhibitive properties as OBM. Also, it . . .
