SILICATE-BASED DRILLING fluids have been used to drill successfully1,2 through a wide range of troublesome shales in various parts of the world. With the advent of stringent environmental regulations and foreseen phasing out of oil-based and synthetic-based drilling fluids, current petroleum industry efforts are focused towards finding alternate environmentally acceptable water-based drilling fluids.
With this in view, silicate-based systems are being used extensively in the oil and gas well drilling industry. Silicate-based fluids are therefore replacing oilbased/ synthetic-based muds (OBM/SBM) in a wide range of applications where troublesome clay-bearing formations such as shales and claystones are to be drilled. The mechanisms by which OBM/SBM inhibit the hydration of
shales have been reviewed here, as is the failure of common water-based muds (WBM) to duplicate the success of OBM/SBM in drilling these troublesome formations.
