摘要： This invention relates to an additive which increases the density of wellbore fluids used during the construction or repair of oil, gas, injection, water or geothermal wells. According to the invention, the additive is comprised of solid colloidal particles of weight average particle diameter (D50) of less than 2 microns, the particles being deflocculated by the action of a dispersant, preferably incorporated during the process of grinding or comminution of the particles to the specified particle size. The additives of this invention may be used in any wellbore fluid such as drilling, cementing, completion, packing, work-over (repairing), stimulation, well killing, and spacer fluids as well as in a dense media separating fluid or in a ship's ballast fluid.
