Claims10
A drilling mud conditioning additive composition comprising a blended admixture of synthetic graphite having a particle size of less than 20 microns and constituting 56.5% of the mass of the composition, phlogopite substantially free of mica, silica and other mineral impurities and having a particle size distribution in which all the particles are less than 45 microns in size and 95% thereof are less than 25 microns in size and a 30% emulsion of dimethylpolysiloxane in water, said dimethylpolysiloxane enhancing the hydrophobic properties of the graphite and the phlogopite.
A drilling mud conditioning additive composition comprising a blended admixture of graphite, a silicate mineral selected from the group consisting of vermiculite, biotite, serpentinite, muscavite, phlogopite, eastonite, mica, and mixtures thereof and a silicone material, said silicone material enhancing the hydrophobic properties of the graphite and the silicate mineral.
