• Oil-emulsion mud

  A water-base mud in which water is the continuous phase and oil is the dispersed phase. the oil is spread out, or dispersed, in the water in small droplets, which are tightly emulsified so that they do not settle out. because of its lubricating abilities, an oil-emulsion mud increases the drilling rate and ensures better...

• Oil mud

  A drilling mud, e.g., oil-base mud and invertemulsion mud, in which oil is the continuous phase. it is useful in drilling certain formation that may e difficult or costly to drill with water-base mud. compare oil emulsion mud....

• Emulsion

  A mixture in which one liquid, termed the dispersed phase, is uniformly distributed (usually as minute globules) in another liquid, called the continuous phase or dispersion medium. in an oil-water emulsion, the oil is the dispersed phase and the water the dispersion medium; in a water-oil emulsion, the reverse holds. a typical product of oilwells,...

• Oil-base mud

  A drilling or workover fluid in which oil is the continuous phase and which contains from less than 2 percent and up to 5 percent water. this water is spread out, or dispersed, in the oil as small droplets. see oil mud....

• Nonconductive mud

  Any drilling fluid, usually oil-base or invert-emulsion muds, the continuous phase of which does not conduct electricity, e.g., oil....
