n: a drilling fluid containing man-made chemicals that emulate natural oil. Natural oil-base muds require that the cuttings made by the bit be specially handled to prevent damage to the environment;synthetic muds were therefore developed to replace oil-base muds in environmentally sensitive areas. For this reason, synthetic- based muds are sometimes termed pseudo-oil-base mud. See oil-base mud.
