Baker Hughes Drilling Fluids
Unlike mineral and diesel oils which are distilled from crude oils, synthetic type materials are usually
polymerized from ethylene. Since the synthetics are pure products made from ethylene, they contain
no aromatics, thereby lowering the toxicity level normally associated with aromatic compounds. Like
hydrocarbon oils, the synthetic type materials are more viscous than water. See Table 5-4 for the
properties of several synthetic materials.
