Aliphatic Compound
Aliphatic Compound : (n.) Drilling Fluids. One of a group of organic compounds of carbon (C) and hydrogen (H) in which the carbon atoms have linear, branched chain (open), or both types of structures. Aliphatics, as they are informally called, can be divided into paraffinic (saturated) and olefinic (unsaturated) chain types. The simplest aliphatic, paraffinic hydrocarbon is?methane, CH4. The simplest aliphatic, olefinic hydrocarbon?is ethylene, C2H6. In drilling fluids, particularly oil-base muds, the amounts and types of hydrocarbon in the?mud?can be an important parameter in overall performance of the mud. Syn: Acyclic Compound.
