n: a substance that consists of large rnolecules formed frorn srnaller rnolecules in repeating structural units (rnonomers). In oilfield operations, various types of polymers are used to thicken drilling rnud, frac- turing fluid, acid, water, and other liquids. See micellar-polymer flooding, polymer mud. In petroleum refining, heat and pressure are used to polyrnerize light hydrocarbons into larger rnolecules, such as those that rnake up high-octane gasoline. In petrochernical production, polymer hydrocarbons are used as a feedstock for plastics.

a synthetic or man made gelling agent that increases viscosity and helps control leakoff.
