[54] DETERMINING OIL VISCOSITY BASED ON BIODEGRADATION
[57] Abstract: Methods, computer-readable media, and systems for determining oil viscosity based on biodegradation are described. A chemical signature of oil obtained from a subterranean zone is received. An amount of bacteria associated with oil in the zone based on the chemical signature of the oil is received. Using an empirical relationship relating oil viscosities to amounts of bacteria, an oil viscosity that is empirically related to the amount of bacteria is identified. The identified oil viscosity for the oil is provided, for example, in response to input requesting oil viscosity.
