Ring reduction via natural anaerobic microbiological activity for transformation of crude oil-associated aromatic chemicals

摘要

Methods of reducing the viscosity of crude oil in an oil well are provided. The methods comprise the introduction of at least on reductant to an injection fluid which is then injected into the well. Aromatic hydrocarbons in the oil are reduced in the presence of reductant and indigenous microbial populations to reduce the viscosity of the oil.
