The Effect of EOR Technologies on the Content of Petroporphyrins and Naphthenic Acids of Recovered Heavy Oils from Usinskoye Field

Abstract:

The effect of EOR technologies on the contents of petroporphyrins and naphthenic acids in recovered crude oil was studied using heavy oil from Usinskoye oil field (Republic Komi), which has high density, high content nickel and vanadium porphyrin complexes, the oxygen compounds and naphthenic acids. It is found that EOR system in combination with thermal steam treatment injection brings about an increase in the content of vanadium porphyrin complexes of crude oils. As a result of the oil-displacement EOR system injection, the naphthenic acids content would decrease in heavy oils.
