Structure of oil-water contact zones of Bashkirian carbonate reservoirs

Abstract

The authors have shown principle structure of oil-water contact zones in Bashkirian carbonate reservoirs of Volga-Ural region. There were established structural and mineral characteristics of oil-water contact zones and were shown main regularities of changing composition of hydrocarbons along the section. It depends from type, speed and intensity of metasomatic transformations of rocks.
