West Siberia Reservoir Rock Catalog

Commonwealth of Independent States

A total of 500 core plugs from fifteen (15) reservoir units in nine (9) oil fields in the southern part of western Siberia were selected to provide stratigraphic and regional coverage and analyzed to provide a database of petrophysical, petrographic, and mineralogical characteristics of major Jurassic and Cretaceous producing reservoirs.

The data presented in this study may be used to help assess reservoir quality and flow potential, identify controls on porosity and permeability, examine regional controls on reservoir quality, evaluate the potential for formation damage, correlate petrophysical data with wireline logs, and compare Russian and Western-measured porosity and permeability data.
