Petrophysical Evaluation in the Countries of the Former Soviet Union

by Alan Sibbit, Schlumberger

Abstract

Many Western trained petrophysicists have the impression that the interpretation of Russian logs requires arcane and specialized skills. Whereas familiarity with the Russian (Cyrillic) alphabet, a glossary of terms and access to the correct environmental correction algorithms are required – Russian interpretation methods are very practical and accessible. We briefly review the traditional methods of data acquisition in the various basins of the former Soviet Union and discuss interpretation methods.
