Preparation of Well-logging Data before Seismic Inversion Application

The article is devoted to well-logging data preparation before seismic inversion is applied. The essential impact of raw well-logging data (sonic and density logs) on reservoir properties prediction accuracy is demonstrated. The main factors that have the influence on the input data quality are appointed. On the one of the example of gas field located in the Ukrainian part of the Black Sea the results of specialized techniques for well-logging data quality improving are shown.
