Lithogenetic classification of carbonate reservoirs using well log-data for more precise definition of reservoir properties

Authors: O.A. Botvinovskaya, D.I. Ganichev, A.A. Tveritnev (Rosneft Oil Company OJSC), V.A. Bogoslovsky, B.A. Nikulin (Lomonosov Moscow State University)
A method of lithogeneous rock typification and clarification for improved reservoir properties determination from log data is presented. On the example of the Lower Devonian carbonate formations of the Timan-Pechora region we show the application of certain mathematical data classification methods for the training set, which allowed to justify a logging suite for facial zone identification. Construction of regression models enabled a lithogeneous typification of geological sections with an acceptable accuracy.
