Influence of reservoir heterogeneity characteristics on ultimate oil recovery in Priobskoye field

Authors: A.V. Timonov, A.V. Sergejchev, I.R. Yamalov, T.R. Musabirov (Rosneft Oil Company OJSC, RF, Moscow)

Key words: reservoir heterogeneity, connectivity, waterflooding performance, recovery factor.

Influence of reservoir characterization parameters variation to the development efficiency for Priobskoye oil field is considered. Waterflooding performance is analyzed for different parts of the field and predicted values of recovery factor are estimated. Empirical correlations of recovery factor depending on well density and reservoir characteristics describing vertical and lateral reservoir heterogeneity are determined.
