    Lithofacies Classification in the Marcellus Shale by Applying a Statistical Clustering Algorithm to Petrophysical and Elastic Well Logs.Kristen Schlanser, Dario Grana & Erin Campbell-Stone - 2016 - Interpretation: SEG 4 (2):SE31-SE49.
    Interpreting shale lithofacies is an important step in identifying productive zones in the Marcellus Shale gas play; the target reservoir can be less than 3 m thick with overlying shales that appear similar on certain petrophysical well logs and in the core. However, these nonreservoir-quality shales contain widely varying organic and mechanical properties. To distinguish between reservoir- and nonreservoir-quality shale facies, this classification method applies a pattern-recognition algorithm, expectation maximization, to a set of commonly available petrophysical and elastic well logs (...)

    Petroelastic and Geomechanical Classification of Lithologic Facies in the Marcellus Shale.Dario Grana, Kristen Schlanser & Erin Campbell-Stone - 2015 - Interpretation: SEG 3 (1):SA51-SA63.
    Log-facies classification at the well location allows determination of the number of facies, the facies definition, and the correlation between facies and rock properties along the well profile. In unconventional reservoirs, because of the necessity for hydraulic fracturing in shale gas and shale oil reservoirs, facies classification should account for petroelastic and geomechanical properties. We developed a facies classification methodology based on the expectation-maximization algorithm, a statistical method that allows finding the most likely facies classification and the associated probability distribution, (...)
