From Well Logs to Stratigraphic Layering: Automation, Uncertainties and Impact on Reservoir Behavior

Computer-assisted stochastic multi-well correlation: Sedimentary facies versus well distality

“…Additional data or concepts could also be integrated in the method, preferably as cost function to be combined to the proposed correlation cost function, as an ancillary geological likelihood data to evaluate the results (e.g., de la Varga and Wellmann, 2016). Posterior analysis on the generated stratigraphic model may be achieved to evaluate the physical likelihood of the correlation outcomes (layer connectivities) like hydraulic or tracer simulation tests (e.g., Baville et al, 2019). Another way to scrutinize and improve the results could be to analyze the geometry of the chronostratigraphic units and their consistency with dipmeter data and subsidence analysis.…”
