a novel wireline logs based approach for assessment of

A 35‐cm diameter well bore was drilled in Decatur Illinois (3952′36 58″ N 8853′36 00″ W) from February through May of 2009 which penetrated the entire Mt Simon Sandstone section A comprehensive suite of seismic lines wireline logs full rock core and sidewall rock core were done upon completion of the well A nave approach would be to be use 'global' average values from the database for the assessment thus giving each analog reservoir the same weight in the evaluation process Our proposed methodology allows us to take into account the relative influence of each analog reservoir individually (based on some similarity measure) rather than
