Best-practice stochastic facies modelling from a channel fill turbidite sandstone analog (the 'Quarry outcrop', Eocene Ainsa Basin, NE Spain)

Using data from an outcrop characterization of a sandstone-rich turbidite channel fill (the so-called ‘‘Quarry outcrop’’ in the Ainsa basin), several stochastic facies models were constructed at bedscale resolution (cells 2.5 m [8 ft] wide and 0.05 m [2 in.] thick).</p><p>Several industr...
