Outcrops of the Miocene-Pliocene Capistrano Formation at San Clemente, California, provide an excellent exposure of sandy slope channel fills that are cut into the strongly bioturbated muddy slope of the Miocene Monterey Formation. Since1998 we have focused on the sedimentology and depositional model for this widely-used slope channel system analogue. Currently, Pan Li (PhD student) is investigating the internal channel architecture, geometries and facies distribution of the channel fills at San Clemente. The primary aim of his study is trying to better understand this slope channel system with special attention to its facies and associated reservoir architecture. The results will be used as constraints for reservoir characterization in comparable slope channels in the subsurface.
