CONCLUSIONS • Using upward shoaling and tidal-flat-capped high-frequency cycles as a basis for flow layers works well in the lower Clear Fork • High-frequency cycles are not well defined in the Wichita and flow layers are based primarily on lithology and porosity • The lower Wichita interval contains collapse breccias and flow may be dominated by touching-vug pore systems. Flow layers defined by porosity.
