Conclusions Sequence architecture of the Pocahontas basin exhibits broad, regional flooding surfaces and discontinuities in the subsurface Integration of core and outcrop measurements with geophysical well log data aids sequence model verification Sequence model identifies regional CO 2 storage and sealing lithologies for targeted sequestration opportunities Continued work will focus on the interplay of eustatic and tectonic controls on basin infilling
