USGS on Smackover, Norphlet, etc.

I meant to post this a while back, but here is a link to the U.S. Geological Survey document "Assessment of Undiscovered Oil and Gas Resources in Jurassic and Cretaceous Strata of the Gulf Coast, 2010," which was released earlier this month.  The report attempts to quantify undiscovered oil, gas and NGLs in the three USGS defined provinces along the Gulf Coast.  In the report is an assessment of the various "assessment units" of the Haynesville and Bossier as well as the Smackover and Norphlet formations.

The report is fairly simplified, but to a regular old yutz like me who likes pretty pictures over long tables, it had a generalized stratigraphic section of the region to help keep all of the various formations straight.  It's interesting to see that the Smackover and Norphlet are only 5-10 million  years older than the Haynesville.  Not long in geologic time.
