re: Tell me about the Tuscaloosa Marine Shale deposit in Louisiana.

That's correct also. I was trying to keep it simple. Plus some formations are different in different states like hosston in louisiana and Travis peak in texas. Haynesville is a little different in that the formation near Haynesville is sand. The shale play itself is probably lower Bossier but mclendon wanted a new name to distinguish it as a Chesapeake discovery.
