This play will primarily be explored in Jackson and Lincoln parishes. And to a lesser extent, Claiborne and Bienville.
These wells are producing from a combination of multiple Cotton Valley Sand intervals or a combination of Cotton Valley Sands and adjacent sands of the Hosston formation (w/ Upper CV Sands) and Bossier, Haynesville or Gray Sand formations (w/ Lower CV Sands).

If anyone is interested, this USGS report on the Cotton Valley formation is an in depth study. It is in PDF format and a large file but hopefully it may be viewed.69_E_CH_2.pdf
Chester, the group name reflects the fact that the bulk of Terryville Complex wells (especially those permitted, drilled and/or completed in the last year) are not producing from a single zone or formation. If you review the True Vertical Depth (TVD) for the groups of alternate wells you will find that they stimulate a large volume of rock spread over a group of adjacent named formations. There are at least three groups of sands that are the predominate targets. All are combinations of intervals, thus the name "Combo".
Thanks for the new group, Keith. And congratulations to members with mineral interests in the Play area. In a period of few positive developments regarding the O&G industry the N-LA CV Combo Play stands out as example of what may be the next wave of major producing area that are not unconventional, not shale. The tight, liquid rich Cotton Valley Sands and the intervals that straddle the sequence in the stratagraphic column will not cover as large a continuous area as the Haynesville Shale for example but can produce really astounding results by using the latest technology and well designs from the unconventional plays.
