This should be a good "at a glance" indicator of the relative ratio of carbonates vs clastics within the underlying Rogersville in relation to unconventional completions as well as the potential for high quality sands in the Rome below and the Maryville directly above to have received direct and or substantial hydrocarbon charge from migration out of the self-sourcing Rogersville shale.

Sandstone percentages are derived from lithologic fractions calculated by
computer from digital well log data. The quality of these data are dependent
on the original log quality and the accuracy of the lithology calculation. For
these maps, rocks were classified as sandstone if the sandstone component
calculated was greater than or equal to 40%. Well locations indicated with
a + symbol are partial penetrations, and these values are not necessarily
honored by the contours.

At A Glance Insights Into The Composition of the Rogersville shale.

New Rogersville Shale well locations and opportunities within the Rome Trough of Eastern Kentucky including the Exxon Smith #1
well, the location of the highest documented Rogersville TOC and the preferred migration pathway suggested by Ryder in Open-File
Report 05-1443.

Highlighting the differences in make up of the Maryville Limestone (Plate 21 transparency) which directly overlies the Rogersville
Shale overlain on base map showing the high porosity Rome Net Sands (plate 23-B) that are below the Rogersville shale
hydrocarbon kitchen. .Modified from Plates 23-B and 21 of the Rome Trough Consortium Study by Harris and Others.

Far right shows comparison between the gamma logs from the EQT-Horizontal Technologies 1-H and the Ashland Williams #1 well
the EQT log is marked MD and without a TVD or directional survey it is hard to tell but the survey tells us it is vertical. Terminology
issues between the different O&G companies is obvious in the comparison of log signatures compared to the drillers Logs.
