Rousselot Doris Mayer A #16 (API 42-413-32541) is a well in Schleicher County operated by Upp Operating LLC, completed September 17, 2008 and listed as swr-10-well on the RRC schedule, shut in October 1, 2013.
The RRC has issued one drilling permit, issued August 11, 2008, permitted to 8,110 ft.
It was permitted by Highmount Expl & Prod Texas LLC and has since transferred to Upp Operating LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Base Cretaceous (marker), Wolfcamp, Canyon, Strawn.
Its 2 leases have reported 32 barrels of oil and 17.7K mcf of gas since September 2008, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Oct 3, 2011. Density, Neutron, Resistivity. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
