Wintermann #7 (API 42-481-34563) is a well in Wharton County operated by Proline Energy Resources Inc, completed August 14, 2004 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued August 20, 2003, permitted to 12,755 ft.
It was permitted by Pogo Producing CO. and has since transferred to Proline Energy Resources Inc on the wellbore schedule.
Completion filings report 4 formation tops, including Top Of Vickburg, Vicksburg, Yegua, Wilcox.
Its 2 leases have reported 26.5K barrels of oil and 904K mcf of gas since November 2003, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Mar 15, 2007. Gamma ray, 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.
