La Salle County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Zizinia #18H (API 42-283-34426) is a horizontal well in La Salle County operated by Crescent Energy Operating LLC, completed May 20, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 9, 2013, permitted to 8,455 ft.
It was permitted by Cheyenne Petroleum Company and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Wilcox, Escondido, Olmos, Austin Chalk.
Its lease has reported 3.49M barrels of oil and 4.6M mcf of gas since April 2012, last reporting volume in April 2026. The lease carries 22 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Feb 27, 2017. 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.
