Zizinia #4H (API 42-283-33357) is a horizontal well in La Salle County operated by Crescent Energy Operating LLC, completed October 29, 2023 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued July 2, 2012, permitted to 8,447 ft.

It was permitted by Cheyenne Petroleum Company and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Olmos, Austin Chalk, Eagle Ford.

Its lease has reported 3.52M barrels of oil and 4.62M mcf of gas since April 2012, last reporting volume in August 2026. The lease carries 22 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
