Irvin #8H (API 42-283-33398) is a horizontal well in La Salle County operated by Crescent Energy Operating LLC, completed April 5, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued July 24, 2012, permitted to 8,588 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 2.53M barrels of oil and 2.7M mcf of gas since January 2012, last reporting volume in April 2026. The lease carries 17 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.

Well logs

1 log loaded from the RRC's log index, the latest received Oct 16, 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.
