Irvin Family Unit D #2 (API 42-283-32261) is a horizontal well in La Salle County operated by Crescent Energy Operating LLC, completed October 16, 2010 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued April 19, 2010, permitted to 8,541 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 Anacacho, Eagle Ford, Buda.
Its lease has reported 49.1K barrels of oil and 176K mcf of gas since November 2010, last reporting volume in July 2025. The lease carries 2 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
2 logs loaded from the RRC's log index, the latest received Mar 5, 2014. 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.
