Kuykendall Ranch #1H (API 42-311-35030) is a horizontal well in Mcmullen County operated by Crescent Energy Operating LLC, completed December 8, 2012 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 17, 2012, permitted to 10,695 ft.
It was permitted by Marathon Oil EF LLC and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.
Its lease has reported 285K barrels of oil and 602K mcf of gas since December 2012, last reporting volume in April 2026. The lease carries 4 wells, so these are lease totals, not this well alone.

Well logs
3 logs loaded from the RRC's log index, the latest received Oct 13, 2015. Density, Neutron, 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.
