Cvx 1 #12 (API 42-135-40358) is a well in Ector County operated by Crescent Energy Operating LLC, completed September 25, 2024 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 2010 and 2013, permitted to 6,080 ft.
It was permitted by Sheridan Production Company, LLC and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Yates, Queen, Grayburg, San Andres.
Its lease has reported 614K barrels of oil and 1M mcf of gas since September 2008, 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 Aug 2, 2013. Density, Neutron. 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.
