D. Jost Oil Unit #15R (API 42-383-38689) is a well in Reagan County operated by Crescent Energy Operating LLC, completed September 13, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued April 21, 2014, permitted to 10,305 ft.

It was permitted by Laredo Petroleum, Inc. and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Completion filings report 8 formation tops, including Grayburg, San Andres, Clear Fork, Spraberry.

Its lease has reported 159K barrels of oil and 1.16M mcf of gas since January 2011, last reporting volume in July 2026. The lease carries 3 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 Jul 25, 2017. 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.
