Cravens 35 A #1 (API 42-227-36713) is a well in Howard County operated by Oxyrock Operating LLC, completed December 2, 2011 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued August 5, 2011, permitted to 10,453 ft.

It was permitted by Crownquest Operating, LLC and has since transferred to Oxyrock Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Spraberry, Strawn, Atoka, Mississippian.

Its lease has reported 231K barrels of oil and 862K mcf of gas since December 2011, last reporting volume in April 2026. The lease carries 5 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.

1 log loaded from the RRC's log index, the latest received Oct 10, 2014. 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.
