Barbee #4A (API 42-173-35394) is a well in Glasscock County operated by Discovery Natural Resources LLC, completed May 9, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued October 26, 2012, permitted to 9,392 ft.

It was permitted by Fiml Natural Resources, LLC and has since transferred to Discovery Natural Resources LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Spraberry, Dean, Wolfcamp, Canyon.

Its lease has reported 793K barrels of oil and 6.35M mcf of gas since August 2011, last reporting in July 2026. The lease carries 27 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.
