Barbee #4Y (API 42-173-35392) is a well in Glasscock County operated by Discovery Natural Resources LLC, completed June 1, 2013 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued November 27, 2012, permitted to 10,500 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.
