Neches -15a- #4 (API 42-173-35500) is a well in Glasscock County operated by Black Swan Opco LLC, completed June 28, 2013 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued December 19, 2012, permitted to 11,000 ft.

It was permitted by Energen Resources Corporation and has since transferred to Black Swan Opco LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Spraberry, Wolfcamp, Strawn.

Its lease has reported 160K barrels of oil and 424K mcf of gas since March 2012, last reporting in July 2026. The lease carries 4 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.
