Sallie2 #15 (API 42-135-40093) is a well in Ector County operated by Diamondback E&P LLC, completed January 25, 2011 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued December 16, 2009, permitted to 10,150 ft.

It was permitted by Cog Operating LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.

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

Its lease has reported 720K barrels of oil and 2.17M mcf of gas since December 2007, last reporting in July 2026. The lease carries 15 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.
