Sallie E #4804 (API 42-135-39930) is a well in Ector County operated by Diamondback E&P LLC, completed February 19, 2010 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued August 28, 2009, permitted to 10,122 ft.

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

Completion filings report 4 formation tops, including Spraberry, Dean, Wolfcamp, Base Big Lime.

Its lease has reported 150K barrels of oil and 205K mcf of gas since February 2008, last reporting in July 2026. The lease carries 3 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.
