Sallie B #1203 (API 42-135-39736) is a well in Ector County operated by Diamondback E&P LLC, completed March 13, 2010 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued November 18, 2008, permitted to 10,800 ft.

It was permitted by Henry Petroleum LP and has since transferred to Diamondback E&P LLC on the wellbore schedule.

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

Its lease has reported 1.03M barrels of oil and 2.7M mcf of gas since October 2005, last reporting in July 2026. The lease carries 17 wells, so these are lease totals, not this well alone.
