Martin County · Spraberry (Trend Area) field · Producing  · Horizontal

Act E #05SA (API 42-317-40858) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed February 10, 2018 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued June 19, 2017, permitted to 8,900 ft.

It was permitted by Qep Energy Company and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Santa Rosa, Yates, Queen, Grayburg.

Its lease has reported 979K barrels of oil and 4.2M mcf of gas since February 2018, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
