Midland County · Spraberry (Trend Area) field · Producing · Vertical
Alsup #1 (API 42-329-30813) is a well in Midland County operated by Diamondback E&P LLC, completed September 20, 1990 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 27, 1978, permitted to 8,840 ft.
It was permitted by Mwj Producing Company and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Its lease has reported 122K barrels of oil and 347K mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
