Reagan County · Spraberry (Trend Area) field · Producing · Vertical
Siler #4 (API 42-383-34359) is a well in Reagan County operated by Diamondback E&P LLC, completed March 29, 1995 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued March 14, 1995, permitted to 8,250 ft.
It was permitted by Stephens, Autry C. 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 77.6K barrels of oil and 1.02M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
