Upton County · Spraberry (Trend Area) field · Shut IN · Vertical
Dorcus #8 (API 42-461-38192) is a well in Upton County operated by Firebird Energy II LLC, completed February 23, 2023 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued July 17, 2012, permitted to 12,000 ft.
It was permitted by Cog Operating LLC and has since transferred to Firebird Energy II LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Wolfcamp, Bend.
Its lease has reported 500K barrels of oil and 4.01M mcf of gas since September 2011, last reporting in July 2026. The lease carries 11 wells, so these are lease totals, not this well alone.
