Slaughter 84 #1
Martin County · Sulphur Draw (Dean 8790) field · Shut IN · Vertical
Slaughter 84 #1 (API 42-317-33270) is a well in Martin County operated by Diamondback E&P LLC, completed April 18, 2022 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued October 14, 1985, permitted to 9,400 ft.
It was permitted by Marcum Drilling CO. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report one formation top, including Dean.
Its lease has reported 81K barrels of oil and 102K 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.
