Riley D. #1 (API 42-317-32290) is a plugged well in Martin County, plugged April 11, 2022, last operated by Diamondback E&P LLC.
The RRC has issued 2 drilling permits between 1980 and 1993, permitted to 11,500 ft.
It was permitted by Snyder Oil Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Spraberry, Dean, Wolfcamp, Strawn.
Its 2 leases have reported 134K barrels of oil and 140K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
