Mary Ann #3 (API 42-317-35027) is a plugged well in Martin County, plugged March 27, 2025, last operated by Diamondback E&P LLC.
The RRC has issued 2 drilling permits between 2007 and 2017, permitted to 12,000 ft.
It was permitted by Qep Energy Company and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 13 formation tops, including Santa Rosa, Yates, Queen, San Andres.
Its 2 leases have reported 1.46M barrels of oil and 2.32K mcf of gas since January 1993, last reporting in June 2025. The leases carry 4 wells, so these are lease totals, not this well alone.
