Bigtooth Maple D #8AA (API 42-317-42321) is a horizontal well in Martin County operated by Oxyrock Operating LLC, completed March 5, 2020 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued May 28, 2019, permitted to 10,300 ft.

It was permitted by Crownquest Operating, LLC and has since transferred to Oxyrock Operating LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Yates, Grayburg, San Andres, Spraberry.

Its lease has reported 572K barrels of oil and 3.18M mcf of gas since March 2020, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
