Tobosa D #6AA (API 42-227-39693) is a horizontal well in Howard County operated by Oxyrock Operating LLC, completed October 6, 2019 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued July 17, 2018, permitted to 10,000 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, San Andres, Glorieta, Clear Fork.

Its lease has reported 808K barrels of oil and 1.88M mcf of gas since October 2019, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
