Willis 40b #7 (API 42-329-42216) is a well in Midland County operated by Oxyrock Operating LLC, completed February 12, 2019 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 19, 2018, permitted to 12,000 ft.

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

Completion filings report 9 formation tops, including Yates, Grayburg, San Andres, Glorieta.

Its lease has reported 187K barrels of oil and 481K mcf of gas since March 2018, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
