Briscoe-Mcknight #8986H (API 42-127-38415) is a horizontal well in Dimmit County operated by Magnolia Oil & Gas Operating LLC, completed October 21, 2021 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued September 8, 2021, permitted to 5,700 ft.

It was permitted by El Toro Resources LLC and has since transferred to Magnolia Oil & Gas Operating LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Escondido, Olmos, San Miguel, Anacacho.

Its lease has reported 556K barrels of oil and 418K mcf of gas since September 2017, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
