Wolf-Simpson Unit #1RE (API 42-287-30902) is a horizontal well in Lee County operated by Magnolia Oil & Gas Operating LLC, completed September 11, 2009 and listed as producing on the RRC schedule.

The RRC has issued 4 drilling permits (amended twice) between 1981 and 2009, permitted to 11,162 ft.

It was permitted by Enervest Operating, L.L.C. and has since transferred to Magnolia Oil & Gas Operating LLC on the wellbore schedule.

Completion filings report one formation top, including Austin Chalk.

Its lease has reported 181K barrels of oil and 530K mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
