Gregory Margaret Unit #1RE (API 42-287-31054) is a horizontal well in Lee County operated by Magnolia Oil & Gas Operating LLC, completed March 26, 1998 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits between 1981 and 1998, permitted to 9,928 ft.

It was permitted by Browning Oil Company, Inc. 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 182K barrels of oil and 414K 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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
