Erna H. #1RE (API 42-287-31368) is a horizontal well in Lee County operated by Magnolia Oil & Gas Operating LLC, completed March 22, 1994.

The RRC has issued 4 drilling permits (amended once) between 1983 and 2012, permitted to 12,000 ft.

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

Completion filings report 3 formation tops, including Pecan Gap, Austin Chalk, Eagle Ford.

Its lease has reported 272K barrels of oil and 804K 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.
