Leggio-Schubert #1RE
Burleson County · Caldwell (Austin Chalk) field · Horizontal · Sidetrack
Leggio-Schubert #1RE (API 42-051-31207) is a horizontal well in Burleson County operated by Proline Energy Resources Inc, completed January 10, 1981.
The RRC has issued 2 drilling permits (amended once) between 1980 and 1999, permitted to 9,000 ft.
It was permitted by Cox & Perkins Exploration, Inc. and has since transferred to Proline Energy Resources Inc on the wellbore schedule.
Completion filings report one formation top, including Austin Chalk.
Its 2 leases have reported 146K barrels of oil and 1.54M mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
