Rally Petroleum #4H
Frio County · Pearsall (Austin Chalk) field · Shut IN · Horizontal
Rally Petroleum #4H (API 42-163-33441) is a horizontal well in Frio County operated by Mueller Exploration Inc., completed March 3, 2011 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued December 30, 2010, permitted to 6,942 ft.
It was permitted by U.S. Enercorp, Ltd. and has since transferred to Mueller Exploration Inc. on the wellbore schedule.
Completion filings report 2 formation tops, including Anacacho, Austin Chalk.
Its lease has reported 375K barrels of oil and 899K mcf of gas since October 2009, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
