Heard Bower Central Unit #24H (API 42-013-34898) is a horizontal well in Atascosa County operated by Marathon Oil EF LLC, completed February 19, 2023 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 6, 2014, permitted to 11,100 ft.

It was permitted by Aurora USA Development, LLC and has since transferred to Marathon Oil EF LLC on the wellbore schedule.

Completion filings report 13 formation tops, including Queen City, Reklaw, Carrizo, Wilcox.

Its lease has reported 998K barrels of oil and 1.36M mcf of gas since September 2011, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
