Hardin Unit #A 1H (API 42-163-33520) is a horizontal well in Frio County operated by Callon (Eagle Ford) LLC, completed January 7, 2012.
The RRC has issued one drilling permit, issued September 12, 2011, permitted to 9,000 ft.
It was permitted by Zaza Energy, LLC and has since transferred to Callon (Eagle Ford) LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Austin Chalk, Lower Chalk, Eagle Ford.
Its 2 leases have reported 128K barrels of oil and 381K mcf of gas since January 2012, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
