Hirsch #4 (API 42-479-34353) is a plugged well in Webb County, plugged June 10, 2011, last operated by Conocophillips Company.
The RRC has issued one drilling permit, issued March 27, 1986, permitted to 11,500 ft.
It was permitted by Transamerican Natural Gas Corp. and has since transferred to Conocophillips Company on the wellbore schedule.
Completion filings report 5 formation tops, including Yegua, Queen City, Wilcox, Willis Point.
Its 2 leases have reported 18 barrels of oil and 49.2K mcf of gas since the record begins in January 1993, with no volume in the three years through August 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
