Harris County · Goose Creek field · Vertical
Hirsch State #21 (API 42-201-31934) is a plugged well in Harris County, plugged April 1, 2026, last operated by Gaither Petroleum Corporation.
The RRC has issued one drilling permit, issued May 3, 1985, permitted to 2,850 ft.
It was permitted by Gulf Oil Corp. and has since transferred to Gaither Petroleum Corporation on the wellbore schedule.
Completion filings report one formation top, including Miocene (undifferentiated).
Its lease has reported 154K barrels of oil and 9.87K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
