Harris #4 (API 42-163-32691) is a plugged horizontal well in Frio County, plugged October 24, 2025, last operated by Rio-Tex Inc..
The RRC has issued one drilling permit (amended once), issued April 5, 1990, permitted to 7,300 ft.
It was permitted by Dale Operating Company and has since transferred to Rio-Tex Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Olmos, San Miguel, Austin Chalk.
Its 2 leases have reported 53K barrels of oil and 10.2K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
