Slover-Beever Unit #1
Frio County · Pearsall (Austin Chalk) field · Horizontal · Sidetrack
Slover-Beever Unit #1 (API 42-163-31798) is a plugged horizontal well in Frio County, plugged April 26, 2006, last operated by D. And Y. Yunk Productions.
The RRC has issued 2 drilling permits (amended once) between 1980 and 1991, permitted to 6,500 ft.
It was permitted by Hartford Exploration, Inc. and has since transferred to D. And Y. Yunk Productions on the wellbore schedule.
Completion filings report one formation top, including Austin Chalk.
Its lease has reported 4.59K barrels of oil and 19 mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Hartford Exploration, Inc.; the EWA schedule now lists a different operator.
