Klopek #4
Frio County · Pearsall (Austin Chalk) field · Horizontal
Klopek #4 (API 42-163-32893) is a plugged horizontal well in Frio County, plugged April 30, 2001, last operated by Vac-U-Lift Production CO. Inc..
The RRC has issued one drilling permit (amended once), issued October 23, 1990, permitted to 7,500 ft.
It was permitted by Durst Oil Company and has since transferred to Vac-U-Lift Production CO. Inc. on the wellbore schedule.
Completion filings report one formation top, including Austin Chalk.
Its lease has reported 4.1K barrels of oil and 2.38K 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.
