Klein-Sanchez #2 (API 42-283-31323) is a plugged horizontal well in La Salle County, plugged December 13, 2004, last operated by Cox & Cox Production CO..
The RRC has issued one drilling permit, issued May 23, 1990, permitted to 9,800 ft.
It was permitted by Wainoco Oil & Gas Company and has since transferred to Cox & Cox Production CO. on the wellbore schedule.
Completion filings report one formation top, including Austin Chalk.
Its lease has reported 2.43K barrels of oil and 2.18K 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 Wainoco Oil & Gas Company; the EWA schedule now lists a different operator.
