Chargos Creek A #1 (API 42-505-36467) is a plugged well in Zapata County, plugged January 21, 2019, last operated by Zapata Oil Partners L.L.C..
The RRC has issued one drilling permit, issued November 6, 2009, permitted to 1,700 ft.
It was permitted by Ridgeline Energy Inc. and has since transferred to Zapata Oil Partners L.L.C. on the wellbore schedule.
Completion filings report one formation top, including Mirando.
Its lease has reported 6.02K barrels of oil since February 2010, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Ridgeline Energy Inc.; the EWA schedule now lists a different operator.
