Frio County · Pearsall (Austin Chalk) field · Vertical
Chiodo V.R. C #1 (API 42-163-31550) is a plugged well in Frio County, plugged August 20, 1992, last operated by Wcs Oil And Gas Corporation.
The RRC has issued one drilling permit, issued November 21, 1977, permitted to 7,250 ft.
It was permitted by Dilley Production CO. and has since transferred to Wcs Oil And Gas Corporation on the wellbore schedule.
Its 2 leases have reported 1.73K barrels of oil and 3 mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
