Matagorda County · Palacios (Frio -E-) field · Vertical
Carlson Richard #1 (API 42-321-01936) is a plugged well in Matagorda County, plugged July 22, 1998, last operated by Unit Petroleum Company.
The RRC has issued one drilling permit, issued March 15, 1996, permitted to 8,850 ft.
It was permitted by Shana Petroleum Company and has since transferred to Unit Petroleum Company on the wellbore schedule.
Its 2 leases have reported 1 barrels of oil and 13.4K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
