Thompson Unit #2 (API 42-481-31440) is a plugged well in Wharton County, plugged May 13, 2014, last operated by Frio Engineering Inc..
The RRC has issued one drilling permit, issued October 4, 1977, permitted to 5,240 ft.
It was permitted by Harkins & Company and has since transferred to Frio Engineering Inc. on the wellbore schedule.
Its 2 leases have reported 36.5K barrels of oil and 43 mcf of gas since January 1993, last reporting in September 2014. The leases carry 2 wells, so these are lease totals, not this well alone.
