Halfmann T. #5 (API 42-083-34153) is a plugged well in Coleman County, plugged July 27, 2001, last operated by Round Mountain Operations.
The RRC has issued one drilling permit, issued July 25, 1984, permitted to 3,000 ft.
It was permitted by Apex Petroleum, Inc and has since transferred to Round Mountain Operations on the wellbore schedule.

Its lease has reported 4.23K barrels of oil and 57 mcf of gas since January 1993, last reporting in November 2003. The lease carries 5 wells, so these are lease totals, not this well alone.
