Armstrong, C. M. #23D

Armstrong, C. M. #23D (API 42-261-00439) is a former disposal or injection well in Kenedy County, last operated by Exxon Mobil Corporation; its UIC permit is no longer active.

The RRC has issued 6 drilling permits between 1978 and 2001, permitted to 9,765 ft.

Its 3 leases have reported 22.5K barrels of oil and 60.8K mcf of gas since January 1993, last reporting in November 2004. The leases carry 6 wells, so these are lease totals, not this well alone.
