Armstrong L. P. #1 (API 42-049-32077) is a plugged well in Brown County, plugged December 13, 1996, last operated by Cpmak Investments Inc..
The RRC has issued 2 drilling permits between 1979 and 1983, permitted to 3,184 ft.
It was permitted by Cassell Oil CO. and has since transferred to Cpmak Investments Inc. on the wellbore schedule.
Completion filings report one formation top, including Cross Cut.
Its lease has reported 6.4K barrels of oil and 5 mcf of gas since January 1993, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
