Armstrong Elizabeth -E- #8 (API 42-003-36438) is a well in Andrews County operated by Coda Energy Inc., completed September 28, 1990.

The RRC has issued 2 drilling permits between 1989 and 1990, permitted to 9,500 ft.

It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Coda Energy Inc. on the wellbore schedule.

Completion filings report 3 formation tops, including Wolcamp, Wolfcamp, Pennsylvanian.

Its 4 leases have reported 9.42M barrels of oil and 8.39M mcf of gas since January 1993, last reporting in July 2026. The leases carry 106 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 45.8K barrels injected in the 12 months reported through February 2026.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
