Appel 438 #1 (API 42-295-32992) is a well in Lipscomb County operated by Highmark Energy Operating LLC, completed April 28, 2011 and listed as shut in on the RRC schedule, shut in July 1, 2023.

The RRC has issued 2 drilling permits (amended twice) between 2006 and 2011, permitted to 10,150 ft.

It was permitted by Eog Resources, Inc. and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.

Completion filings report 9 formation tops, including Bhbr, Tonkawa, Cottage Grove, Checkerboard.

Its 3 leases have reported 2.89K barrels of oil and 164K mcf of gas since May 2006, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.

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