Lipscomb County · Lipscomb (Cleveland) field · Shut IN  · Horizontal

Cooper 445 #1H (API 42-295-33306) is a horizontal well in Lipscomb County operated by Highmark Energy Operating LLC, completed June 4, 2008 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued March 13, 2008, permitted to 9,000 ft.

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

Completion filings report 2 formation tops, including Checkerboard Limestone, Cleveland.

Its lease has reported 241K barrels of oil and 2.37M mcf of gas since June 2008, last reporting in July 2026. The lease carries 4 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.
