Hayden #1 (API 42-461-34163) is a plugged well in Upton County, plugged November 16, 2023, last operated by Cog Operating LLC.

The RRC has issued one drilling permit, issued March 26, 2001, permitted to 9,700 ft.

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

Completion filings report 4 formation tops, including Leonard, Wolfcamp, Dean, M. Wolfcamp.

Its 3 leases have reported 190K barrels of oil and 521K mcf of gas since May 2001, with no volume in the three years through April 2026. The leases carry 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.
