Orsborn Unit #21 (API 42-269-31306) is a plugged well in King County, plugged November 11, 2021, last operated by Great American Resources Inc..

The RRC has issued one drilling permit, issued August 21, 1984, permitted to 5,270 ft.

It was permitted by Conoco Inc. and has since transferred to Great American Resources Inc. on the wellbore schedule.

Completion filings report 4 formation tops, including Coleman Junction, Cisco, Strawn, Katz.

Its 2 leases have reported 191K barrels of oil and 19.8K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 48 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.
