Orsborn #27 (API 42-269-31394) is a plugged well in King County, plugged November 23, 2010, last operated by Apache Corporation.
The RRC has issued one drilling permit, issued January 15, 1985, permitted to 5,280 ft.
It was permitted by Conoco Inc. and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 2 formation tops, including Katz, Katz (5100).
Its 2 leases have reported 163K barrels of oil and 22.8K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 28 wells, so these are lease totals, not this well alone.
