Orsborn Unit #32 (API 42-275-31777) is a plugged well in Knox County, plugged October 5, 2006, last operated by Apache Corporation.
The RRC has issued one drilling permit, issued September 12, 1986, permitted to 5,200 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 Strawn, 5100 Strawn.
Its lease has reported 169K barrels of oil and 19.8K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 29 wells, so these are lease totals, not this well alone.
