Duval Ranch Sec. 101 #8 (API 42-131-37205) is a plugged well in Duval County, plugged March 31, 2022, last operated by Killam Oil CO. Ltd..
The RRC has issued one drilling permit, issued April 5, 1989, permitted to 2,500 ft.
It was permitted by Man-Gas Transmission Company and has since transferred to Killam Oil CO. Ltd. on the wellbore schedule.
Completion filings report one formation top, including Chernosky.
Its lease has reported 8.58K barrels of oil and 21 mcf of gas since January 1993, last reporting in June 2022. The lease carries 3 wells, so these are lease totals, not this well alone.
