Roadrunner-Knox Unit #1 (API 42-287-31686) is a well in Lee County operated by Anchor Operating CO., completed December 14, 1984.
The RRC has issued one drilling permit, issued August 10, 1984, permitted to 9,500 ft.
It was permitted by Santa FE Minerals, Inc. and has since transferred to Anchor Operating CO. on the wellbore schedule.
Completion filings report 4 formation tops, including Navarro, Pecan Gap, Austin Chalk, Eagle Ford.
Its 2 leases have reported 26.9K barrels of oil and 330K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
