Anderson County · Concord Dome (Rodessa) field · Directional
Marks #1ST (API 42-001-32357) is a well in Anderson County operated by Permian Natural Resources, completed October 8, 2004.
The RRC has issued 2 drilling permits (amended twice) between 2001 and 2004, permitted to 14,000 ft.
It was permitted by J-W Operating CO. and has since transferred to Permian Natural Resources on the wellbore schedule.
Completion filings report 4 formation tops, including Woodbine, Base Of Salt, Glen Rose, James Lime.
Its 2 leases have reported 279 barrels of oil and 688K mcf of gas since July 2001, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by J-W Operating Co.; the EWA schedule now lists a different operator.
