Mitchell J #1
Marion County · Lassater (Travis Peak Gas) field · Vertical
Mitchell J #1 (API 42-315-30604) is a well in Marion County operated by Marathon Oil Company, completed August 14, 1983.
The RRC has issued 2 drilling permits between 1982 and 2016, permitted to 9,500 ft.
It was permitted by Buffco Production Inc. and has since transferred to Marathon Oil Company on the wellbore schedule.
Completion filings report 4 formation tops, including Base Mass. Anhyd., B. Mass Anhyd, Pettit, Travis Peak.
Its 2 leases have reported 139K barrels of oil and 165K 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.
