Marshall #1 (API 42-503-39320) is a well in Young County operated by Oakmont Oil And Gas, completed October 21, 1986 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued August 22, 1986, permitted to 4,999 ft.
It was permitted by Three P Operating Company and has since transferred to Oakmont Oil And Gas on the wellbore schedule.
Completion filings report 3 formation tops, including Taylor, Caddo, Marble Falls.
Its lease has reported 152K barrels of oil and 9 mcf of gas since January 1993, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 12.8K barrels injected in the 12 months reported through November 2025.
