Howard County · Moore field · Producing · Vertical
Rosser #1 (API 42-227-33866) is a well in Howard County operated by Free Rein Operating LLC, completed December 30, 1985 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 7, 1985, permitted to 3,600 ft.
It was permitted by Enduro Oil Company Inc. and has since transferred to Free Rein Operating LLC on the wellbore schedule.
Its lease has reported 24.1K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Enduro Oil Company Inc.; the EWA schedule now lists a different operator.
