Howard County · Moore field · Producing · Vertical
Welsh Katherine #12 (API 42-227-33745) is a well in Howard County operated by Free Rein Operating LLC, completed August 29, 1985 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued May 13, 1985, permitted to 3,600 ft.
It was permitted by Peregrine Petr. Of Houston, Inc. and has since transferred to Free Rein Operating LLC on the wellbore schedule.
Its lease has reported 76K barrels of oil and 3.24K mcf of gas since January 1993, last reporting in July 2026. The lease carries 14 wells, so these are lease totals, not this well alone.
