WELL · 42-059-35824 · DISTRICT 7
Mask #10
Callahan County · Callahan County Regular field · Vertical
Mask #10 (API 42-059-35824) is a well in Callahan County operated by Rg1 Energy LLC, completed December 4, 1987.
The RRC has issued one drilling permit, issued November 13, 1987, permitted to 600 ft.
It was permitted by Brown, Michael D. and has since transferred to Rg1 Energy LLC on the wellbore schedule.
Its 3 leases have reported 5.06K barrels of oil and 130 mcf of gas since January 1993, last reporting in July 2026. The leases carry 25 wells, so these are lease totals, not this well alone.
