Rfr Frio 15 GU #139 (API 42-071-02891) is a well in Chambers County operated by Masters Resources L.L.C., completed December 10, 1977.
The RRC has issued one drilling permit, issued October 31, 1977, permitted to 12,650 ft.
It was permitted by Exxon Corp. and has since transferred to Masters Resources L.L.C. on the wellbore schedule.
Its 2 leases have reported 68.2K barrels of oil and 585K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
