Shiner Ranch #7 (API 42-163-33106) is a horizontal well in Frio County operated by Trinity Operating (Usg) LLC, completed July 17, 1993 and listed as injection on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 1991 and 1993, permitted to 7,650 ft.
It was permitted by Oryx Energy Company and has since transferred to Trinity Operating (Usg) LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Midway, Olmos, San Miguel, Anacacho.
Its lease has reported 634K barrels of oil and 1.22M mcf of gas since January 1993, last reporting in July 2026. The lease carries 13 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 38.2K barrels injected in the 12 months reported through February 2026.
