Shiner Ranch #3
Frio County · Pearsall (Austin Chalk) field · Horizontal
Shiner Ranch #3 (API 42-163-33071) is a plugged horizontal well in Frio County, plugged February 21, 2024, last operated by Trinity Operating (Usg) LLC.
The RRC has issued one drilling permit, issued May 29, 1991, permitted to 12,100 ft.
It was permitted by Oryx Energy Company and has since transferred to Trinity Operating (Usg) LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Wilcox, San Miguel, 1st Lime, Anacacho.
Its lease has reported 634K barrels of oil and 1.22M mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 13 wells, so these are lease totals, not this well alone.
