Steglich #4 (API 42-021-31452) is a plugged well in Bastrop County, plugged August 11, 2023, last operated by Trivista Operating LLC.
The RRC has issued one drilling permit, issued September 2, 1992, permitted to 5,700 ft.
It was permitted by San Antonio Gas & Oil, Inc. and has since transferred to Trivista Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Taylor.
Its lease has reported 70.5K barrels of oil and 100K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
