Thornton Bertie Trust #1 (API 42-441-33459) is a plugged well in Taylor County, plugged October 2, 2018, last operated by Graystone Energy Corporation.

The RRC has issued one drilling permit, issued September 13, 1990, permitted to 1,995 ft.

It was permitted by Kapitan Energy, Inc. and has since transferred to Graystone Energy Corporation on the wellbore schedule.

Completion filings report 3 formation tops, including Saddle Creek, Flippen Lime, Cook Sand.

Its lease has reported 36.1K barrels of oil and 57 mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
