The RRC has issued 2 drilling permits (amended twice) between 1981 and 1990, permitted to 8,600 ft.
It was permitted by Sanchez-O'Brien / Texaco Inc. and has since transferred to Drexel Operating Company on the wellbore schedule.
Completion filings report 2 formation tops, including Anacacho, Austin Chalk.
Its lease has reported 63.1K barrels of oil and 3.25K 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.
