The RRC has issued one drilling permit (amended once), issued August 21, 1987, permitted to 3,000 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Texas Petroleum Investment CO. on the wellbore schedule.
Completion filings report 2 formation tops, including Austin Chalk, Buda.
Its lease has reported 679K barrels of oil and 50 mcf of gas since January 1993, last reporting in July 2026. The lease carries 34 wells, so these are lease totals, not this well alone.
