Bassi-Allison #1 (API 42-055-33418) is a well in Caldwell County operated by Petroleum Recovery Systems L.C., completed May 4, 1984 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 21, 1983, permitted to 2,800 ft.
It was permitted by Erin Southwestern Oil Inc. and has since transferred to Petroleum Recovery Systems L.C. on the wellbore schedule.
Completion filings report one formation top, including Austin Chalk.
Its lease has reported 5.87K barrels of oil and 1.95K 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.
