Obregon B #11 (API 42-187-33349) is a well in Guadalupe County operated by Luling Well Service, completed November 30, 1990.
The RRC has issued one drilling permit, issued November 5, 1990, permitted to 2,500 ft.
It was permitted by Entex Equity Group, Inc. and has since transferred to Luling Well Service on the wellbore schedule.
Completion filings report 3 formation tops, including Austin Chalk, Eagle Ford, Buda.
Its lease has reported 16K barrels of oil and 220 mcf of gas since January 1993, last reporting in July 2026. The lease carries 11 wells, so these are lease totals, not this well alone.
