Billie Ann #1
Bastrop County · Serbin (Wilcox) field · Producing · Vertical
Billie Ann #1 (API 42-021-31104) is a well in Bastrop County operated by Sheldon Resources L.P., completed November 13, 1987 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued October 7, 1987, permitted to 5,528 ft.
It was permitted by Maxwell Oil & Gas Corp. and has since transferred to Sheldon Resources L.P. on the wellbore schedule.
Completion filings report 3 formation tops, including Midway, Navarro, Taylor.
Its lease has reported 130K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
Operator of record
