Bastrop County · Cistern North field · Producing · Vertical
Naumann ET AL #3 (API 42-021-31136) is a well in Bastrop County operated by Sellers Lease Service Inc., completed April 19, 1988 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued February 8, 1988, permitted to 2,000 ft.
It was permitted by Mca Petroleum Corporation and has since transferred to Sellers Lease Service Inc. on the wellbore schedule.
Completion filings report one formation top, including Wilcox.
Its lease has reported 38.2K barrels of oil and 21 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.
Operator of record
