Sponberg J. O. #B 1 (API 42-355-00331) is a well in Nueces County operated by Urban Oil & Gas Group LLC, completed January 1, 1996 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued December 8, 1995, permitted to 7,500 ft.
It was permitted by Pennzoil Exploration & Prod. CO. and has since transferred to Urban Oil & Gas Group LLC on the wellbore schedule.

Its 2 leases have reported 4.03K barrels of oil and 257K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
