Campbell Estate #2 (API 42-409-31493) is a plugged well in San Patricio County, plugged April 15, 2006, last operated by Dual S Production LLC.
The RRC has issued 3 drilling permits between 1981 and 1993, permitted to 5,900 ft.
It was permitted by Trident Corporation and has since transferred to Dual S Production LLC on the wellbore schedule.
Its 3 leases have reported 2.51K barrels of oil and 37.8K mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
