Champman J.O. #84 (API 42-355-30502) is a plugged well in Nueces County, plugged September 29, 2016, last operated by Decker Operating CO. L.L.C..

The RRC has issued 5 drilling permits between 1986 and 2000, permitted to 7,557 ft.

It was permitted by Shana Petroleum Company and has since transferred to Decker Operating CO. L.L.C. on the wellbore schedule.

Completion filings report 8 formation tops, including Lagarto, Oakville, Catahoula, Anahuac.

Its 8 leases have reported 26.6K barrels of oil and 106K mcf of gas since January 1993, last reporting in May 2020. The leases carry 12 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
