Madeley AA & Da #11 (API 42-339-00630) is a plugged well in Montgomery County, plugged April 19, 2013, last operated by Denbury Onshore LLC.

The RRC has issued 2 drilling permits between 2002 and 2003, permitted to 4,945 ft.

It was permitted by Exxon Mobil Corporation and has since transferred to Denbury Onshore LLC on the wellbore schedule.

Its 3 leases have reported 26.7M barrels of oil and 61.4M mcf of gas since January 1993, last reporting in July 2026. The leases carry 666 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.
