Middlebrook A #4 (API 42-157-32415) is a plugged well in Fort Bend County, plugged December 9, 2010, last operated by Atlas Operating LLC.

The RRC has issued 2 drilling permits (amended once) between 2006 and 2007, permitted to 6,800 ft.

It was permitted by Sue-Ann Operating, L.C. and has since transferred to Atlas Operating LLC on the wellbore schedule.

Completion filings report one formation top, including Frio.

Its 2 leases have reported 54.5K barrels of oil and 33.5K mcf of gas since July 2006, last reporting in July 2026. The leases carry 3 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.
