Mcmillian W. D. #1R (API 42-481-33993) is a plugged well in Wharton County, plugged June 12, 2003, last operated by Carrizo Oil & Gas Inc..

The RRC has issued 3 drilling permits between 1997 and 2011, permitted to 10,500 ft.

It was permitted by Caza Operating, LLC and has since transferred to Carrizo Oil & Gas Inc. on the wellbore schedule.

Completion filings report one formation top, including Yegua.

Its 3 leases have reported 292 barrels of oil and 3.77M mcf of gas since January 1998, 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.
