Halsell Ranch #503 (API 42-323-30262) is a plugged well in Maverick County, plugged October 16, 2006, last operated by Cmr Energy L.P..

The RRC has issued one drilling permit, issued August 28, 2001, permitted to 1,928 ft.

It was permitted by Exploration Company, The and has since transferred to Cmr Energy L.P. on the wellbore schedule.

Completion filings report 2 formation tops, including Olmos, San Miguel.

Its 2 leases have reported 14.8K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 14 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.
