Conroe Field Unit #4215 (API 42-339-00555) is a well in Montgomery County operated by Highmark Energy Operating LLC, completed June 4, 1986 and listed as shut in on the RRC schedule, shut in June 1, 2003.

The RRC has issued one drilling permit, issued May 5, 1986, permitted to 5,119 ft.

It was permitted by Exxon Corp. and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.

Its 2 leases have reported 26.9M barrels of oil and 64.2M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 692 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.
