Conroe Field Unit #1 (API 42-339-00817) is a well in Montgomery County operated by Highmark Energy Operating LLC, completed August 23, 1985.

The RRC has issued one drilling permit, issued April 16, 2007, permitted to 4,570 ft.

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

Its 3 leases have reported 26.7M barrels of oil and 66.2M 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.
