Conroe Field Unit #2718 (API 42-339-30512) is a well in Montgomery County operated by Highmark Energy Operating LLC, completed October 5, 1990.

The RRC has issued one drilling permit, issued July 6, 1981, permitted to 5,700 ft.

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

Completion filings report 8 formation tops, including 2nd Upper Cockfield, Upper Cockfield, Cockfield 1-A, Cockfield 1a.

Its lease has reported 26.7M barrels of oil and 61.4M mcf of gas since January 1993, last reporting in July 2026. The lease carries 664 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
