Conroe Field Unit #3531 (API 42-339-30707) is a well in Montgomery County operated by Highmark Energy Operating LLC, completed January 24, 2000 and listed as temp abandoned on the RRC schedule, shut in October 1, 2002.

The RRC has issued one drilling permit, issued February 12, 1985, permitted to 5,350 ft.

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

Completion filings report 10 formation tops, including 1 Main Conroe, 1st Main Conroe, 2 Main Conroe, 2nd Main Conroe.

Its 2 leases have reported 26.7M barrels of oil and 63.5M mcf of gas since January 1993, last reporting in July 2026. The leases carry 665 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.
