Conroe Field Unit #3504
Montgomery County · Conroe field · Temp Abandoned · Vertical
Conroe Field Unit #3504 (API 42-339-00663) is a well in Montgomery County operated by Highmark Energy Operating LLC, completed August 9, 2000 and listed as temp abandoned on the RRC schedule, shut in November 1, 2009.
The RRC has issued one drilling permit, issued August 18, 1997, permitted to 5,100 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 26.7M barrels of oil and 63.1M 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.
Operator of record
Permitted by Exxon Corp.; the EWA schedule now lists a different operator.
