Shut in

Montgomery County · Conroe field · Temp Abandoned · Vertical

Conroe Field Unit #36 (API 42-339-30422) is a well in Montgomery County operated by Highmark Energy Operating LLC, completed February 24, 1998 and listed as temp abandoned on the RRC schedule, shut in May 1, 2011.

The RRC has issued 3 drilling permits between 1978 and 2000, permitted to 9,255 ft.

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

Its 2 leases have reported 26.7M barrels of oil and 61.6M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 665 wells, so these are lease totals, not this well alone.
