Montgomery County · Conroe field · Shut In · Vertical
Conroe Field Unit #3540 (API 42-339-30831) is a well in Montgomery County operated by Highmark Energy Operating LLC, completed June 5, 2009 and listed as shut in on the RRC schedule, shut in June 1, 2012.
The RRC has issued 2 drilling permits between 1989 and 1997, permitted to 5,230 ft.
It was permitted by Exxon Corp. and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.
Completion filings report 9 formation tops, including Moodys Branch, 1st Up. Cockfield, Main Conroe Sands, 1m.
Its 2 leases have reported 26.7M barrels of oil and 62.1M 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.
