Montgomery County · Conroe field · Producing · Vertical
Conroe Field Unit #1718 (API 42-339-30500) is a well in Montgomery County operated by Highmark Energy Operating LLC, completed June 9, 2017 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued February 18, 1981, permitted to 5,200 ft.
It was permitted by Exxon Corp. and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.
Completion filings report 4 formation tops, including 1 A Main, 1a Main, 1st Main, 2a Main.
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.
