Conroe Field Unit #3910 (API 42-339-30712) is a well in Montgomery County operated by Highmark Energy Operating LLC, completed December 8, 1998 and listed as temp abandoned on the RRC schedule, shut in November 1, 2017.
The RRC has issued one drilling permit, issued March 20, 1985, permitted to 5,700 ft.
It was permitted by Exxon Corp. and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including 1st Main, 2nd Main, 3rd Main.
Its 2 leases have reported 26.7M barrels of oil and 61.8M 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.
