Conroe Field Unit #1945 (API 42-339-30636) is a well in Montgomery County operated by Highmark Energy Operating LLC, completed April 26, 2011 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits in 1984, permitted to 5,100 ft.

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

Completion filings report 8 formation tops, including Main Conroe 2a, Mc Ra, Mc Rbi-2, Main Conroe 2b3.

Its lease has reported 26.8M barrels of oil and 61.4M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 664 wells, so these are lease totals, not this well alone.
