Montgomery County · Conroe field · Shut In · Vertical
Conroe Field Unit #16 (API 42-339-30648) is a well in Montgomery County operated by Highmark Energy Operating LLC, completed July 29, 1984 and listed as shut in on the RRC schedule, shut in June 1, 2011.
The RRC has issued 2 drilling permits in 1984, permitted to 5,102 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 2nd Upper Cockfield, 3rd Main, 4th Main.
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.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
