Conroe Field Unit #1946 (API 42-339-30676) is a well in Montgomery County operated by Highmark Energy Operating LLC, completed June 8, 1990.

The RRC has issued one drilling permit, issued September 7, 1984, permitted to 5,650 ft.

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

Completion filings report 7 formation tops, including 1st Upper Cockfield, 2nd Upper Cockfield, 1st Main, 2nd Main.

Its 2 leases have reported 26.7M barrels of oil and 61.8M 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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
