Deep Rock Etal -A- #10G (API 42-003-39931) is a well in Andrews County operated by Highmark Energy Operating LLC, completed October 2, 2006 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued August 17, 2006, permitted to 6,150 ft.

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

Completion filings report 3 formation tops, including Queen, San Andres, Glorieta.

Its lease has reported 1.65M barrels of oil and 161K mcf of gas since January 1993, last reporting in July 2026. The lease carries 9 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.
