Henderson #8H (API 42-123-32913) is a horizontal well in De Witt County operated by Ensign Natural Resources II LLC, completed March 30, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued October 17, 2012, permitted to 13,280 ft.

It was permitted by Marathon Oil EF LLC and has since transferred to Ensign Natural Resources II LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.

Its 2 leases have reported 312K barrels of oil and 3.85M mcf of gas since June 2012, last reporting in July 2026. The leases carry 11 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.
