Hull A-21 Unit #A 36 (API 42-365-32038) is a well in Panola County operated by Diversified Production LLC, completed March 28, 2017 and listed as producing on the RRC schedule.

The RRC has issued 3 drilling permits (amended once) between 1989 and 2017, permitted to 9,620 ft.

It was permitted by Sheridan Production Company, LLC and has since transferred to Diversified Production LLC on the wellbore schedule.

Completion filings report 7 formation tops, including Paluxy, Glen Rose, BMA, Pettit.

Its 3 leases have reported 23.2K barrels of oil and 1.36M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 3 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.
