Collins Oil Unit #12U (API 42-365-34134) is a well in Panola County operated by Diversified Production LLC, completed September 13, 2002 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits (amended twice) between 1999 and 2002, permitted to 9,650 ft.

It was permitted by Devon Energy Production CO, L.P. and has since transferred to Diversified Production LLC on the wellbore schedule.

Completion filings report 6 formation tops, including Paluxy, Glen Rose, BMA, Sligo.

Its 3 leases have reported 102K barrels of oil and 1.47M mcf of gas since October 1999, last reporting in July 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.
