Marie B #12WA (API 42-317-41239) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed September 13, 2018 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued January 31, 2018, permitted to 9,500 ft.

It was permitted by Qep Energy Company and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Santa Rosa, Yates, Queen, Grayburg.

Its lease has reported 758K barrels of oil and 1.89M mcf of gas since September 2018, last reporting in July 2026. The lease carries 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.
