Margaret M4 (Alloc-2sh) #6LL (API 42-317-41316) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed November 13, 2018 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued February 27, 2018, permitted to 9,636 ft.

It was permitted by Guidon Energy Mgmt Services LLC 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 808K barrels of oil and 1.9M mcf of gas since November 2018, last reporting in July 2026. The lease carries 2 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.
