Cypert D 57-51 #243 (API 42-317-42178) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed October 12, 2019 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued March 19, 2019, permitted to 11,000 ft.

It was permitted by Endeavor Energy Resources L.P. 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 644K barrels of oil and 3.42M mcf of gas since April 2019, 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.
