Vineyard HZ L Unit #9701MS (API 42-317-41408) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed April 5, 2019 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued April 26, 2018, permitted to 10,000 ft.

It was permitted by Ajax Resources, 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 2.5M barrels of oil and 3.31M mcf of gas since June 2018, last reporting in July 2026. The lease carries 9 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.
