Riesling #8 (API 42-317-38037) is a well in Martin County operated by Diamondback E&P LLC, completed February 7, 2014 and listed as shut in on the RRC schedule, shut in April 1, 2025.

The RRC has issued one drilling permit, issued August 8, 2012, permitted to 10,500 ft.

It was permitted by W&T Offshore, Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.

Its lease has reported 295K barrels of oil and 311K mcf of gas since March 2009, 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.
