Hall Trust 38 #1 (API 42-317-35658) is a well in Martin County operated by Diamondback E&P LLC, completed January 14, 2010 and listed as shut in on the RRC schedule, shut in August 1, 2025.

The RRC has issued one drilling permit, issued August 21, 2009, permitted to 10,760 ft.

It was permitted by Cobra Oil & Gas Corporation 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 271K barrels of oil and 571K mcf of gas since November 2009, 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.
