George Holt Glass West E 13-1 #4305H (API 42-317-44981) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed October 6, 2025 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended twice), issued January 11, 2023, permitted to 10,605 ft.

It was permitted by De IV Operating, LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.

Its lease has reported 338K barrels of oil and 455K mcf of gas since October 2025, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
