Shook Efs #21H (API 42-127-33676) is a horizontal well in Dimmit County operated by Atlas Operating LLC, completed July 16, 2010 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued March 30, 2010, permitted to 6,400 ft.
It was permitted by Redemption Oil & Gas, LLC and has since transferred to Atlas Operating LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Wilcox, Escondido, San Miguel, Anacacho.
Its lease has reported 715K barrels of oil and 5.34M mcf of gas since July 2010, last reporting in July 2026. The lease carries 13 wells, so these are lease totals, not this well alone.
