Shook Efs #204H (API 42-127-36337) is a horizontal well in Dimmit County operated by Atlas Operating LLC, completed November 29, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued May 21, 2014, permitted to 6,400 ft.

It was permitted by Sea Eagle Ford, LLC and has since transferred to Atlas Operating LLC on the wellbore schedule.

Completion filings report 9 formation tops, including Escondido, Olmos, San Miguel, Austin Chalk.

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.
