Atlas Unit #204H (API 42-255-35909) is a horizontal well in Karnes County operated by Caturus Energy LLC, completed July 10, 2018 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued April 16, 2018, permitted to 11,500 ft.
It was permitted by Blackbrush O & G, LLC and has since transferred to Caturus Energy LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Yegua, Queen City, Reklaw, Carrizo.
Its lease has reported 374K barrels of oil and 978K mcf of gas since September 2017, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
