Apollo Unit #8H (API 42-255-35707) is a horizontal well in Karnes County operated by Caturus Energy LLC, completed May 19, 2018 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued December 11, 2017, permitted to 11,000 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 1.15M barrels of oil and 4.62M mcf of gas since November 2017, last reporting in July 2026. The lease carries 14 wells, so these are lease totals, not this well alone.
