Carter Unit #8H (API 42-055-35123) is a horizontal well in Caldwell County operated by Texian Operating Company LLC, completed June 10, 2018 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 31, 2018, permitted to 3,500 ft.
It was permitted by North South Oil, LLC and has since transferred to Texian Operating Company LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Buda, Edwards, Eagle Ford.
Its lease has reported 534K barrels of oil since April 2009, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
