Cundieff #203H (API 42-323-33535) is a horizontal well in Maverick County operated by Jonah Energy LLC, completed May 21, 2021 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 21, 2020, permitted to 4,000 ft.
It was permitted by Endeavor Natural Gas, LP and has since transferred to Jonah Energy LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Olmos, San Miguel, Eagle Ford, Buda.
Its lease has reported 954K barrels of oil and 3.24M mcf of gas since March 2017, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
