Korth C Unit #10H (API 42-255-34978) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed March 9, 2017 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued March 28, 2016, permitted to 11,600 ft.
It was permitted by Encana Oil & Gas(USA) Inc. and has since transferred to Devon Energy Production CO L.P. on the wellbore schedule.

Its lease has reported 2.45M barrels of oil and 4.79M mcf of gas since March 2017, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
