Korth B Unit #20H
Karnes County · Sugarkane (Austin Chalk) field · Producing · Horizontal
Korth B Unit #20H (API 42-255-35464) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed November 22, 2025 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued May 16, 2017, permitted to 11,300 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.
Completion filings report 10 formation tops, including Yegua, Queen City, Reklaw, Carrizo.
Its lease has reported 2.31M barrels of oil and 4.94M mcf of gas since November 2017, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
