Monson Unit #9H
Karnes County · Eagleville (Eagle Ford-2) field · Horizontal
Monson Unit #9H (API 42-255-34718) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed January 20, 2016.
The RRC has issued one drilling permit, issued September 17, 2015, permitted to 13,100 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 2 leases have reported 1.64M barrels of oil and 5.64M mcf of gas since February 2012, last reporting in July 2026. The leases carry 10 wells, so these are lease totals, not this well alone.
