Monson Unit #8H (API 42-255-34717) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed January 20, 2016 and listed as shut in on the RRC schedule.

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 lease has reported 1.64M barrels of oil and 5.13M mcf of gas since February 2012, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
