Wessendorff A Unit #16H (API 42-255-35465) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed October 1, 2017 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued May 19, 2017, permitted to 13,034 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 470K barrels of oil and 1.72M mcf of gas since December 2012, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
