Karnes County · Eagleville (Eagle Ford-2) field · Temp Abandoned · Horizontal
Wessendorff A Unit #8H (API 42-255-35346) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed February 27, 2018 and listed as temp abandoned on the RRC schedule, shut in February 1, 2023.
The RRC has issued one drilling permit, issued February 28, 2017, permitted to 13,024 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 752K barrels of oil and 3M mcf of gas since December 2012, last reporting volume in April 2026. The leases carry 11 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Mar 5, 2021. Gamma ray. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
