Karnes County · Eagleville (Eagle Ford-2) field · Shut In · Horizontal
Wessendorff A Unit #1H (API 42-255-32436) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed December 5, 2012 and listed as shut in on the RRC schedule, shut in December 1, 2024.
The RRC has issued one drilling permit (amended once), issued April 17, 2012, permitted to 13,062 ft.
It was permitted by Petrohawk Operating Company and has since transferred to Devon Energy Production CO L.P. on the wellbore schedule.
Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.
Its lease has reported 470K barrels of oil and 1.72M mcf of gas since December 2012, last reporting volume in April 2026. The lease carries 10 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Feb 8, 2016. Density, Neutron, Resistivity. 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.
