Dziuk Unit #1H
Karnes County · Eagleville (Eagle Ford-2) field · Shut In · Horizontal
Dziuk Unit #1H (API 42-255-31812) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed May 3, 2013 and listed as shut in on the RRC schedule, shut in December 1, 2025.
The RRC has issued one drilling permit (amended once), issued December 7, 2010, permitted to 10,986 ft.
It was permitted by Plains Exploration & Prod. CO. 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 417K barrels of oil and 618K mcf of gas since December 2010, last reporting volume in April 2026. The lease carries 4 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.
Wells nearby
Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
1 log loaded from the RRC's log index, the latest received Dec 19, 2013. 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.

"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.
