Karnes County · Eagleville (Eagle Ford-2) field · Shut IN  · Horizontal

Darlene Unit #4H (API 42-255-32297) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed September 16, 2013 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued January 31, 2012, permitted to 13,700 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 1.1M barrels of oil and 1.22M mcf of gas since December 2010, last reporting in July 2026. The lease carries 7 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.
