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

Annie Trial ET AL #8H (API 42-255-35527) is a horizontal well in Karnes County operated by Magnolia Oil & Gas Operating LLC, completed December 15, 2017 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued June 23, 2017, permitted to 11,000 ft.

It was permitted by Enervest Operating, L.L.C. and has since transferred to Magnolia Oil & Gas Operating LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Frio, Carrizo, Reklaw, Yegua.

Its lease has reported 2.13M barrels of oil and 3.77M mcf of gas since February 2017, last reporting in July 2026. The lease carries 6 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.
