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

Julie Beck #12 H (API 42-255-33249) is a horizontal well in Karnes County operated by Marathon Oil EF LLC, completed October 9, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued July 2, 2013, permitted to 11,764 ft.

It was permitted by Aurora USA Development, LLC and has since transferred to Marathon Oil EF LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.

Its lease has reported 2.55M barrels of oil and 14.9M mcf of gas since December 2010, last reporting in July 2026. The lease carries 16 wells, so these are lease totals, not this well alone.
