Dubose #4H (API 42-177-32126) is a horizontal well in Gonzales County operated by Marathon Oil EF LLC, completed June 29, 2011 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 1, 2010, permitted to 11,400 ft.
It was permitted by Union Gas Operating Company 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 139K barrels of oil and 281K mcf of gas since December 2010, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
