Jordan Unit #1H (API 42-255-31817) is a horizontal well in Karnes County operated by Marathon Oil EF LLC, completed May 7, 2021 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued December 17, 2010, permitted to 11,962 ft.
It was permitted by Hilcorp Energy 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 1.18M barrels of oil and 2.54M mcf of gas since May 2011, last reporting volume in August 2026. The lease carries 7 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.

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.
