Kothmann-Ranch #9H (API 42-163-33712) is a horizontal well in Frio County operated by Javelin Energy Partners Mgmt LLC, completed July 18, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued April 23, 2013, permitted to 8,400 ft.

It was permitted by EF Energy, L.L.C. and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

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

Its lease has reported 1.36M barrels of oil and 1.63M mcf of gas since July 2011, last reporting in July 2026. The lease carries 14 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.
