Kothmann-Ranch #12H (API 42-163-33854) is a horizontal well in Frio County operated by Javelin Energy Partners Mgmt LLC, completed November 29, 2014 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit (amended twice), issued July 29, 2014, permitted to 8,400 ft.

It was permitted by Cabot Oil & Gas Corporation and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Queen City, Escondido, Navarro, Olmos.

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.
