Stumberg Ranch Unit C #10H (API 42-127-36700) is a horizontal well in Dimmit County operated by Javelin Energy Partners Mgmt LLC, completed April 23, 2017 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued October 2, 2014, permitted to 7,203 ft.

It was permitted by Anadarko E&P Onshore LLC and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Completion filings report 11 formation tops, including Midway, Escondido, Olmos, San Miguel.

Its 2 leases have reported 1.03M barrels of oil and 4.15M mcf of gas since May 2015, last reporting in July 2026. The leases carry 15 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.
