Dimmit County · Briscoe Ranch (Eagleford) field · Producing · Horizontal
Stumberg Ranch Unit C #13H (API 42-127-36835) is a horizontal well in Dimmit County operated by Javelin Energy Partners Mgmt LLC, completed October 12, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 21, 2014, permitted to 7,235 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 3 leases have reported 1.03M barrels of oil and 4.37M mcf of gas since August 2015, last reporting in July 2026. The leases carry 16 wells, so these are lease totals, not this well alone.
