Miesch B Unit #12H (API 42-283-36079) is a horizontal well in La Salle County operated by Javelin Energy Partners Mgmt LLC, completed December 17, 2017 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 23, 2017, permitted to 11,000 ft.
It was permitted by Carrizo (Eagle Ford) LLC and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Its lease has reported 379K barrels of oil and 1.16M mcf of gas since July 2015, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
