Miesch A Unit #22H (API 42-283-35524) is a horizontal well in La Salle County operated by Javelin Energy Partners Mgmt LLC, completed October 11, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued June 17, 2015, permitted to 7,460 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 237K barrels of oil and 171K mcf of gas since July 2015, last reporting volume in August 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
