Atascosa County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
TG Unit #31H (API 42-013-34404) is a horizontal well in Atascosa County operated by Javelin Energy Partners Mgmt LLC, completed April 28, 2012 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended 4 times), issued August 2, 2011, permitted to 10,166 ft.
It was permitted by Carrizo Oil & Gas, Inc. and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Carrizo, Austin Chalk, Eagle Ford.
Its lease has reported 1.39M barrels of oil and 1.1M mcf of gas since February 2012, last reporting volume in March 2026. The lease carries 7 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.
Wells nearby
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.
