Gsh Unit #10H (API 42-013-34375) is a horizontal well in Atascosa County operated by Javelin Energy Partners Mgmt LLC, completed January 3, 2012 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued May 26, 2011, permitted to 10,437 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 1.43M barrels of oil and 1.36M mcf of gas since October 2011, last reporting volume in March 2026. The lease carries 10 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.
