EC South Unit #2H (API 42-013-35582) is a horizontal well in Atascosa County operated by Trailblazer Energy Resources LLC, completed October 26, 2018 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued April 24, 2018, permitted to 9,000 ft.

It was permitted by Cinco Oil & Gas, LLC and has since transferred to Trailblazer Energy Resources LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Queen City, Reklaw, Carrizo, Wilcox.

Its lease has reported 357K barrels of oil and 227K mcf of gas since October 2018, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
