Mzyk North Unit #7H (API 42-255-35925) is a horizontal well in Karnes County operated by Repsol Oil & Gas USA LLC, completed August 12, 2018 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 1, 2018, permitted to 12,500 ft.

It was permitted by Gulftex Energy IV, LP and has since transferred to Repsol Oil & Gas USA LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Frio, Carrizo, Reklaw, Yegua.

Its lease has reported 2.2M barrels of oil and 3.51M mcf of gas since May 2017, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
