Wiatrek Unit #4H (API 42-255-36113) is a horizontal well in Karnes County operated by Repsol Oil & Gas USA LLC, completed December 5, 2018 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued August 16, 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, Yegua, Reklaw.

Its lease has reported 3.59M barrels of oil and 5.99M mcf of gas since June 2018, last reporting in July 2026. The lease carries 21 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.
