Wostal State #4 (API 42-131-39632) is a well in Duval County operated by Paloma Operating LLC, completed February 15, 2020 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued October 21, 2019, permitted to 3,000 ft.

It was permitted by Double Play Oil & Gas, Inc and has since transferred to Paloma Operating LLC on the wellbore schedule.

Completion filings report 8 formation tops, including Miocene (undifferentiated), Catahoula, Vicksburg, Jackson.

Its lease has reported 27.6K barrels of oil since April 2013, last reporting in July 2026. The lease carries 2 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.
