White W. H. 504 #4 (API 42-467-30772) is a well in Van Zandt County operated by Basa Resources Inc., completed February 20, 1990 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued December 4, 1989, permitted to 3,350 ft.

It was permitted by Union Expl. Partners, Ltd. and has since transferred to Basa Resources Inc. on the wellbore schedule.

Completion filings report 3 formation tops, including Nacatosh, Pecan Gap, Austin Chalk.

Its lease has reported 233K barrels of oil and 332K mcf of gas since January 1993, last reporting in July 2026. The lease carries 6 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.
