Porter E. B. #4 (API 42-051-33130) is a horizontal well in Burleson County operated by Wildfire Energy Operating LLC, completed December 14, 1990 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued October 22, 1990, permitted to 8,600 ft.

It was permitted by Williams, Clayton W., JR., Inc. and has since transferred to Wildfire Energy Operating LLC on the wellbore schedule.

Completion filings report 2 formation tops, including Pecan Gap, Austin Chalk.

Its lease has reported 172K barrels of oil and 2.08M 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.
