Marsh Unit #1 (API 42-051-33462) is a horizontal well in Burleson County operated by Wildfire Energy Operating LLC, completed February 3, 1995 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued January 3, 1995, permitted to 9,629 ft.
It was permitted by Williams, Clayton Energy, Inc. and has since transferred to Wildfire Energy Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Austin Chalk.
Its lease has reported 172K barrels of oil and 26.3K mcf of gas since January 1995, last reporting volume in March 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
